I was racing my Exige Cup 255 this past weekend and experienced fuel starvation under WOT in 3rd and 4th gear. Car kept running and I was able to blip the throttle and get it revving again, then a few laps later it would reoccur. Fuel tank was full at start of 25 minute race and this occurred relatively early in the race. Water temps were fine. Feedback appreciated!

I think earlier fuel tanks had adhesive around the baffle degrading over time and clogging the fuel pump filter...
Proalloy makes a good aftermarket one, as well as an optional large capacity one.
And of course, BOE and Radium makes a standalone fuel surge tank.

Thanks - I found another good thread on this with similar recommendations. I also just learned that my car has a Lotus Motorsports baffled tank so shouldn't be doing this so we're going to check fuel pressure.

Sounds like you might a good candidate for a surge tank or upgrade the in tank from 190 oem to a 255 Walpro
