ok i will try again, but i see no fuel coming from tube, last month when i tried to do the same thing fuel came out almost immediately, worst case scenario will drop tank replace sending unit clean and maybe replace tank and replace mech fuel pump ????????

repeat.... takes a while if you let the fuel "drain" all the way back to the tank.....
air doesn't pump out that fast....

If you want... AND YOUR CAREFUL....... put a little pressure on the fuel tank while doing the prime... stuff rags wrapped around air hose into opening....
maybe 5 lbs.... it will help move fuel in the right direction..... just remember A LITTLE IN THIS CASE IS BETTER THAN A LOT!!!!!

I went to the farm feed store, bough the largest syringe for horse vet shots, The end fits snuge on the plastic hose, I pulled the plunger back, crimped the hose, removed the syringe, closed it up and withdrew a full syringe of air, remember to take of the fuel cap off to let air in the tank. and it may take a while to pull all the air out of the system, better than running down your battery with cranking. Remember to get your engine warm first, before removing the fuel filter then unplug the pink wire untill you have all the air out. Then Crank untill you have good fuel flow, pug pink wire back and start.

Great guys good idea from both last replys will try this weekend again, will try to vent tank ans add pressure to 5psi and crank longer...thank you, thank you very much

if you have one of those hand vaccum pump brake bleeders or a vampire pump they work great for removing the air from the fuel system.

how and where do you use it? I'm new to cucvs, bro thxs

I am still having issues with air getting in the lines. The easiest way that I found to push the air out is to put an air nozzle on the breather tube coming from the tank and then have someone else crack the fitting on the top of the filter. Once the air is out and you have a steady stream of fuel you can close the fitting.

One thing I have noticed, and it may be a coincidence, but when I park the truck uphill, the truck with start and then die about 5 sec later. I suspect the fuel is running back to the tank but am not sure. Has anyone seen this?

Note: truck will start fine when I park downhill.

Any advice/help would be appreciated.
