Oem gas tank sealer woes

I have a problem with what ever Harley used to line the tank of my 2000 Sportster 1200 Custom. It seems the ethanol (or what ever other garbage is in most local fuel supplies) has broken down the gray colored coating inside the gas tank. It is no longer bonded to the tank, and is flaking off . It has already caused carb problems once, and it is doing it again. I know I need to install an inline fuel filter, but I feel this is "too little, too late". Has anyone else experienced this, and does anyone have any suggestions on how to rectify the problem? Thanks in advance!

Been there, done that & inline filters on Sportsters often cause problems because of where you have to put one they cut fuel flow down too much.

The solution is take the tank to a radiator shop, as they have the chemicals & equipment to clean it out to the bare metal & coat the inside again. The shop here uses a fiberglass product which they guarantee will NEVER come loose, chip or flake off & they charge $85 to do the job.

There are products like "Kreem" you can buy to re-coat the inside of the tank yourself, but I've never seen anyone have success with those & the reason is they can't get every nook & cranny inside the tank 100% clean. Kreem may last 6 months, a year, maybe longer, but then it starts coming off too & just because the metal wasn't 100% clean to start with. So that's why I say radiator shop - they do that type of work every day.

I agree with Art...had the same thing with my Heritage...at the time the Kreem kit was $60.00 here in Canada + I had to do the work, Radiator shop here wanted $90.00 to do the job and have experience with doing bike tanks, so it was a no brainer, I've seen a couple of Kreem jobs and they didn't work out very well for the reasons Art mentioned. It's been about a decade since the Heritage tanks were done and not a problem, no peeling or flaking.Find a rad shop with experience doing painted tanks.

Thank you, gentlemen. Good point about the fuel filter ... that never ocurred to me. I guess I will be looking for a radiator shop.
