O.K. first thing to do is get a gas tank with a hose hook it directly to the carbuerator (both need to be clean with clean fuel)so it can gravity feed the carb. Start and run the engine. Then hook it up to the intake of the fuel pump start and run the engine. Then hook to up to the fuel filter start and run the engine then hook it up to the first joint after the tank pickup and start and run the engine.
Where ever it stops thats your problem.
I remember once on a 33 bert, where I brought a guy a fuel pump, the mechanic hooked it up and it still wouldn't go. He said hold on and ,get this, goes to the fuel pump the one you get your fuel from at the marina. He turns it on sticks the nozzle in the carb and says fire it up which I do. He keeps the engine running by squeezing the handle of the fuel pump nozzle and moving the throttle butterfly LOL.
He then says ok tell me if the fuel pump is pumping air out of the intake. I feel for the inlet to the fuel pump and sure enough its pumping air out the intake. He swears under his breath grabs the fuel pump mumbles something about those idiots and walks off. About ten minutes later he shows back up with the same fuel pump reinstalls it and says try it now, a turn of the key and it fired right up.
He says that the fuel pump was set up backwards and that he has come across that from time to time. LOL He was about 50 dark blue very dirty cloths and dirt under his fingernails probably been there for 5 years. But he knew his stuff this whole thing once I arrived on scene took only about 1hr and 30 minutes total. If I remeber correctly this was manasteec MI, a very small town on Lake Michigan.
