Thanks for getting back so soon, first year for the 24Valve in Dodge P/Us , that's where my experience lies. Carefully filling the filter, plug the center hole with your thumb, as you slowly pour the fuel into the outer holes; this way all the fuel you put in goes through the filter membrane and particles don't get into the very expensive VF-44 injection pump.
I'm assuming the filter housing is on the side of the engine ?
Have you looked for any kind of pre-filter on the frame?
You can do, a dry filter install then 3 cycles of the ignition key , the electric lift pump will run for 18 seconds each cycle. Then start the engine.
But I've heard of problems with this method and the factory filter head on the P/Us has a bleed screw , 10mm, wrench size that is loosened to allow the air to escape; and it's the fitting for lift pump testing.
If you have a frame mounted filter it must be pre-filled, as the lift pump is on the side of the engine and won't pump the air out of the filter.
Best bet; pre-fill the filter & do the key cycle.
If you go to your " User CP" opposite end of the blue bar from your " Log Out" and on the left side of the page click "Edit Signature " you can enter your coach info , and have it automatically appear below your posts, and you won't have to type it in every time.
As mine does below.
If you have any problems with the start up, let me know and I'll walk you through , bleeding the injectors.
