Must be nice. I have to top off after every session.

Not enough room forward of that bracing, up against it, with all the interior gone?

I'd imagine he'll run a proper fuel filler hose out to the stock gas door location. Other than when working on the fuel system itself, it should be sealed all the time in the interior and not leaking/splashing/etc

I just want to say what a great product Phunk has made. It's helped me tremendously...

...in my wildest fantasies. The only thing worse than having no good solution to a problem is having someone dangle magical carrots in front of you and never deliver.

Ridiculous.

Maybe it's just me but on my 2012 I don't hit it until I get to 1/2 tank. Been tracking at bigwillowspring and button so there's tons of long right hard turns.

FYI....we removed the OEM saddle tanks and replaced it with our own Doran design fuel cell and it is a return system.

So, on the first page of this thread (2+ years ago) someone suggested fuel cell foam. Has anyone tried/investigated filling the left side of the tank with fuel cell foam, or creating a barrier in the middle of the tank with fuel cell foam?

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

travisjb · 05-13-2012, 10:40 AM

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.

SPOHN · 05-13-2012, 11:23 AM

^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, 12:27 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.

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.
