I replaced my failed rebuilt fuel pump on my 1973.5T/CIS with a new Pierberg unit, but was not sure about a check valve. My old pump had an internal check-valve according to the manufacturer. Do "banjo" type fittings act as some type of check-valve? Everything I have seen thus far as the actual check valve requires a "banjo" attachment. I cannot locate a direct-in-line unit unless I am looking at the wrong place.
Anyone have a photo and/or source for an in-line check-valve? What am I looking for? On the CIS pump located in the rear left wheel well, would I want the in-line check valve after the tank and before the pump or after the pump before the accumulator?
Thanks
