PREDATOR 670cc PREDATOR MOVE BACK TO DIAPHRAGM FUEL PUMP

Hard choice, after all the work to change the carb and the fuel system from tank to carb. The last video had a bypass filter to reduce the fuel pressure from the electric pump. Another tuber said something that made me check the numbers on the pump which was supposed to be a 1 to 1.5 PSI. Turns out to be 2.5 to 4 psi me got sold a lemon!!!!!! I pulled the electric pump, filters and return pipe work, then ordered a diaphragm pump and re fitted almost in the original position. Still a little warm blooded but the pulsing is down a lot. The saga continues....Moral of this story make sure your pump is 1 to 1.5 PSI MAX PREDATOR 670cc PREDATOR MOVE BACK TO DIAPHRAGM FUEL PUMP
