New Product: CJ Motorsports Fuel Pump Hat
 

[BR]
Now available, a relatively simple new fuel system upgrade from CJ Motorsports has begun to ship. This billet aluminum top plate for the factory fuel pump module is intended to be a straight-forward replacement to the factory plastic top plate. This product is a stand-alone upgrade, adaptable to any 370z fuel system that still has the factory fuel pump module. Using our stock-type installation kit, this can be added to an otherwise entirely unmodified vehicle, one with a simple fuel pump upgrade, or one with the CJM Road Race Pump. Add it to return fuel system equipped vehicles with other available installation kits, or build your own custom installation.


Why would you want this? Aside from looking pretty in a place that nobody will ever see it (once installed), there are some good reasons you might be interested.

RIGIDITY: The factory plastic top hat is soft and deforms and has begun to start entirely failing on people. Through use, they first develop "the lean", and eventually they just let go. When this happens it is anyone's guess if your Z will run or not, as the lower section of the fuel pump module is hanging off its wires in your fuel tank. Nissan wont sell you just the top plate, so you have to either spend big bucks to replace the entire fuel pump module, or find a used one with unknown lifespan remaining.

Our aluminum design accepts the factory stainless support rods and supports them inside sturdy aluminum stands. The support rod bores are stepped diameter to secure the rods from any lateral movement by bracing them, not only where they exit the stands, but in the deepest portion of the bore.

Stainless wedge-type set screws come in at 45 degrees to lock the support rods in place. The tip of the set screws locks up to rods just under a ledge point, ensuring they cannot pull out. See the assembled CAD cutaway below:


6-Position Electrical Bulkhead & Ground Stud: The factory connector is 5 positions, and that is all most people will need. But if you have an upgraded fuel pump, the factory wiring is not cut-out for the job. Even with upgraded wiring and/or relays, your 5-position connector has tiny terminals intended for tiny wires.


What you are looking at here is the charred and brittle plastic surrounding the fuel pump power wire on the factory top plate. It isn't the best photo, but notice how part of the plastic became brittle enough to just chip away. This is an example of how the small factory terminals just are not intended for the current draw of upgraded fuel pumps.

Our connector system was OEM engineered for greater current and the terminals support 12 and 10AWG wiring. The 6-position connector system consists of a bulkhead (sealed to the billet plate with a Viton o-ring), and internal and external disconnects.

For most installs, you will only use 5 of the 6 available positions. But we wanted this product to accommodate custom projects too. With a left over position in the connector, and the integrated ground stud, you can easily provide power and ground for an auxiliary fuel pump project.


VERSATILITY: With 3x 6AN bulkhead openings, this top plate can accommodate just about any fuel system configuration. We offer an installation kit for stock fuel system vehicles, as well as an installation kit for integration with our latest return fuel systems. More installation kits will be coming, or can be assembled on request for your fuel system.


MADE IN THE USA

Installation details are coming. Photos of the process have been taken and will be put into a PDF.

SOME ELECTRICAL AND WIRING EXPERIENCE IS REQUIRED. To install this product will involve removing the factory fuel pump connector, crimping new terminals to the wires, and adding the terminals to the connectors. This is not terribly difficult, but I understand that some people just do not get along with wiring.

HEAT GUN or a good hair dryer are required to install the convoluted PTFE hose.

If you have any questions, please feel free to post them. I would like to address anything I am forgetting!

Thanks!

This is awesome! Love the color too ;)

Got mine in the mail today

Got mine too, thanks!

Any 350Z love?

Absolutely, We've had a billet pump for 350z for years!

Got mine installed with the RRP. Took a bit of creative thinking between phone and myself but we made it work. Shouldn't be an issue for future RRP installs and a stock pump replacement will be cake. Excellent product and happy to the last piece to a bullet proof fuel system for the track.

Is this item compatible with the AAM Stage 1 fuel return, and an upgraded Aeromotive 340 pump?

Thanks again for working through it with me! Its very helpful to get that type of feedback from installers!

Yes it definitely would be. If you happen to have a photograph of your fuel pump module after the AAM Stage 1 return conversion, it would help me verify that I send you a compatible installation kit. But I am about 99% sure I already know which combination of installation hardware you would need for that.

Thanks! Everything is just parts now; starting a new TT/built block setup :yum:. My fuel gauge has already failed (always reads half full) and I'm not sure if it's the pump assembly sending unit or the #2 sending unit. I should find out once shop begins the work, and I'll send a photo when they get to the tank.

Sounds great. You can also send over a photo of the parts going into the fuel pump module, and that would also suffice for me, as I would be able to tell where it all goes and what is needed to connect to it correctly.

So mine is on its last legs after doing the RRP install. What install kit do I need for my S1 return system?

Good question, I havent added the install kit for the "legacy" S1 and S1-S fuel systems (L1 type return, stock output and -4 return bulkhead) to the website yet.

The install kit for that would be almost identical to L2 kit, except it just hooks up a little differently.

I also need to add the install kits for return systems with RRP. There are so many combinations that will have a small change! But I know now what needs to be done for each, I just have to get the all the options into the drop down menu.

I can put one together for you later today? If youd like PM or email me and I can get it squared away ASAP.

Thanks

Does running large concentrations of ethanol in fuel cause the stock fuel pump hat to fail sooner?

