Are the fittings on the pump marked at all, ie "inlet" and "outlet"? If you disconnect the line at the carb end and crank the engine over briefly, does gas spurt out?

In the pictures your fuel fitting lash up appears correct. The hoses look sketchy, could be sucking air but with no drips maybe not. Is there gas in the tank? Is the fuel selector valve oriented correctly to the tank with gas? As in the previous post, try cranking with outlet line disconnected. Are there any instructions that came with the new pump?


I have two suggestions. 1) cap the vacuum pump fittings on top of the new fuel pump if you are not going to use them. Then plug the connection to the intake manifold. It will be a potential vacuum leak if you are not going to use or need it for vacuum wipers.


2) Your new fuel pump has no sediment bowl. You might be able to fit the bowl off of the old pump on to it, but if you are not going to have a bowl, at least get a fuel filter on the inlet line to the pump.

Thank yíall for responding so quickly.

Scoutboy 74, after disconnecting the carburetor side, gas does not flow out. The fuel pump is labeled and I believe I have it hooked up as labeled.

Greg, There is gas in the tank. I have decided to change the hosing. Itís so cheap I would hate for that to be the problem. I have two in-line fuel filters: one before the pump and one before the carburetor. No instructions came with the pump that I bought from IHParts other than report problems quickly or you donít get your money back. I only use one tank so my fuel line completely bypasses the selector switch. Itís just one straight line. Iíll send a picture of that when I get home in two days. Iíll also plug up the windshield one like you suggested and see how it goes. Hahaha. Iíve been thinking about taking those off anyways.

Thank yíall again for your help. I wonít be able to respond for two more days, but Iíll definitely let yíall know how it works out.
