Hmm, my friend just sent me this interesting TSB, which could be the source of my problems with straight-line acceleration!

Admittedly it is VERY possible I may have not installed it 100% correctly.

Fuel pumps seem very susceptible to minor installation errors that could/would only present under certain (rare) circumstances.

As I've said before, it is also very likely that this issue was vastly worsened by the fact that I was running high boost on E85.

For my last autocross I switched back to 93 octane and lower boost, and topped off the tank a mile from the event site, and had absolutely no problems with fuel starvation. I don't remember how low the fuel got, but I had a codriver, so I think it was down to 3/4 of a tank by the end of the day (about where I was last time), and still had no issues.

I'll continue to monitor the issue and update with any other findings.

When fuel is low, coming out of turn 2 onto the braking zone for T3 (at Thunderhill), my engine died from fuel starvation. I just downshift for T3 and popped the clutch to restart the engine.

BTW, I just installed the DW pump last weekend. I noticed, if you use their universal kit, the suction is about 1/2" higher than the stock location. I opted to use the stock filter suction thingy as it is lower.

I just swapped back in my OEM fuel pump for my track session last night. I was carrying much more speed through the main left hander and running the car with just under half a tank. No fuel starvation issues at all! I think it must be mostly to do with the different size of the socks on the OEM vs the Aeromotive.

Im all stock in the fuel area right now...car has been getting progressively worse. Now starves for fuel at anything less than 7/10 tank. Such a pain.

I have been fighting this issue for years in my car.
anything less than a half tank and I would get starve in corners.
I modified the stock tank pot by adding a hole in it which I dont think did anything.

At my last race in Oct last year I installed a swirl pot and did it wrong so I had fuel starve worse than before.
about 1/2 way or so through the race the motor let go
I have not installed a 15 gallon Fuel Safe cell with collector in it and the return will dump back into the collector.

here is what it looked like from my perspective

Granted I was supercharged and using almost a full tank of gas in a 30 min race so the amount of fuel needed was way more than a stock or NA motor.