I currently have no reason to believe that the material is compromised by ethanol. I ran mine in nothing but E85 for over 3 years since last inspection and the OEM plastic showed no degradation of that type. It just had the "lean" going showing that it had deformed the same as any higher mileage ones I have seen.

Several customers have been ordering their new top hat with a new fuel system simultaneously.

I snapped a photo the other day while packing up the in-tank portion of a fuel system, top hat, fuel pump combo that was ordered.

These new fuel systems are setup to harness the full potential of the pump. The fuel pump output heads directly out of the hat via an OEM quality convoluted PTFE hose, bypassing the post-pump filter and regulator housing, and out the hat via our custom bulkhead fitting. We put a large Aeromotive filter under the car and new PTFE lined feed lines up to the engine.

Doing so, now even our entry level return systems have 100% upgraded high flow feed, without a single inch of the factory plumbing being retained for the feed side.

The return fuel is coming back through the original factory feed pipe, which is why you see our custom QD adapter for the return bulkhead on this top hat. From there, return fuel flows through a 3/8" softline to the CJM regulator delete fittings, to keep the factory venturi system on-line.

This Aeromotive pump will be getting all the juice it needs through our large-terminal fuel-rated connector system.

Always great stuff Charles. I have been running your Stage 1 return fuel system for nearly 2 years and i am very interested in this piece but i wanted to ask what else i could upgrade to my Stage 1 since usually on your page you sell almost everything in packages and there are pieces that i would not need. Would the L2 Fuel Pump and Return Mod be a good addition? Which seems like it is the combination on the photo above. Thanks!

Thanks!

Our L2 level of fuel pump modifications involves bypassing the internal fuel filter and using a larger output and then the stock feed re-purposed as the return. So if you wanted to move up to that, we would need to also package you an upgrade kit to take you all the way to the new S1.E fuel system with external filter.

If you chose to do this, between what you already have, and the billet hat with L2 install kit, you would not need to actually purchase the standalone L2 fuel pump modification kit. To complete the conversion would mean adding our external filter kit, and the 2 new feed hoses (from fuel pump to filter, and filter to engine).

That would be awesome! I saw the external filter on your webpage but was asking myself how can i get that part to do some minor upgrades to my Stage 1 fuel system since you don't seem to have it as a standalone piece. You got my attention Charles.

I have sent out several upgrades for S1 to S1.E and S1.S to S1.SE the last couple months! Lots of guys wanted the external filter so that they could cut out the stock one to put in the big Walbro 450. That was the primary purpose for remodeling those kits: to get the external filter integrated in (that is the ".E" added to the system name) to all of the kits.

I will PM you an itemized list/quote of what you need to get all current and upgraded!

Please do! if it makes any difference I'm also running a 340 in the fuel pump assembly instead of the OEM (Must've thrown it in the trash after the BP kit install)

I put together the installation kit today, and added it as an option on the website page!

PM sent also.

Thanks!

My latest fuel pump tech PDF includes notes on how to assembly the billet top hat: http://host.cj-motorsports.com/pdf/3...ump%20Tech.pdf

5 left in stock right now. Material for 50 more came in last week... it might be a few weeks more before I am able to cut them, but I am going to try to get them in ASAP.

Check out the before and after pics I got from a customer today who had to repair his module. He was running a totally stock fuel system and stock pump, so he used the "stock type" installation kit of course.

Still have any in stock ??

:tiphat:

I have a 2008 G37 coupe and will this fit on the older style pump?

Hello, the top is not removable from the older pump housing! The older one is much more rigid to begin with and does not have a problem with coming apart.

Hi phunk, any black Friday deals? I have your fuel pump kit and mini pressure gauge already,i need a fuel return kit and would like the new pump hat also, let me know what I need with the hat,i have a stage 2'sc kit,iam going to 12lbs of boost for next summer and running 109 unleaded ,I am in Canada so exchange sucks right now,let me know what you can do,thanks

I am too under-staffed to properly prepare for and market seasonal sales. In the next year or two of growth I hope to start implementing more strategic marketing techniques like that.

That said, when someone is going to make a decent size purchase with a couple items, it doesn't hurt to contact me directly to see what I can do for you ;) Especially if you already run a CJM product or two.

Thanks ,pm sent

There are currently 10 out being anodized black. The rest of them will be done blue next time we go in for a batch of blue parts, probably first week of January I would expect.

Of the 10 black ones coming back either end of this week or after christmas, 5 or 6 are still available.

Just a heads up to anyone waiting for them to come back.

Thanks!

So my CJM fuelport and mini pressure gauge would qualify me for a 50% discount on an S1.SE or S2 fuel system then? :ughdance:

Worth a shot!

Even better! I must have forgot to package your bonus fuel system with the gauge kit :)

Hey I need to get in on this 50% off deal! :D


Actually I do need to order some stuff, I'll pm you shortly

Feel free to send it along =) If it doesnt show up tomorrow I'll call the BBB. :eekdance:

Charles, I'm pretty sure my stock hat broke a while back. I just recently picked up a used RRP kit and I was initially thinking it would also solve the broken hat issue I have. But after reading over the installation, it looks like the RRP goes on the driver side, so I still need the replacement top hat for the passenger side. Is this correct?

I'll need to get a few missing bits from you for the RRP kit and might as well grab the billet top hat at the same time.

The RRP kit goes on the drivers side. So you will need to get the top hat kit for the pass side.

^^^ what he said. RRP works with the stock fuel pump module rather than replacing it.
