Who here has installed an external check valve on their fuel supply line and if so, what brand, p/n etc. did you use ?
I replaced my pump last year due to a failed check and also as a pm move. I used a Bosch so the quality shouldn't be in question (ya right), well it has failed again.
I pulled the fuel rail with the injectors intact to verify the pressure drop was not due to a leaking injector.
I don't mind changing the pump again but if this is going to be an annual thing, than I do mind.
Side note: The interior of my fuel tank did not have any debris when I replaced the pump.
