460 running parched
I am convinced the dentside gods have placed a curse on me. I can't seem to get any fuel out of my fuel tank. I put in a fresh Holley mechanical fuel pump, new AN fuel lines, Brand new fuel tank, and a new fuel sender. Prior to putting in the fuel lines I cranked the hell out of the motor so maybe the fuel pump was workin extra hard. I have no idea what to do now. Anybody got any ideas?

A couple of tests might help track down the problem. 1) priming the engine with ~1/2 teaspoon of gas down the carb 2) run from a can. Submerge a length of rubber hose in a gas can and hook the other end to fuel pump inlet. See if she runs that way.

Ideas? Yupp...
Disconnect the fuel feed line at the fuel pump....the one from the tank, and empty it in a clean container. Have a helper put some air in the tank at the filler cap and cover the hole with a rag - not too much air - about 10 psi or less and observe the container.
Got gas?
If yes, reconnect everything and disconnect the fuel line at the carb's input....again putting the hose/line in a clean container. Crank her over and observe the container.
Got gas?
Hook everything back up....peek down the venturi while blipping the throttle. Should see a coupla squirts of fuel shootin down the throat. No? Accelerator pump time....Yes? Make sure you have spark at the plugs.
If no, recheck all the fittings/connections for tightness...you don't want to be sucking air through the lines....if the lines are what diameter - 3/8"? Recheck with air.
Got gas now?
Repeat the above disconnection to the carb........etc.
