question is, where can you put it? who is stupid enough to run fuel lines into the cabin

Hey guys, I've had this problem about 4 times now. Ran out of gas turning a corner. Mine did it at 1/4 of a tank though. I just had the dealer install a brand new 'Fuel Sending Unit' and a 'Sub Sending Unit' under warranty. The whole thing costs $400 without warranty. They also calibrated my gas tank to properly read gas levels. I don't know what they did there. But in doing this, my car tells me EXACTLY how much fuel I have left now. I even decided to run it down til the tank told me I had "---" miles left and I took a hard turn and it seemed to be okay. Granted I rarely get it that low, I just wanted to test it out. If you are still having problems, give this a try. I haven't tracked my car yet but it's way better driving on roads now.

Yeah, but I've gotten to where I can't run longer than fifteen minute sessions before it happens to me now.

It all depends on the tires. On street tires you are okay for 20 minutes, on race tires the extra G loads pushes even more fuel away so it happens sooner.

15 minutes was on AD08s at VIR and about 20 minutes at Barber

If I recall correctly, I started getting fuel cut 2-3 laps into my second session at VIR. I am on stock suspension, maybe that helps as I can't pull the same G's.

With the in-tank pump setup from nothotwire, I am able to run deep into my third 15-20 min session now before I get any cut... with hoosier slicks

I wish that kit was available for you guys!

Yeah, I never heard back from him, but I'm talking to others about a solution

I am very happy right now.... we have this issue taken care of... we had a project in the works for a really long time, and then just the other day had a total stroke of genius on an even better way to solve the problem. within a couple weeks i will have it all ready for you guys with test data. it is awesome, its almost plug and play, and its all concealed within the factory fuel tank.

phunk 07-21-2011 08:28 PM

actually planning to build 4-5 more of them this weekend, so could be available as early as next week

Sweet! Paypal at the ready!

why dont they just do something similar to aircraft and make the tube exiting the pipe have a venturi effect and have a low pressure high velocity point in the tube leading to an extra pump that is connected to the fuel tank that will increase the chance of fuel starvation and maybe save a little on weight depending on the size of the suction tube. idk just a thought.
