Pulled inline filter off and cranked engine. No fuel. Pulled input line from fuel pump and no fuel came out. I remember when I changed out the pump last year, fuel poured out the input line. This leads me to think I've got an obstruction somewhere. Correct thinking? If so, I plan on disconnecting the fuel line at tank and pump and see if I can get air through it. If I can what's my next step? Pull fuel tank?
Thanks

If so, check to make sure that you have a tight connection at the fuel line at the sending unit. You may be sucking air there. There should be a sock on the end of the fuel pickup pipe inside the tank, preventing a blockage there.

Another possibility is rusted insides to the fuel line. Took a drill motor and a piece of baling wire to the tank to pump line on a '53 one time. Cleaned it right out and never clogged again.ðŸ›

Pulled pick up tubing with float attached from tank. Blew it out with compressor also. Have everything buttoned back up now. Where do I go from here? Can fuel pumps lose their prime? How does fuel get to the fuel pump with the fuel line exiting at the top of the tank? Siphoning action? | | | | | Joined: Apr 2005 Posts: 7,440 Bolter | | Bolter Joined: Apr 2005 Posts: 7,440 | I would not be uncommon for your "new" fuel pump to go bad. Parts just aren't what they use to be.ðŸ›

Fire...die...fire....die. 6th time she took off and is running great. Confused as to what caused fuel line to run dry. Truck was parked on a pretty good decline before she sputtered to a stop right after I moved her | | |
