loss of prime
I did some searching and did not find anything that really answered my question, so I am hoping that the knowledge base of this forum is better than my search skills.
I have had a repeating issue regarding my truck dying after shutting it off when hot. The only way to get it going again is to manually prime the fuel system at the filter. By my thinking, I have to have a air leak into the system that is allowing air to be sucked back into the system once it is shut off. I have changed the fuel filter and made sure it is seated, but this problem continues to crop up.
I have always been able to get the truck running again, but having to prime the system everytime is getting really old, and my wife obviously refuses to drive the truck.
Any help would be greatly appreciated.

It is only after the truck has been running and up to operating temperature. It will generally start up but die withing 5-10 seconds after starting.
Once I go through and manually prime the system again (at the fuel filter housing) it will generally start right back up, sometimes it takes a couple of tries.
Once it is running and as long as I do not turn it off, it does not quit.
Again, I appreciate any and all ideas that anyone would have towards getting this issue resolved or at least giving me an idea what to start with.

i would check if you are leaking fuel past the pressure relief valve.

also double check that there is no air leaks on the filter housing. the bleeder screw is a common source along with the primer bulb.
with the engine hot from just running, when it would normally have this problem, try priming it till the bulb is hard before attempting to restart it. if the engine starts and runs fine without dieing then it is likely an air leak in the fuel line.

Thanks for the replies. The fuel filter housing appears to have been the problem. Unfortunately, I was out of town when my wife needed to use the truck and it died on her. I just had it towed to the dealer and had them replace the filter housing. A little more expensive, but no more stranded wife and no problems since. Again, thanks for your insight.
