i didnt replace the return line from the pump to the tank. it didnt comt with anything to replace it with so i never took it off. it uses the stock return line.

 

Still may be bad if it sat that long. If that valve is rusted or stuck in the open position it creates the same problem.

I may be way off base here on what is creating the noise but this sure would be the easiest and by far the cheapest thing to check first. If your truck runs for a while and then dies it almost has to be something fuel related. Most anything else would keep the truck from running right at any speed for any amount of time. Have you checked for codes and do you have a fuel pressure gauge to know what pressure it's holding through all of this.

 

no pressure gaugecheck engine light hasnt came on.
it runs great sitting still. even at wot it does. it only dies when i trie to drive it.

 

Gotta be fuel supply.

 

so you think the airdog is messed up somehow

 

Pretty unlikely but can't answer that without a pressure gauge.

 

im gonna trie to get ahold of one tommorow along with going ahead and swapping the IP out

 

good luck to ya. Just for informational purposes. You can have codes without getting a check engine light, happens all the time. If you get a gauge be sure to get the cheap mechanical gauge.

 

i know that just aint got a scanner to read the codes on mine. i will borrow a scanner tuesday if changing the IP dont work

 

Id try and get a scanner and a fuel pressure gauge on your truck before you replace your $$$$ VP44.
