Rebuilt both weber carb's on twin 454 merc cruise engines. Run great. can get 4600 rpm on one engine and 4200 on the other. Weber carb's are very simple. don't know what the fuel pump injector housing is. Looks like two jets to me that sit in the center of the back two ports above the injectors below the butter fly. Not a big issue since I run at 3200 rpm but would like to solve.
