PVC works for me......

My Kit tank started leaking from one of the studs. I tried Seal All, and it sealed nothing, so I made what you see here. It's weird, but it works.

Love the original pvc tank very inventive. Don't throw away your leaky tank, regular silicone from any hardware store will seal it up permanently. Had that problem on a motorcycle tank, the stuff is still holding since 1970. I still ride the bike to this day a 1969 Triumph.

I'll give the silicone a try. I have Permatex RTV Blue, do you think that will work?
 
I'd go the Ultra Grey, after a good cleaning with MEK or acetone. Is that a galvanized pipe cap for your gas cap?
 
Personally, I would stay away from silicone, JB Weld, and just about anything besides solder or brazing to stop a leak....the additives in modern gas will eventually eat through just about everything, except vinyl ester resin.

The cap is brass. I used a 3/4" close nipple (brass) tapped into the PVC elbow. The cap is vented and I made a plastic baffle to prevent leakage. The PVC is 2" SDR21, same material as SCH40 but with a thinner wall.
 
I like that a lot. As stated it opens up a lot of possibilities. Time to hit the drawing board me thinks.
 
Now I have been taught that gasoline, especially ethanol, will eat away at PVC and PVC glue.

junked, please keep us informed as to how well this works out for you in the long run.
The possibilities are endless if it actually works out.
 
So Far so good with no leaks. I found this chart Berghof/America: Chemical Resistance Chart listing chemical resistance of various materials including PVC. I think the PVC Cement, as it is called is of bigger concern than the PVC itself. To join PVC you should first use the "cleaner", witch softens the PVC, and then apply the cement. Once joined you have about 3 seconds for adjustment before the joint is rock solid. As good as that is, I still don't know how well the PVC cement withstands constant exposure to Gasoline.
 
My understanding is that regular PVC cement and "cleaner" won't hold up to gasoline, I used "Seal All" to glue my tank together and it worked fine. There are a variety of adhesives that will work fine to glue the pvc together, go to your local auto parts store and you should be able to find something.
