bought it like this. didnt know it at the time until i stripped the interior. im sure it wont pass a track day tech as-is. the hole came in handy for the re-wiring i had to do. should i weld, or seam seal a patch in place......since there is already a hole there, is there something with a trap door in it for access, should i need to do the fuel pump or wiring again. i don't feel like welding on top of the tank. would a seam seal patch be good enough for track techs.

Piece of sheet metal, short self tappers and silicone.

Paint and done.

You could probably also just pop-rivet a panel in place. Seam sealer or silicone on the seam and over the rivets, and you should be good to go.

Either of the above will work. I wouldn't bother with paint.

I just riveted a piece of aluminum to cover it. Allows for easy access if needed. Passes NASA tech.

Use pop rivets to seal and attach at a patch - make the patch wider than the groove on each side so it will lay flat on the deck and use plenty of RTV in the grooves

USe a drill stop or a bunch of wraps of tape on the drill bit so you don't hit the tank, and don't drill above the plastic lines. I use .060" aluminum.

it had a square of sheet metal screwed over it, then duct taped down. indicative of how the rest of the car was. ill probably try rivets and silicone. that will pass a typical tech?

I'd be ok with it. This is a common modification with racers. As long as there's something of patch panel and a dent attempt at sealing it up ill pass it.i have something similar on my 4th gen.

do you leave it like that or do you seal it with something

Have done a couple of these already and I like running .060 aluminum with RTV sealing it off on top of screws. I actually used 10-24 rivet nuts with 10-24 screws, but I guess self tapping screws are sufficient.

I the the PO had it nailed....duct tape!

Eventually I plan to cut mine out and make a panel with a foam rubber gasket and rivet nuts around the perimeter. My 97 olds Aroura had that from the factory. Made life so easy when it needed to be serviced.

I used a couple strips of aluminum tape around the edges. Seals like a champ and easily removable.
