fuel pump – 41240 – production change??
1
I have removed this part from my vehicle (1981 Corvette) and purchased the same AC Delco part for replacement. What I have is two parts with the same number, but are physically different. The pump with the gold bottom is the old pump from 20+ years ago and the silver pump is the new replacement. They are both stamped 41240 (see attached pics). The new pump has a smaller outlet fitting (5/16) and no flare for the fuel line. The old pump has a 3/8 outlet fitting and contains the flare for the fuel line . The new pump is not compatible in its current state for a 5.7L (350ci) SBC . Is there an AC Delco mechanical fuel pump that will match my old pump without modifications?
