1977 Tricabin Fuel Pump
I am searching for a replacement fuel pump for our tricabin but I am having no luck. The visible numbers on the pump itself are as follows: 603903 d28a. It is a carter fuel pump the engine is a '77 5.7 or 350 GM. Any suggestions?

What Paul said ++
A marine FP will have a hose barb for a clear hose running to carbie, incase diaphragm should break fuel will go to engine and not into bilge and or engine crankcase.
I replaced mine on my tri-cab with 270 crusaders with not problem.
