Pin holes in my gas tank

Okay so I'm almost finished restoring this beauty and I've sanded down the tank and found two pin sized holes. The tank has been empty and open (no petcock or cap) for about a month. It's dry and hardly smells of gas but I want to know if it would still be a stupid idea to try and silver solder these holes closed. If solder won't work, can I fill them with any sort of putty? Thanks.

 

do you have a welder available for use? that is what i would do just to be safe... you could probably use JB weld but i don't know how well it holds up to gas... it seems to be super good against anything so i'm pretty sure it'd work.

 

if you want to be sure that there will never be any more holes or rust, you might consider using a tank liner like por-15. it will permanently seal up all the pinholes. I did my 550's tank about a year ago, and it's still holding strong. I'm finishing up the liner on the 750's "new" tank as I'm typing this. it's pretty labor-intensive, but worth it, IMHO.

j-b weld seems to work ok... I've used it to patch-up some pinholes on a Honda ATV. Not a leak since then.

 

here's one more option:

They make a commerical gas tank sealer available in the auto parts stores. JBweld will also work. I am currently using both. I am not worried about how it looks since the tank sits under a tank cover on the seca turbo's. So far it's held up for about a month and a couple of 600 mile long rides. Just make sure that if you do use one of the putties that you keep a bit stashed away just in case you develop another leak. If you can afford it do a search for motorcycle fuel tank repair. I think there is someone that will fix the tank but it's expensive.. About $350.00 if I remember.

awesome thanks for the suggestions, I'm probably going to go with some good ol' JB weld.

 

if you have a soldering gun

you can solder a 1/4 inch hole shut pretty easy, a little more permanent than jb weld
