Fuel Pump Question

[MattPSU]

I just replaced the fuel pump on my 72 Cheyenne this morning (350/auto). It ran pretty well, drove it round the neighborhood..no problems. I hop back in and run about 10 miles down the road and it dies. When I was giving it gas it was dying/stalling. Pulled it into a parking lot and it dyed completely. Couldn't get it fired back up. Could it be that there's junk in the line and me replacing the pump stirred it up? Or could it be something else? I hate to have someone tow it and tell me it's just junk in the line. I also hate to have it towed back to my house and not be able to fix the problem. Thanks in advance for any suggestions & help. - Matt

It could be the fuel pump push rod has slipped past the pump arm very rare but have seen it happen. Bad pump from out of the box is possible also.
Fuel filter might be plugged up after changing for one reason or another.

That is all I can think of at this time.

i'd disconnect fuel line from carb and with it in a container turn over the engine and see if it is pumping gas// if it is i'd change fuel filter and try to start it


when yoou disconnected the ffuel pump to change did all the gas in the tank siphon out and you did not notice? and have an empty gas tank

X2 on the fuel filter. I replaced my tank and pump, but not the fuel lines. Got stranded twice with a clogged filter - replaced the lines and no problems since.
