Default Replacing my LP

I'm replacing my LP, will I need to crack my injectors to get the air out? Also, if I replace my overflow valve at the same time, will I have to crack an injector line also? Any tips, or trick I might need to know on these, I'm new to the 2nd gen 12v

Thank you for any info, it's always appreciated

Which ones do I crack, and should I have any troubles? Should I just go with a Raptor or something instead of the factory replacement? My 95 will prolly always be stock. It's my DD, and I'm all about the mileage.

stock pumps on those trucks are plenty even for mile upgrades so save the coin, which ones to crack 2-5 are fairly easy to get to and will let the truck start, it will just idle rough for a few sec untill the other 2 cylinders self bleed

Well that was a crappy job. It took my 3 hours to replace my overflow valve, and my LP. That LP was a b@tch, my fuel line was just a hair too long(from the factory) and fought me the whole time. The bolts didn't seem long enough at first, couldn't get them started, not to mention the F'd up position that things in. It was just a b@tch, and if it EVER goes out, I'm going with the Raptor, and some other fuel filter. I guess I could of removed my fuel filter, but that fuel line being just a hair over sized was a pain. I did go through the wheel well, some dude said he put one on from top side, I don't see how, I'm just complaining.
Just saying... I thought it sucked

if you throw out the old bolts and get studs, it make the replacement so much easier.
