Motorcycle and Scooter appreciation

those tank lining kits seem to have those that swear by them and those that think they are shit. I lined a tank with one i got from a company called caswell, I think, as it was resistant to the ever increasing mix of ethanol in modern fuels. I think it would have been fin bt never got to check as a mate smashed a hole in it with a screw driver while 'helping me out'. I spoke to a couple of restorers who said it was better to just give it a good clean and use an inline filter.

You won't find a conclusive answer online. I never bothered lining the replacement tank.

B.

it depends, if the tank is rally rusty inside it might pay to seal it, but it isn't a long term solution as it will rust through to the outside, even if the crap isn't getting into the carbs.
Best is to give the tank a few swills out with petrol, which you pour out through a rag into a jar and use again and again until next to nothing comes out. Then use a cheap paper inline filter but change it because they soon block, and gravity fed carbs soon run lean if the paper element is partially blocked. Whilst all this is going on look for a new tank!

Having used the POR kit, the two washes of an alkali solution and a rust stabiliser the the lining kit. After that the tank cannot be reheated as the liner goes to fuck.

What i have heard works is to clean the inside of the tank with bolts and washers on a wire ring and put that in to the tank to clean the inside by shaking it up then removing the wire bolts and then either petseal the tank or lots of cheap filters..
