The gases we have today will go bad much quicker than it used to. You can even add some fresher gas to what is in the tank to help if it does run on the outside tank idea. Fuel pressure is low or the filter is clogged. Also since your probably gonna have to rent/borrow a vaccum/ pressure gauge[ you can test both vac and pressure with it]after you test your pump to verify its worthiness then put the gauge on the manifold side of the vaccum [down under where the throttle blades of the carb ]and test that. If it is running a little while and then smothering it could be an exhaust obstruction. Or best yet go to where the pipe comes out at and feel for exhaust before the truck dies.if you get none you have something blocking the exhaust pathand that will also smother the truck and kill the engine. Ever hear of the potato in the tailpipe gag? That is what that is for. If indeed that is the cause don't run it very long, it is very hard on the exhaust vales and such to do a motor like that. You don't like being backed up do you? Jim
