Truck Box / Bed Removal

I've got a weeping fuel line and I think the only way to access and replace it is to remove the box off the truck. My Haynes manual simply describes it as four bolts and disconnecting the wiring harness for the tailights and licence plate light. Then (with a few friends help) lift the box off the truck. Surely it can't be that easy!!

Anyone out there ever tackled this job? I really don't think I can get at the busted fuel line unless the box is removed. Thought maybe while I had the box off I could check and rustproof a few other items.

What do you think?

If you can get the rusty bolts loose and get a few buddies over to help get it off, do it. It makes it alot easier to fix fuel issues. I've done it this way for years, however I use my engine hoist, but the buddy system is effective.
