So get a new filter just in case. Is priming it a challenge once I sort out the leak

You can crack open the filter top n t valve and jump a power wire to the LP to purge the air out. Saves alot of cranking but probably not necessary.

Of course purging the air from the filter is needed.
otherwise it would take an obscene amount of cranking to expel the iar.

I also like to crack an injector line loose to speed up air removal and have a quicker start.

beware of moving parts after the truck starts when you tighten the loose line back up.

What I meant to say is that the jump wire probably isn't necessary . I think their's a couple easier ways to get the LP to run. I always forget and fall back on the jump wire.

The easiest way that I know to jump the LP is to place a heavier gauge wire in the G terminal under the dash to the positive terminal on the drivers battery
