Should have noticed sooner, or maybe I'm loosing it (forget that I am loosing it) but a 1991 454 uses only a mechanical fuel pump, so there should be no electrical connection
You are correct about a 1991 454 using a mechanical fuel pump. This boat had a new engine put in it before I purchased it and has a electric fuel pump and there is no plate for where mechanical pump would go . Would like your suggestion for replacement electric fuel pump. Thank you
