Hey guys. I picked up a low mileage 93 not to long ago. The only real issue I have is it came out of a boneyard so the tank has been punched. Any ideas on plugging the holes so I can use it? I have dropped a bunch of cash into it to get it where it is so I can't afford to replace the tank right now.
My boss has an idea to use a carriage bolt and a plastic washer to seal it with some rtv on the outside. Thoughts??
This would of course be a temporary deal, not permanently installed. I WILL be replacing the tank when finances allow for it.
Thanks guys. Any input would be appreciated.

What in gods name. No. Fuck no. Wait and buy a new fucking tank. Or steal one from a boneyard. Its held together by RTV and a fucking bolt? I thought I was insane for driving a Datsun with no floor pans like I was Fred Fucking Flintstone or something. Dear god man.

Tank is plastic. There are many ways of doing it. Drill the hole out and use a small boat plug of sort. They also have plugs that tighten up (expand) as you tighten for oil drain plugs that are stripped. Changing the fuel tank can be a good amount of work. Tons of ways to do it.Originally Posted by datto62073

Its not fricken titanium welding man. Its plastic.. Drop the tank. Clean the piss put of it. Plastic weld the bitch shut. Melt a glob over it and melt it together some more until it looks like butterd pancakes. Fixed. ..

Wait the gas tank in our car is plastic?

It's not in the car, it's under the car.

Pull out the senders for good access. Nut and bolt with two big washers and some thick rubbery stuff that's petrol proof should work. The kind of temporary repair that lasts forever. I'd probably put some RTV between every layer inside and out. Burrs on edges need removing.

Tank is indeed plastic. When you remove it a lot of times the tiny little nipples for the vent lines break. I had to repair mine with brass fittings and JB Weld. New tanks are expensive. Auto stores sell a patch kit which has fuel resistant epoxy and a heavy duty canvas patch plus sandpaper. Rough the area, cover the canvas with epoxy, set it, and use even more epoxy

Ok cool. Thanks guys. That's exactly what I was looking for. I'll look into the patch kits and other options.
But as said, this will be a temp deal till I find a good solid tank to put in. I just need it to last long enough to make sure it runs. Once that's been taken care of I will be swapping the tank, flex disk, and putting in new exhaust.
Hopefully it'll pass inspection without exhaust as I don't have any. Jan 2nd it goes in so hopefully I can get it at least transferred.

Had my tank dropped to reinforce the rear trailing arm pockets, & the evap line nipple broke off, so the fabricator plastic welded it together. Well, that failed 6 months later, and I decided to replace the entire tank with one from a local part out. That was last month, but its nice peace of mind.

If all goes well I found another tank from a part out locally. So hopefully I can get that one. If not ill plug this one and keep searching.

I wouldn't want to take a chance on something critical like a fuel tank personally.
