Posted April 15, 20241 yr I'm replacing my fuel lines and found a capped banjo fitting on the intake of the stock fuel filter housing. It looks to me as if it were brazed shut. Any ideas as to what it's there for?
April 15, 20241 yr I would suspect it was there for a lift pump fuel pressure test port or for an in-cab lift pump fuel pressure gauge / warning light system. - John
April 15, 20241 yr Author I guess I was kinda thinking the same thing. I do have an in cab warning might that runs off a T in the fuel line between the factory filter housing and the vp44. But it evidently doesn't work as I found today that the ground wire isn't even hooked to the sensor.
