Hello and welcome, I am by no means the expert on this but here is my 2 cents... I have been running the 32/36 for about 5 years on the stock fuel pump and NO FPR (Fuel Pressure Regulator). It sure sounds like the float is sticking? I don't see you mention that the Fuel filter was changed? Someone else should chime in with other options. Good luck.
