To the original poster:
Its your choice, pay an @ss load of cash for a simple fix, do it the "right way"
Or...
Take an afternoon, do it yourself, take the extra cash you saved from taking it to a mechanic and take your girlfriend to dinner and a night out. Hell maybe even save enough money to go on a weekend vacation.
Its up to you, but good luck with it. Let me know if you want a pump. I still have my stock one I'll sell ya for really cheap. PM me if your interested.

Well I cut a hole in my floor, but only after the tank was out of the car- dropping the rear-end, suspension etc.. But I cut the hole because the -10AN feed line and -8AN return line won't fit above the tank. They actually protrude an inch above the floor before going back down.
I didn't want to do it- but really didn't have a choice. As far as structural integrity, with the SFC's, various braces and cage going in, I think those will make up for it.

i dont wanna sound like an idiot and im not even gonna lie and say i know anything about this but if u cut the hole then weld it after wont it be basically as strong as it was before u did it if its welded right? i havent and wont cut a hole in my floor but im just curious, i know alot about other things on cars but welding isnt one of them

But yes, ideally if you weld it shut it would be fine (theoretically).
I worked in a body shop for several years and I cant fathom how cutting a small hole in that area will affect structural intetgrity.

Any hole in a body obviously compromises strength, but in an area above the fuel tank I don't think it would be as compromising as other areas.
The only perceivable way to weld it safely that I can see would be to make sure all your spilled gas is evaporated and then make sure the welding is done in a well ventilated area.
Take the piece you cut out and weld a 1" tab around the edge of the piece first, then weld that tab on top so that you're not butt welding above your tank. You will still get some sparks, but there will be considerably less that way. Its still a crapshoot though-
The safest way is obviously dropping the tank, but cutting a hole is another way, although i wouldn't recommend it- one slip is all it takes and you either end up with a cut line, gash in your fuel tank or other.
If you aren't comfortable with doing the work to drop the tank, I dont think you are the right person to grab a grinder and cut a hole in your floor.

IF thats even possible and you are hit that hard in an accident, then the last thing you will have to be worried about is leaking fuel cuz you'll already be dead.
