Fuel starvation on track

[2morrow]

Does anyone have experience with the KPM pump?

This seems like a much easier/cheaper option than GT-350 fuel system conversion.

NO! These cars burn enough fuel on track that it's hard enough to keep up with fuel levels. I purchased the 1000HP pump because it was the smallest one available. The 800 HP (which should be plenty for most folks) was not available yet. It's a quality set up and so far completely trouble free.

@VictorH I posted on this before but we actually measured the factory pump and bucket venturi-induced filling rate and found it to be 363 lph at 70 psi fuel pressure. 363 lph will support way more than 460 hp. However, the 363 was a combination of two venturis, one pulling from each side of the tank. On a hard turn either way with low fuel, one side could go empty and it would rely on a single venturi to fill it. Even still, a single venturi flow of 182 lph should still be sufficient, though not by much. It is possible that the venturis don’t split the 363 exactly and perhaps that’s why you see the issue.

Either way, I do think kpm is the only company that actually makes a solid engineered bucket comparable to stock but better. I just wish they’d include a proper filter.
