Unless your truck is STRICTLY a shelf queen, never to be run, then never buy an aluminum tank. They are heavy, you can't see your fuel level, and they're completely unnecessary.
You can install a level tube on them. There shiny nice lookin but bottom line they suck .Metal tanks were pretty much comon when i raced 1/8 scale cars many years ago they were fine if you had x-ray vision.LOL
Granted the alum tank doesn't offer any advantages (and aside from visibility, no real disadvantages either) I don't see what the fuss about being able to see fuel level is anyways. Even if I had a clear tank I can't see it with the body on anyways.
Wear a watch and bring the rig in every 6 or 7 minutes. Done.
In all honesty I don't see an issue with an Integy fuel tank either. Bulkheads, suspension components, shock towers... yeah those are no-no's, but a fuel tank is a relatively unstressed piece.
I agree with Lessen there. I see an alloy tank as a bit un-necessary but hey what ever floats you boat right? I don't see them as a "bad" thing just more of a...Why? Integy "MIGHT" be able to get that one right.....maybe.
I ran one on my t-maxx because I was busting tanks right and left. Broke 7 of them, then got a hurricane alloy tank, I think that was the brand.
I had a difficult time keeping the screws holding it to the chassis tight. Didn't seem to matter how much locktight I used, they still came loose every run. After a while of using it, the threads on the screw cap started to wear which caused filings to go down into the tank.
I ended up reorganizing the chassis and putting an OFNA 1/8 buggy tank on it, then had no more issues.
