I am having problems with getting fuel to the carb. I have changed the fuel pump, filter. Blew the lines out. When I first start the truck the lines and filter fill up and will idle if choked. When I press the accelerator it empties the line and filter and will not run.

 

Check the rubber fuel line that goes from the frame to the fuel pump, have had them leak and suck air, thus not delivering enough fuel. If you have the old fuel filter that screws into the carborator these become cloged and not enough fuel to carb bowel to run truck. Its a good idia to replace it even if you can blow threw it, the filter that is. I have poked them threw with a scew driver just to get me home when they become cloged.
good luck.

Thanks for the reply. I will check the line to the fuel pump. I didn't think about that, because I took the output line off the pump and it pumped gas to the inner fender. I have changed to an inline clear filter. I will check all the rubber lines.
