This is for my VR6 passat. I am having a hard time finding a source - either OEM from another make or an aftermarket universal. I have had two fuel pump check valves fail at the une fo 250+ for a new pump each time. I would rather install a one-way valve near the fuel filter or even near the rail to keep the lines pressurized...

Anyone havea good source for this sort of thing?

Thanks!
