Recently, while running on the front tank, my pickup will start acting like its either sucking air into the fuel line or about to run out of fuel. And it will die, then it takes some serious cranking while cracking an injector to get it going again. It seems to be consistantly acting up like this at/or just under a 1/2 tank of fuel.. but runs fine full. I havent had the problem while operating on the rear tank. It just did it again this evening.. drove most of the day, putting it at around 8 gallons left in the fornt tank, then shut it down for about an hour around dinner time. When I fired it back up it coughed/sputtered and then cleared up. I only made it a mile or so down the road and it started sputtering again.. to the point that it was about to die. Switched to the rear tank and it ran fine. Stopped in at a fuel stop, filled up the front tank, took off down the road and switched back to the front and it ran fine all the way home.

Has anyone experienced a problem like this before??

 

Switch the fuel tank cap and see if the problem moves to the other tank. My 83 did the same thing and it was the cap on the fuel tank.

 

Well that would be a quick and easy fix So, if I read ya right, just take the rear tank cap and swap it with the front cap and see if I experience the same problem while running on the rear..

 

Yep, switch caps and see what happens.

 

The rubber shower head extension on the fuel line that is in the tank could be rotted off, but if that is the case, that usually happens more around a quarter tank left. If this is the case, remove the sending nit and extend the pickup tube with a chunk of fuel line with a V cut in one end, and clamp the other to the steel pickup tube.
