Fuel Flow Issues
While working today my 69 C-10 sputtered and wouldn't start. I checked fuel flow to the carb and as suspected there was none. So I assumed it was a filter and pump issue so I bought a new filter and pump and still nothing. I checked to see if any flow was going straight from the pump to carb and nothing. In fact there doesn't seem to be any fuel coming from the tank. Should I be thinking of a clogged filter in the tank?

Re: Fuel Flow Issues
If it's an original tank there is a screen type filter on the end of the pick up line that could have sucked rust or something else to it possibly.. I've heard of even the screen itself deteriorating. Oh, and make sure your gas gauge is working.

Re: Fuel Flow Issues
I had ton of fuel flow issues last summer. Usually the fuel would empty out of my line from my pump to the carb. It was most noticeable after the truck sat for a while. I changed the filter, all the lines from the carb to the tank. Drove me nuts. Finally changed the mechanical fuel pump. Seemed to cure my problem. There must be a valve in the fuel pump that maintains positive fuel pressure to the carb and mine must have been broken. Good luck with your issue.

Re: Fuel Flow Issues
Check the rubber hoses that go from your tank to your fuel line and your fuel line to the fuel pump. I spent a fair amount of time chasing a fuel delivery issue a few years back on a 1974 Ventura... filter, then pump, then sending unit. The rubber hose had hardened and cracked enough to suck air, but it didn't leak gas.

Re: Fuel Flow Issues
Good point, The alcohol in the gas now tends to cause older fuel hoses to deteriorate pretty rapidly. Also if you don't have a filter between the tank and the mechanical pump there is a good chance that there is something stuck in the valve (s) of the fuel pump which are little flat check valves with light springs behind them and a piece of sand stuck between the valve and it's seat will keep it from working.
