If you had used the Search feature here on TGO, you'd find threads all about cutting the access door like:

Which means that whole the hole cutting is the same....4th gens do not have to deal with cutting their lines because there are disconnects at the top of the tank.
So your link is basically not a complete write up for the OPs car which is a 3rd gen. I already posted TGO links above that actually address his issue, so what was the point in you posting your only partially addressing the mod link?

Re: fuel pump.... where to cut
Sorry but that is a bad link, as in.....It is for a 4th gen so it doesn't fully address the OPs 3rd gen.

Re: fuel pump.... where to cut
The op was questioning cutting a hole, the point is the same, you cut a hole to access the fuel pump and seal it. your post's revealed cutting a hole and sealing it. The one i showed using a grinder, some use a tin snip, maybe getting idea's is not such a bad thing after all.
Your link implies that he can simply cut the floor & disconnect the lines. Boy he woulda been frustrated when he got in there & found out the truth.
Please provide full truths when giving people advice, not just part of it. Or are you the kind of guy that would tell a guy to remove the 5 lug nuts to get a wheel off, but leave out the part about having to jack the car up?

Re: fuel pump.... where to cut
You obviously did not read my links, because they DO address having to cut the fuel lines & reattaching them with more than just hose & clamps.

Re: fuel pump.... where to cut
Seems to me it would be a lot easier and quicker to drop the tank than to cut a hole in the floor of the car, cut the fuel lines, dig up compression fittings and extra lengths of hard lines, make a hole cover, paint, etc.
No I didn't read the links but I am familiar with the hole cutting process and yes, I have dropped the tank a few times.

It is faster, 45 minutes I can have the pump in my hand, people cant seem to grasp that not only is it something you shouldnt be changing often, at all, but that it also can weaken the car, all for how much actual time saved ?

Re: fuel pump.... where to cut
It is much simpler to do it right than to do all that is involved in cutting a hole. It's just very intimidating to someone who has never done it. Cutting a hole to get to something just an inch away on the other side appears so much easier. It's not!

Re: fuel pump.... where to cut
It doesn't take that much longer to drop the rear differential, Drop your exhaust and drop the tank.. I recently did mine in 5 hours out and in.. Of couse, I have done alot of work to my car and all the bolts are in perfect shape.. I would recommend the same thing, to do it right way instead of cutting holes in the body.

Re: fuel pump.... where to cut
Wasn't intentionally trying to start a cat fight but I got it out switched and sealed back up.... took about an hour.... I dont have a $500,000 garage so that was much quicker than trying to drop everything.

Weird that in a driveway with a few basic tools it can be out in 45 minutes.
