Help..Leaking Fuel Tank.

[Motu]

Use a hair dryer or heat gun to dry the tank before you put in the liner....take the tank with you if you go to the movies and keep rotating it every couple of minutes.

My VF500 had a rust pinhole on the right rear, where any moisture in the tank tends to end up and not get out again. I soldered up the hole, and treated the tank with the "Kreem" stuff (apparently not as good as POR15). This comprises a rust neutraliser (basically orthophosphoric acid), a cleaner/drier (basically acetone), and the liner (a thickish plastic that uses acetone as a solvent).

It didn't work that great, despite me following the destructions implicitly (and to the letter as well). Two problems: the liner is difficult to get into all nooks and crannies, as it is not very runny, and the soldered bit of the tank promoted more catalytic rusting of the tank, as steel is more reactive than lead. So the pinhole leaked again. And again. It wouldn't have mattered if the liner had covered the pinhole thickly enough, but it didn't.

Oh yeah - and the tank capacity was reduced by slightly less than the volume of the bottle of liner.

Whatever you do, do it right, so you have to do it only once.

The Por15 system uses the same type of rust treatment/etchant,after cleaning with the caustic cleaner,but the sealant is an isocyanate polyurethane.This is cured by contact with moisture.

So the Gloves bit was important????Cause I think theres not many crimes I commit tonight would link me to the finger prints I had this mornning!

Sry just re read the bit about moisture...As I understand it if it not as dry as a Nuns.... Prayer Book, it dont work! and the instrutions are clear about that.

Quote:

"Your tank has now been completely cleaned and prepped ready for sealing.

The tank must now be bone dry - DO NOT SKIP THIS, otherwise your sealer will not work properly e.g. Leaving tank in the sun for a few hours is not bone dry. Best method is to introduce moving air into the tank with a vacuum cleaner, fan, dryer etc and/or warm tank to evaporate moisture from inside."

All fixed and back on the bike (couldn’t wait the last 4 hours for it to cure 92 hrs has to be enough) No leaks so far.

The ride tomorrow will tell.

Thanks again for the help and advice.
