Fuel Starvation Control Product

clintfocus

ok so ive only been here since then, and only had my Z since nov 2010, but first time on track i got it to starve on less then full tank, causei have alot of past track experience prior to 370 ownership, its no less frustrating to me.

maybe because my time attack car, which is a focus, had such a tiny aftermarket for anything, this to me sounds like small potatos to me compaired to race level stuff that wasnt avalible for my focus chassis that either took forever to come out, or i just ended up having to be made custom. so i understand everyone who is serious about buying this product is anxious, but take a step back maybe and a deep breath. hell i had to deal with not even being able to buy wheels wide enough cause of bolt pattern for the focus, waiting two years to save up money and have wheels made then shipped over. thats just one example, and its prolly why i guess im not as bothered

I'm frustrated too but still willing to wait and just deal with it in the meantime. Today I consistently hit fuel starve with a dot over 3/4 tank (about 5 gallons when I went to fill up). Having to do that a few times per track day sucks, but it's manageable until we get this fix. I support you phunk.

Ok Shamu, tell us what we're looking at.

Looks like a homebrew solution to keep a small amount of fuel near the pickup when the tank tries to starve it.

close. i wouldnt touch that setup with a 10 foot pole but i can tell what they are doing. that photo is on the drivers side of the tank, opposite from where the main fuel pump resides. They have a canister secured poorly with stainless wire, using a couple check valves that will (in theory) allow fuel in the canister but not out, and a fuel pump pickup for an additional pump that is transfering fuel to the passenger side (main fuel pump).

this solution will not last, as their transfer pump is going to be running very dry most the time, especially if used for any street driving where once below a half tank, the driver side is completely empty (thanks to the factory transfer siphon) unless you slosh it over on a right hander. sure you could put this pump on a toggle switch and only use it when on the track... but this is not the type of solution that any professional business would market as a product, its an unreliable bandaid.

"solutions" like this are exactly why i needed to make something.

Install kit and technique was finished today. Changed the size of one of the fittings, ordering more right now. Should be here by Friday. Going to ship 2 of the units out Friday as long as the fittings show. I might wait for those 2 guys to finish install and give me feedback before shipping the rest.

machine time, material costs, parts costs, installation components costs, etc.. were all worked out today.

we have all the pricing setup now. i will make it public thursday or friday. i just want another day or two to look at it a few more times and decide if its final.

ordered up enough of the installation materials for the first few kits... supposedly they being 2nd day shipped today. so its looking pretty positive that the first 2 are going to be able to ship out Friday. these 2 guys are thinking they should be able to get to the installation right away. so I am hoping that while I am working on packing up the rest of the kits and getting them ready to ship, perhaps I can get some installation and testing feedback from them before shipping the rest just to make sure everything looks OK.

to come up with the installation parts, i had to go ahead and do a mock up installation on a spare 370z fuel tank we have here. the work on the drivers side of the tank turned out not to be as bad as I thought it was going to be... probably no big deal. the passenger side is a little more of a pain IMHO. whats left to be seen is how much more difficult it is to do inside the vehicle, since its obviously more convenient to do to a tank sitting on a table.

a little photo i took when beginning the mockup install. as you can see i cut open the top/middle of the fuel tank so that we could see whats going on and also provide better photos for installation directions. even though you will not get as good of a perspective in your tank, this makes it easier for us to show you what you are working with inside there when i take more photos.

notice the corner of the baffle pointing at the level sensor... it has to be bent out of the way a little or the level sensor arm will contact it and then the fuel gauge would be unable to read full. i wanted to avoid having to do that, but mounting the level sensor on the outside diameter of the canister compared to how it hangs stock, left us very little room to play for giving the sensor full swing.

this unit is my personal one... the retail ones are anodized blue and not beat up.
