fuel tank internal rust

[mirror man]

hi guys my tank is in fairly good condition with some light rust in side, i dont think it's ever been sealed, im looking for some advice, should i leave it, clean with bio rust type cleaner , clean with soda crystals plus a 12 volt charge ???? any suggestions thanks alan
see some pics

12 volt charge would be a good idea if you were dealing with a new tank . but as the the rust is in it now . i would look at getting pet seal . the loose and easy moved rust try a handfull of dry grit and shake it around in the and empty .

Use Bio-rust. Leave it in for a couple of days until all rust has gone, wash it out with clean water ensuring all loose material has gone then purge any remaining water droplets with wd40 or white spirit and refeill with some fresh fuel. Job done!

I got mine from ..Caswell 01420474961 at £18 a litre inc delivery, into the tank and mixed with hot water to the brim worked a treat. they call it comscale 650

As Coldsummer says, also sealants can peel and cause even more problems, i always keep my tanks full of petrol even when the bikes have less use in the winter, looking at yours it appears its not serious just a basic cleanout should do it, i have always used D.I water to rinse after cleaning no chemistry in it.

I have used half a gallon of diesel with a handful of nuts and bolts (counted them in to make sure none got left in when finished) and just swill it around for half an hour or so. Once finsihed turn out the diesel and swill the tank with some fresh petrol or white spirit and that should be sufficient. Worked for me last year.

My tank looked about the same as that. The problem I had was that the rust had gone deep into the seams on the underside of the tank which caused pin holes through this seam.
I only found this out when the tank had been blasted and sprayed
Luckily I had a good mate with a welder and brazing rods who sorted it for me.
I then sealed it with POR 15, a three stage process and looks to be good so far. I bought it from www.frost.co.uk

Alan, I've used Bio-Rust & had some excellent results with it, don't fit a liner unless you really need to, and looking at those pics I would say that you don't.

I've used plain old malt vinegar before, left it in for 5 days, poured it out then put the nuts in to loosen the crud then rinsed with water then as much WD40 as you can. It's cheap but very effective and works ok

thanks for the advice guys, im gona go with bio rust treatment, im hoping not to have to use a sealer/liner, there seems to be lots of horror stories about liner failure/gunge in carbs etc... thought to be due to the increased amout of ethanol in unleaded which i believe is due to be increased further again next year, i think i might fill and check the tank for leaks tomorrow as its been bone dry since i recently purchased it [fingers crossed] ps need to keep the malt vinegar for fridays fish & chips special

where can you get bio rust?
do you need to protect the inside after pouring it in?


any tips on this method?
