Some 30 to 40 years ago, if i recall correctly, when asking around about how to remove dents from a fuel tank, the response was always, "you don't", followed with some sort of reasoning about it being impossible, dangerous, faulty, etc. etc. And i also remember somebody telling me that the only way it "might" be done is to blow the fuel tank up with compressed air, slowly, carefully, until the dents pop themselves out.

On the presumption that everything i used to know was forgotten for a reason that i can no longer remember since i forgot it . . .

Is it possible to repair dents in a fuel tank?

If not, what is the most popular solution to fuel tank replacement these days?

the answer is complicated.. there is a way in which to repair dents in the tank.. but with out actualy having the tank in ahnd, I would not be able to even begin to give you advice how... its not as simple as pulling a dent in a fender of a car.

I've seen it done where you fill the tank with water and freeze it water expands as the ice is formed and the dents are pushed out. However I've also seen a tank split at the seams when left too long or filled with too much water.

That sounds FAR better/safer/slower than compressed air. I might actually try that if i can figure out how to freeze a tank cheaper than replacing one. Seems to me the water could be tried with less than what one needs, see how that level works, add a little more, etc.

I am lucky these dings ( 5 of them ) are all pretty small and shallow. They are hard to see as well. They are in places that are nearly impossible to ding unless one was in a bar fight or parking under weak trees. All five are on TOP of the tank forward or aligned with the gas cap, ~two inches~ or so apart from each other staggering the tank like a crown. If they can be restored, the tank will be worth repainting.

I'm a lazy **** and just fill em with bondo

For the costs involved, that might be what i end up doing. But do you know any another tanks from other bikes that would fit our frames without any major mods to the mounts?

as long as the other bike is an 85-2006 vn750... your gold.

pretty much any other model bike is gonna need mod's to the mounts (as you suspect). as far as what fits better than others, I dunno

Someone did a vn800 tank

Good thread. I guess what i need more than a fuel tank is a garage with a lock on the door.
