Has anyone used fuel tank sealers for their motorcycle?

Question

I have seen adds for
POR15 U.S. STANDARD FUEL TANK SEALER
and Kreem FUEL TANK LINER KIT.

Has anyone used these products or any other similar tank liners, and what is your comments on how well they work.

Answer 1

Yep - Kreem works great for fixing old rusty fuel tanks.

Answer 2

It's a good idea at any time but especially if you're getting ready to put that dream paint job on. Last thing you need with a custom paint job is to find a fuel leak.
Make sure you follow the instructions with the product. Clean the inside of the tank thoroughly. Many new tank manufacturers coat the inside of the tank with something to inhibit rust. It all needs to be cleaned out to ensure a good even coat of the liner and that it sticks to the entire surface.
Think about putting something like a pipe cleaner in any ports that will need to be clear. Like on Harley split tanks the top vent ports and crossover fuel ports. You can move the pipe cleaners up and down during the drying process until you're pretty sure it's started to set then pull them out. Trust me on some of the 90 degree ports it's a ***** to try and clear them after the liner hardens.

Answer 3

I got great results from using the Cycle Tank Kit by KBS Coatings. They have 5 & 12 gallon kits depending on your size tank. Kits includes a cleaner, prep & sealer. Follow the step-by-step directions. The KBS tank sealer is different than Kreem. Kreem basically sits on top of the metal and can peel away with repeated expansion, contraction & vibration of the tank.
The KBS sealer seeps into the pores of the metal & interlocks with it. It cures rock hard yet can flex with the tank.

Answer 4

A lot of people like the product Kreem, But the liner can peel off if the tank is not perfectly clean. Your best bet is to go to your local radiator shop and have them seal it. Ask first if they seal gas tanks though. If they can't seal it, they can boil the tank out for you.

Answer 5

Answer 6

Paint stripper is the easiest way. If possible, take the pieces you're stripping outdoors for this job. This provides better ventilation, and the heat of the sun helps speed the process of some strippers. For some strippers, it also helps to lay sheets of plastic wrap over the wet stripper This prevents rapid evaporation of the solvent, and helps speed up the chemical process. Tip: To make it easier to remove the paint or varnish once the chemical has had a chance to soften it, sprinkle sawdust on the wet stripper This makes removal of the finish easier, and it simplifies cleanup. Use a plastic putty-knife for scraping away the stripper and paint or varnish. Try to select one that won't mar the surface and use caution as you scrape. Finally, be patient. Stripping finishes can be tedious and time-consuming, particularly for intricate pieces and detail work. Being patient and methodical pays off. Recap: Choose the correct type of stripper for the project. Wear safety glasses and gloves. Be patient as for the undercoat just be sure to use the right undercoat/primer that is meant for the paint you are going to use.

Answer 7

yes my 1953 Ariel has some Brazed repairs and I used tank seal in 1972 repainted the tank and never had a leak

Answer 8

I used the POR-15 in a '59 Chevy gas tank. It's permanent

Answer 9

I've used Kreem.
It works, but it makes a mess.
Use plenty of drop cloths or old shower curtains, to keep that stuff off your work bench.
Always install an in-line fuel filter after sealing a gas tank.
That stuff is eventually going to chip off and you don't want it in your carburetors.

Answer 10

My police bike had a hole in the gas tank from rust. I just used latex caulk. *shrug* Would have been very embarrassing if that hadn't worked.
