cracked my tank :(

[pathfinder]

Not sure when it happened but today when I was firing up the beast we noticed the tank was dripping... I took the tank off and it's cracked almost in half along the inside edge..

Can I just silicone it or would the fuel break down the silicone?

Anyhow, I'll probably just buy a new tank next time I place an order somehwere... Which looks pretty soon since the steering servo seems to have stripped aswell..

I would think it would be OK to use silicon of patch a crack on the tank, just let it cure good before you fill the tank with fuel

I used epoxy to attempt a repair on my cracked tank....didn't work to tell. I let it completely cure, and even sanded the tank for better adhesion. The fuel actually turned the epoxy yellow. I doubt using a silicone caulk would work perfect. It might seal it for a quick, temp fix, but not for long.

True, I forgot to mention that in my last post, good for a temp fix until you can get a new tank..........but there have been reports of people patching a hole in the tank with a piece of plastic and epoxy and it last for a good amount of time

Welcome to the "busted Savage tank" club. The only thing that I've found that will patch a cracked tank for very long is JB Weld. I patched one tank that had a hole punched in it with some hair line cracks (shock bolt damage) with JB and some fiber glass tape (the kind rc pilots use to join wing halves). It held up for almost a galon before it started to debond.

The other thing to do to prep the tank before you put the glue on it to wash it with nitro cleaner and then soap and water and rinse till it's perfectly free of oil. If there is any residual oil on the surface, the glue won't stick. Roughing the surface is good, but clean the surface before you rough it up.

Best solution is to get a new tank. Keep the patched tank as a last ditch spare. I've had to use these spares in the past when I completely busted the "new" tank.

Hey there error how's it goin? Good tip on tank patching, I'll have to remember that for my own future misshaps LOL

I haven't gotten the chance to get one of the primerless tanks, but the original kind of sucked all the way round. It's pretty brittle to begin with (only gets worse when it gets colder), and the primer will leak after a while, and not to mention the half tank leanout. It's a pain in the rear to say the least. I bet I've busted 5 to 6 tanks since I started bashing the savage.
