if ur talkin about the one in the engine bay i already changed that… im pretty sure thats the only fuel filter except for a screen by the gas tank but i’ve been fiddling around with this “fuel check valve” and it makes all the difference whether the car will start or not … like when i move it around n stuff…

its prob another filter. Anything that would be like a cheak valve in the entire fuel system would be the pressure regulator on the side of the fuel rail.

Explain the problem.
