Clois,

Based on your description, I am wondering if your problem is not on the pickup side. I think most fuel pumps do not like negative suction pressure. Therefore, if you are putting a filter on top of the tank, I assume that the pump is also up there. Therefore, under some track condtions when you have mediocre fuel levels over the pickup in the tank, the pump may be starving. What type of tank are you running and where is the pickup. A SCCA racer friend used two pickups in his fuel cell, right and left, with two fuel pumps just to avoid this problem. Even then, he was very careful to inspect the fuel pump inlet screens before practice sessions and races to ensure best possible fuel flow.

Is there any way to mount the pump down low at least level with the tank and then move the filter on to the pressure/outlet side? Can your pickup inside the tank be modified to ensure best possible conditions when turning and accelerating?

Regards and good luck,

Gary
