That fuel filter is fully serviceable, the tank on the other hand need full R&R, I’ve done what seems like hundreds.
the real issue is injection pump and check valves…
YES to all of that and more.
My post is to simply show what can be going on in the tank. Thinking it thru to the whole fuel delivery system. One would not want crap (maybe beer) flowing thru one blood system... so just pointing out what can be lurking in the tank and shut down that NU to U HumV. Take the time to do it right and PMCS before that first test run turns into a... POS and more $$$, time and frustration when it should / could be FUN.
Sung to "Dem Bones" with a twist.
Tank connected to the pick-up, pick-up connected to the check valve, check valve connected to the lift pump, lift pump to the fuel filter...... By the time one gets to the Tail Pipe verse... pretty much covered it.
Funny song , BUT just got off the phone with a customer with a no start... having gone thur the whole system. (not funny)

Not in the TM's but could be helpful. Insert part names as needed. Work in all cases. LOL
When was that PMCS due ?
