Rust in tank - treatment?

[gjm]

One of the pitfalls of buying s/h, especially an older bike is that there are always going to be issues that onl arise after years and years.

I'm due to pick up an older bike very soon. One of the things I know I'll need to sort is the fuel tank - looking inside, it is predominantly very clean but there are a couple of areas inside the tanks where it has started to rust.

Draining it and drying it out obviously isn't an issue, but does anyone have any tips for treating the rust and generally sorting the tank before use?

I'll be checking the carbs and so on before use, of course.

I used the Por 15 kit myself and it worked ok,secret ts the prep though,in my case i started with one small hole which i fixed then sealed the tank only to find a bit later things were worse than i thought,blew the thing out with a water blaster which revealed holes everywhere.Fixed them and redid with the sealer.

I did do a search, and trawled through 5 or 6 pages of listings based on 'cleaning' and 'tank' in the 'Fuel and exhaust system' sub-forum. No luck... Hence the question.

Thanks chaps. I'll have a read and look into this. I don't think there are any holes (yet), but hopefully that'll mean the solution is simpler.

Ive recently bought an old 74 Motorsport project and though theres no leaks i will be using the Por kit on that due to its age.

Correct answers (YOU want) are only given to correct questions (YOU ask) ...

Have a good look through the "Fuel and Exhaust system" forum thread titles.

The simplest solution is a NEW tank ... :yes:

But I'm guessing ... you want a cheaper solution ... <_<

My project is a little newer - built in 1979 or 1980. There's no obvious leakage from the tank, but there's some very light rust freckling on the underside (easy to sort) and a couple or patches of rust inside. Doesn't appear to be scabby, so will hopefully be simpler to sort than if there was any permeability or holes.

There's going to be a fair bit of work involved before it's back on the road, but for me that's part of the fun. :)

Like 4 years make all the difference ...

Remove the rust and there may well be ...

Remove the rust ... you weaken the steel panels. "Permeability" is reduced.

Do it right the first time ... and install an inline fuel filter ... before any (more) rust gets into the carbs.

I used a POR15 kit for the tank on an old bike I had that was full of rust and gunk after sitting for 10 years, takes a while to go through the process but sorted it.
