Hi has any one got any recommendations on treating the inside of mildly rusty fuel tank I've seen a vid where a dude treated his with kbs fuel tank liner presumably after follow mfg recommendations and it all came away in big pieces of skin helleva mess i und fortunately bought the same brand b4 seeing the. Vid so I'm pissed then I saw a vid of a guy using POR 15 metalready after he'd cleaned his xj 650 tank out as best he could although I think I'd use white vinegar first and baking soda he left the metal ready surface in place stating it forms a sort of coating that is fine and helps to retard further rust formation any thoughts I may have to ditch the kbs I think looks to dodgy tia

Deox-C. Can be bought on line for around £17.50. I use Ebay for mine. Just bought a second bottle for my EXUP but yet to use it. First bottle was used on my FZ tank. It's a bottle but contains white granules not liquid. As I recall I mixed half of the content with water (can't remember if it was warm or cold but it will say on the bottle) & poured it in after blocking the fuel gauge sender hole & fuel tap hole. Swish it around a bit initially then just give it a swish every 10-20 minutes or so for an hour or two. I should imagine if I had used it all in one go there would have been less swishing involved but It works a treat whichever way you do it. Pour it out after a few hours. I Was tempted to just leave it bare metal but a mate gave me some POR 15 sealant which is basically a tin of silver paint that I poured in after making sure it was bone dry inside. Getting it dry takes a lot longer than you might think. I used wife's old hair dryer which is now mine! It actually created two tiny pin holes at the bottom when all the rust was removed but I plugged them with some chemical metal. Read loads of stories about using white vinegar, nuts & bolts, Cola etc but for what it costs I would recommend this stuff to anyone. No messing around, works without question, results are plain to see.

Hi Graham thanx for that r u just recommending th deox -c and or the por 15 sealant I'm a bit dubious about liners after a lot have renounced them and the vid I saw with kbs failing Iv got por 15 in my Honda gb 500 tank and I think some had come loose there seems to be so many ideas and brands on the market do u know if the deox- c leaves a etched phosphate type surface that ok to b used by its self tia

Sorry I've just realised it wasn't POR liner I used on my FZ but "Frost". I used a liner in my old Fireblade tank as it used to leak but it came away, twice! I think it was the POR stuff but it was over ten years ago so bit hazy with details. This Frost stuff has been in my FZ tank all year with no signs of flaking to date. The POR stuff came off within a month or just over. really bad. The Deox-C just leaves a bare metal finish. I was tempted to use it without the Frost stuff but it was free so I stuck it in.

Thanx Graham just watched a vid by andis motorcycle obsessions he recommends an Aussie product he's had gd success with called red white and blue I'd use the frost if we can get it in NZ I'll do some checking yes think my GB 500 tank is dropping its Por 15 liner not gd but that oxy stuff sounds gd Andi used electrolysis on an old GS 1000 tank and got rid of a lot of rust I've got an expensive paint job on my tank so am dubious about that method thank for the advice

I've done a few tanks of late (e.g. XJ550, GT250 x 2) I tried electrolysis (messy) but now I just use phosphoric acid 10-15% conc is all that is needed - beats all the old wives recipes.. once it's done it's thing rinse out with water and then alchohol (meths in UK) to 'suck up' the leftover water. If you wantto traet it further then you can but I don't bother. Fill with fuel and go.
If its crusty you can try the nuts and bolts and screws trick first of course.

On mine, I brought white vinegar, filled it up and taped the the top. Then just let it sit for 5-7 days. I then poured it all into a large bucket.. the viniger removed the rust and cleaned the tank..
Give it a go, as long as there is no holes...

Did 2 tanks with kby. Only used one tank so far and within months the liner started to peel from the tank walls. Alot of messing around and some $ for poor results. Just ended up paying a shop to cut my tank, clean well, tap out dents, reweld and reseal with industrial liner. $350 american.. Shame isnt it..
