Testing a fuel pump on a '62 slant-6

9384 Views 8 Replies 5 Participants Last post by  Scrounge
I've let my 62 sit idle for many months and its time to get it at least running. It turns over fine but I had no ignition or discernible fuel at carb,, I added many gallons of fresh fuel, still nothing, so disconnected the fuel line between pump and carb and am getting nothing.

Any tests or actions I can do before yanking the pump?

How easy it will it be to rebuild or replace the pump?

Disconnect the line below the fuel filter to be sure that's not clogged.
Replacing the pump is easy, except access is not great. Disconnect the fuel lines in and out, and then the bolts holding it to the right side of the engine. When installing, be sure the pump arm is riding on top of the camshaft lobe and not under it. This would break the pump arm and possibly the camshaft. To avoid this, after installing the pump, turn the engine by hand and see if it binds at all.
In addition to what Bob said, it also only takes a pinhole in a steel line, a cracked rubber line or even a loose clamp to make the fuel pump suck air instead of gasoline.
