I thought to PM OP, but last time he logged in was Nov 2015.

I was browsing Z1's website and came across this Z1 kit, sounds a lot like what OP said?

Literature from Z1's site:

"The Z1 Motorsports Fuel Anti-Starvation Kit solves this issue by utilizing a secondary fuel pump which transfers fuel from the left-hand sump of the fuel tank directly into the OEM fuel pump basket. Thoroughly track tested at Road Atlanta, this kit eliminates the fuel starvation problem on a clockwise track particularly prone to cause fuel starvation problems on later model Nissan Z models."

I was talking to Spence from Z1 at ZDayZ. He was telling me about this kit. They use it on their race cars with no problems.

Couldn't find any install procedures for it, but the price is right. I wonder if the 2nd pump is just zip tied in as I do not see a bracket. Everything else looks pretty straight forward.

There not going to tell you anything different lol. Only time will tell. Someone will come along that doesn't want to spend on the CJM kit (hopefully someone who really drives the car hard on the track) and test it until it breaks. Only question i have, how long does that mat stay good for? Are you able to use different types of fuels and if that 2nd pump is zipped tied, is that zip able to with stand constant lateral G abuse. Phunk made a good statement about this product already.

I use a 15x15 in a fuel cell in our race car (not a Z) 15gl tank

We tried 2 fuel pick ups from rock crawlers and we suffered fuel starvation after the 9 go mark
After we went with a surge tank and 2 pumps , worked better but under high G loads the car would sputter and even shut off

Finally we went to the Hydramat and all fuel starvation problems are gone , only problem with the huge mat we use is , when you out of gas.....you getting trailered in ha ha

I would suspect what Z1 is doing with this setup would perform. As a self-proclaimed fuel system engineer, I am not 100% satisfied with the operating theory. But it is nothing I would attack, especially at the price point and simplicity.

This is a bit different than what I was talking about in my previous post to this thread, where I was addressing the project of adapting a Hydramat to the factory fuel pump module, which I predicted we would not see happen.

This kit is something the market needed. As much as I would obviously prefer to get every last sale I can... it is no secret that my production has not kept up with demand, or that my product is in a price range that not everyone can justify for their project.

This Z1 product is 43% the cost. I hope it offers some perspective to my customers as to why my product is priced where it is when you compare how much custom hardware each product is comprised of.

I am more than confident that my RRP can outperform this new product release, as no other solution without a integrated surge canister can offer the same fluid control. But I think Z1 made a smart move by offering an alternative product at a different price point than my RRP.

If it helps more Z's get out there and kickass and show off, it ultimately helps all businesses in the business of Z's.

I am really looking into getting this kit to prevent starvation issues at Mid-Ohio. My car is a DD with occasional track use and I am just wondering, on quarter tank of fuel or less on the road, say turning left to get onto the highway and then cruising down a straight highway, would this new pump starve and get ruined because all the fuel is to the passenger area and can't get above the hump? Interested to hear your opinion, Phunk.

Yes any pump on the driver side of the tank used on the street under any conditions will be starving constantly unless you keep the tank over half full or turn it off.

That's what I was afraid of. So to really make a bulletproof system you'd have to get a T or Y fitting and put another HydraMat on the passenger side so no matter what the driver side pump is always getting fed. Probably going to be another $250 going that route.

How hard would it be to wire a switch in to the cabin for the second pump? Put it next to the traction/stability bypass switch and engage when necessary?

Ya, that's what I realized would be much easier and cheaper. I am planning on drilling a hole in the top of the sending unit and mounting a rubber plug that I'll put 2 small holes in and run the wires through them to and from the switch. The holes will be undersized so hopefully there won't be any leakage. I've also verified the plugs can handle gasoline and won't deteriorate. I am also planning to put the switch in one of my dead spaces where the heated seat switches would go as I don't have heated seats. I think this should work out really well. It seems Z1 just needed to do a bit more engineering and they would have nailed a perfect and reasonably cheap solution to the fuel-starvation issue for road and track use.

Thread bump, because I'm pulling this trigger on a fuel starve solution before events start up again in the spring...

What's Z1's kit missing, or has as a potential deal-breaker?
Is it that both pumps are constantly running?

Both pumps run all the time. I have one installed and it has performed as advertised. I don't daily drive mine very much anymore and I run e85 with 1000cc injectors so mpgs don't matter to me as much as having a reliable fuel system at the track.

Just an update on my experience with the Z1 anti-fuel starvation kit. This weekend I ran my fuel content down to two dots or less on 3 separate occasions and had no issues with fuel starvation regardless of hard continuous right hand turn or hard full throttle runs.

Edit: Phunk point out that I don't know my left from my right as originally posted left hand turn! Oh and Rusty could help to point out my back asswards think!!!!:tiphat:
