Bleeding Air From a 24 Valve VP44??

[WileyCoyote]

I ran my 2001 HO out of fuel the other day due to a bad sending unit in the tank.



After this experience, I suggest that no one ever do this. It is really bad news!



I tried to bleed the system loposening the banjo fittings on the VP44 for fuel inlet and return. After lots of bleeding, the truck would still not start.



The local dealer bled it and now it runs fine. The question is where can I find the best procedure for bleeding a VP44 that has been run out of fuel?



Thanks for your help.

I believe you loosen the 3rd injector fitting on the head---someone correct me if I'm wrong----chris

Crack open the line to the VP44 and run the lift pump till the bubbles stop and you get clean fuel.

Then you need to back up two or three of the outter injection lines from the head and crank till fuel appears. Tighten the lines up and go for main ign. It will start on one or two cyls at first then smooth out.

HVAC got it right: been there done that due to failed sending unit. #@$%! #@$%! #@$%! #@$%! #@$%! #@$%!



I carry a 3/4" wrench under the back seat now

A 19mm wrench is what I used.

Me to now



I now have an 88 gal transfer tank in my bed and my main tank does not get below 1/4 tank and I fill it back up.



Never again will I let my truck go dry. There is a long story behind what it took to get my truck and tractor home that day. My buddies still get lots of from it.

Same thing happened to me, bad sending unit. The proper procedure for bleeding the air, same as what HVAC just said above, is in the big service manual. If you don't have one, get one. It's a fantastic source of information. Not good to be without it. I just happened to have mine with me when I ran out of fuel. It saved my butt.

WARNING ! Do not over-torque the fuel line fittings! Traveling with the manual, a 19mm crowsfoot wrench, a torque wrench, and various other tools will definitely give you a chance of avoiding towing fees.
