Default Check valve-89 A4

Where is this check valve in the fuel pump area? Changed the pump out the other day and it didnt occur to me at the time to look for it and test it.

Anyone have a pic?

So it's new pump time in order to fix a bad check valve? Nice!

Yes, BUT! A defective check valve isn't a serious fault. All it does, is allow the fuel to drain or depressurize back to the fuel tank. How serious can that be? The only disadvantage can be slightly extended cranking time.

RACE ON!!!
