“They then installed a Fuel Pump Cycle Control Module Kit, GM Part #19167115 and the truck started and ran just fine. My undertsanding is that the filter is an intergrated part of the fuel pump and that there is no in-line filter to replace.”
End of story… It would seem THIS was the problem right from the get-go…Forget the lawyer. And yes, there is an external, in-line fuel filter. The in-tank filter is just a sock/screen that lays flat on the bottom of the tank and acts as a fuel pick-up…
