Iím not sure what the part youíre looking for looks like but if itís a BMW part it is probably Bosch original manufacturer.

Description I see says Bosch fuel pump check valve. Seems they can be hard to locate

I canít see what the part looks like, eBay has two sources one in China and the Czech Republic. The alternate Bosch number brings up a whole fuel pump with it looks like that valve.

I did use it, yes. Spliced into the supply line near the tank at the first rubber line section above the right axle on my MJ. It helped hold the fuel pressure better overnight, held to ~20 psi in the morning. It's still inline.........

EDIT: Damn - didn't realize the check valve pic was so huge. Mods, please delete if possible.

You can also be losing fuel line pressure at the regulator and/or via leaky injectors.

Try pinching off the return line to see if the gauge pressure rises. If not, it usually means the FPR has a bad diaphragm and/or leaky o-rings.

I tried using the ebay check valve once, they suck ass. They are just a small spring holding a plate, and the pressure from the pump is much higher than the spring pressure, so the pump just blows the plate and spring out of the way.

After that I bought a nice heavy brass check valve from McMaster and some flared end fittings https://www.mcmaster.com/#7768k53/=1ac4uo8 I have been running it for a long time, its not perfect but it works well enough. Handles up to 500 PSI head pressure, only requires 1 PSI to open.
