While you have the tank out, remove the filter and use an air hose to blow any and all crud and old fuel BACK to the open line from the tank. Shouldn't be any crud but can't hurt to check, dump that fuel! It's not worth saving, replace it with new clean fuel and dump that old crap in with some oil for recycling. To help purge all the air out of the empty fuel lines crack the line loose at the fuel pump and after putting the new fuel in the tank use a blow gun and some rags to apply a few PSI into the tank, that will force fuel up to the pump eliminating a lot of air. Use soldier #2 to watch for fuel at the loose fitting. This saves a LOT of cranking on the starter.

I did blow out the lines while I was replacing the lift pump but I like your idea of air in the tank to pre-prime. Thanks.

I finally got the tank from LMC. It actually showed up pretty fast but took me a few days to get back to the shop to install it. I got it in, bled the lines and it started right up with about 5 seconds on the glow plugs. I have not taken it for a spin yet but I am hoping that this finally fixes the issue. My gauge is now working too. Win - Win!
