Just unplug your tail lights and remove the six bolts ( or eight if its a long bed)holding the box to the frame. Then move the box about two feet back on the frame. You will need help moving the box ( four people works the best).Done this a dozen times or so. Sure beats trying to drop the tank.

Yeah I would definately take the time to lift the bed rather that cut a hole. Ive had to do it on my good ole Dodge and even being pretty dirty, with a trusty impact gun, the bed came off pretty damn easy. Plus you get all the room in the world to work, not just a little hole to stick your hands through. Not to mention then you wont have to stare at the hole/welds from patchin the hole the rest of the time you have the truck. Lure some buddies over with a case of beer and lift the bed off, its not that bad and it will be worth it.
I had the box off my 99 silverado e/c this past summer and I was fortunate in that all the bolts came out but if you decide to go this route FIRST start the bolts with a breaker bar/strong arm rather than an impact.If you use an impact to start them you run the risk of snapping them off is they are the least bit weak,at least this is the advise I was given and is what I did and it worked for me.
As far as the # of bolts my short box had 8 in it not 6 but where yours is a 93 I'm only guessing it would be the same.

I agree with the breaker bar point, I actually did the same. Also a day or so before I soaked the bolts with some kroil (rust penatrator) an I think that helped me out quite a bit as well
One thing to remember about pulling the bed. If the bed bolts are painted, you'll lose the seal the paint provides and can expect future corrosion under the bolts. I suspect it isn't an issue with you since you were thinking of cutting into the bed floor, just something to consider.
I've done plenty of Fords this way (usually on test trucks) and suspect your chebby wouldn't be any different. No dirt/rust in the eyes and no need to drain the tank or worry about clearance getting the tank out from under the truck.

i own a auto shop we found its just as easy to remove tank sorry thing there is no easy way
Forgot to mention, you'll probably need to loosen the fill pipe as well. And as previously mentioned, use hand tools to break the bolts loose as you may break the bolt or the torx bit if you hit them with an impact first.

Yeah I used to work in a shop and thats definately easier with a hoist and some tall jacks for sure. Workin in a backyard garage is a different story all together. In that case its easier to have four guys lift the bed and work on top rather than jack the truck up a little bit and crawl around on the ground under it. IMO if your working without a hoist, lift the bed fo sho.
Your rite tho.... either way really isnt the easy way, they both kinda suck in their own respect

you dont have to pull the box to get to the tank. drop the tank, worse thing that will happen is you might need to buy new tank straps, or repair them by welding a new bolt/stud to the strap. been there done that. and for my 2 cents dont buy an aftermarket fuelpump/sending unit, or you will be doing this again soon. ski

Listen to the man, I refuse to sell A/M fuel pumps at our dealership for this very reason. We've done it in the past and ended up eating the cost to replace them with OEM units.
