Fuel Tank Puncture
Anyone have success using JB Weld on their Fuel Tank for a small puncture? The hole is only about an 1/8 of an inch, really a pin *****, emitting a seep on the bottom. Driving through the field picking up bails of hay and the rear tire lifted a downed post and slapped the tank.

With this truck being solid and will not be parting with for some time I will get the mesh kit, Never heard of using Soap before. Learn something new today, already siphoned the gas out as too not loose close to 5 gallons. Thank you for your quick replies.

Make sure you get all the gas out and the area is REAL dry, also be sure to prep the area you are applying the repair too.
As in rough up the area around the hole so the repair has something to stick to better than smooth metal. And let the patch or JB weld have plenty of time to set up.
Ever head of potatoing a radiator leak?

Oatmeal and/or raw eggs will also stop a radiator from leaking. When the radiator cap is removed, the stench of the raw eggs is simply awful.
Diced up banana peels will stop a rear axle from howling...for a short time.

Cleaned the tank after jacking the rear end to get the remaining fuel away from the small puncture. Sanded it with 80 grit paper and cleaned with with an alcohol wipe so residue is left behind. Applied JB Weld by pushing it into the indented area and fared it around for about a 2" area. Going to let it stay up for the weekend before de-jacking and topping of. I have pictures and will get them posted later.
I cut a piece of the tread off my tire to get me down the road to the auto store when the spring inside the rotor button broke, ran like crap but worked.

Get a bar of Ivory soap and rub it over the hole till it fills it in. The chemical reaction of the soap and gas cause it to harden. I ran an E-150 with a small gash in the tank for years after doing this quick "temp" fix. I also Never go anywhere without this in my tool kit. Pops

I used ivory soap on some pinhole leaks. Works great. Has held for 5+years for me

Another option is 2 part epoxy putty in a stick (HW store and AP store). You cut off what you need, knead to mix then use it. Sets up fast. Some brands claim OK to use when wet with gas... though cleaning first is better.

In the case of 1973-79s, the cost of a new tank is relatively low (as little as $120 if you do some shopping around) so if it were me, I would go that route. I did a temp fix like that on a 1957 Cadillac back in the 1980s but eventually I had to go salvage yard hunting and get a different tank. Gasoline fumes and leaks are nothing to mess with.
