How and where do you bleed the fuel lines. my truck is still screwed up but i want to try this. then some injector cleaner in the tank, and then a new fuel filter.

is the fuel filter on the side of the engine on the passenger side?

where is the bleeder valve??

Yes the filter is on the passenger side back by the firewall and battery. There's a big round metal cylinder on top of the housing, thats the primer button. Towards the engine is a black screw with a little hole in the top, thats the bleeder screw. Open it up a ways with a screwdriver and pump the metal primer button a few times. A steady stream of fuel should come out. If there's any squirts or burps or anything, then that means you have air in your lines. Keep pumping until a full pump of diesel with no air comes out. After that, close the bleeder screw and start the truck, see if your condition improves

No problem! here's an old fuel fitler change DIY write up with some pics that should help. It's not exactly the same for your LMM, but the fuel filter housing will look the same.
