Replacing fuel pump on 69 340

all of the above but i haven't seen when putting a new one on i always like to put a filter before and after the pump,replace all lines ,on my aspen the mounting surface was cleaned but the hole had built up crud so i gently wiped it off without any falling in the engines and i put a Lil more grease on the moving parts of the new one they kinda skimped on it.

i don't even worry about the alt there i disconnect the battery tho
