Fuel starvation, who else?

Don't quote me but I believe a member here (TravisJB) had done this. But only mild results from it. Can't remember.

Correct. My car had a combination of fuel cell foam and pickup pumps on drivers side and rear drivers side of tank.

The foam will control 'sloshing'... but I believe it will not control the fluid angle that occurs in a sustained right hand turn. Foam is not a solution to our problem but may help just a bit in certain situations.

I'm hoping that Doug at Z Fever gets on here soon to clarify how his fix is coming along.

^very interested in this. Travis were you also running the second fuel pump from the drivers side to feed the pot on the passengers side? I'd so how did that work?

travisjb · 05-13-2012, 01:27 PM

Yes, I had a second and third fuel pump that fed back to the OEM pump. I pulled those out for safety reasons... they were getting hot when not soaked in fuel, ie when turning left and I didn't want to risk it... the other problem was that those secondary fuel pumps were not mounted they were just held down by the foam... they were bumping around a lot... the solution z fever is putting together will use a second pump but it will be soaked at all times I understand, and so less risk. The secondary pump will mount in the secondary access panel and will be integrated with an in-tank swirl pot... one simple unit that then feeds back over to the OEM pump, as I understand it.

In any event, I'm going to refrain from discussing it further until Doug can come in here and explain for himself. It's his product, not mine.

Ok sounds great and simple.

Anyone know if it's possible to simply swap the OEM pump and secondary sender from side to side? Won't fix the issue per se, but it would mitigate it due to the fact that the vast majority of tracks run clockwise.

the only certain fix that I know of is what jayfightmoves did and its a little extreme, plus you lose the fuel gauge. He took the tank out, cut it in half and welded the one side shut and just put half a tank in the car.

travisjb · 05-13-2012, 09:42 PM

^ damn, not a bad idea for my car... but wait, what materials is our tank made out of?

Mike · 05-13-2012, 10:40 PM

aluminum, I think.

Ridiculous.

never say never.

i have a brand new tank from nissan sitting on the floor here, and its definitely steel! Very easy to fabricate on. For those of you willing to fabricate on to your gas tank, I see no reason to go so far as to just cut the tank in half and weld it shut to keep it that way... if you already have the tank cut in half, just add proper baffles and trap doors and then weld it back together and retain full tank volume.

Christ, maybe that's the best solution here... someone create a program where they offer modified steel tanks... if a core exchange is included, maybe it would be the cheapest and most effective fix to our problem???

phunk · 05-15-2012, 11:14 AM

^^^ thats a pretty labor extensive route.. I believe much more costly than a good surge canister setup. But, it does solve the problem at its very ROOT, which I am a big fan of doing.

For those who havent caught my thread about it... Fuel Starvation Control Product

We are now entering production on the solution we have tested by the Performance Motorsports team. I posted over there about it to get a head count for people in for the first batch. Production will begin in a day or two and we are trying to determine how much material to order for some of the parts we dont have the billet we need in stock for. I put all the details I have in that thread, those who sign up will get more specific details via a mailing list.
