I mentioned in an early thread (https://rennlist.com/forums/924-931-...rom-hatch.html) that I have a gas smell in my newly acquired Porsche 944. I was looking into it today and found that a small hole had been drilled from the trunk into the gas tank. :/
Do you know why someone would drill a hole into the top of a gas tank? I asked the previous owner and he claims to know nothing about it.
Any recommendations on how to fix the hole? My current plan is to use an epoxy to seal the hole. Thanks!
That's not your gas tank, that is the floor of your hatch area. The carpet has clips that fasten into those holes (there are more.) Since you have a one of the metal gas tanks that are subject to stress cracking, I suggest you google 944 gas fumes and look through the results. Your tank may need to be dropped and have reinforcements added if it is cracked.

the hole goes through the floor and into the gas tank. I put a skewer in it and can see it when viewing the gas tank from the fuel level sender opening.
The hole should be easy enough to repair, perhaps install a screw with gas resistant sealant. Unfortunately, the tank will likely need to be removed to make a sure repair. Research the common stress crack areas of these early tanks so they can be inspected / addressed while it is removed.
It looks like whomever drilled that hole was using a hole.saw for something and that was the centering bit because they also caught the hole saw circumference from the curve that I see around the hole. Likely they thought better of what they were doing after the centering bit already went though.
One solution might be to carefully make the hole in the metal just a little bigger so you can get some JB Weld through it and into the tank to repair and seal the hole. It will work great for that and hold.
Try and see if you can get some epoxy over it by going between the trunk floor and tank via the sender unit hole. Maybe a long stick with some epoxy dab on it? Otherwise youll need to drop the tank (and while you are at it, inspect all the breather lines running to/from the tank for holes as well as your fuel filler neck)
