fuel pump for carbureted (OE part)

Due to the age of your truck, it's a good chance yours has been replaced before. Sadly, it was probably with a sub-par "parts store" unit. Diaphragm leaks either internally into your crankcase and thins your oil or it leaks external creating a possible fire hazard. Neither is fun. 

Your carb needs the proper fuel pressure to run correctly. 

Includes both gaskets and the spacer plate. 

OE part, never chinese counterfeit
