Gasket maker

[HWRDBNZ]

Is there any gasket maker in a tube that is ethanol friendly? Need to reseal a homelite 150 auto gas tank.

None of the gasket makers I’ve tried will take direct contact with gas and ethanol. It had a gasket didn’t it? If it did best off making a new one

 

[HWRDBNZ]

If they did it was super thin.

Is it a screwed together tank? I don’t know about the 150’s but years ago some homelite saws had glued together tanks that failed. They recalled them and put screw together tanks in place.

Found this.

My suggestion would be to buy a thin sheet of gasket paper. Trace out your tank with a small ballpeen hammer onto the paper. Then use your sealant you found. I would be a little leary that sealant alone would be enough. Just a suggestion. Tim G.

Ive always had good luck with Permatex Moto Seal on crankcases, never tried it on a fuel tank though.

The motoseal won’t work I tried it on an 075 tank and it made one day

3m weather strip adhesive. Also known as monkey snot. Is what omc used to seal tanks from the 70's up to the early 2000's. It comes in classic yellow and now more discreet black.

Good luck ever getting it apart if you go that route.

Dont use ethanol fuel is my suggestion, but I've had no failures with Yamabond4.

Motoseal is supposed to be resistant to gasoline, and is made for exactly that purpose, sealing case halves.

Sealed the tank on homie C5 with motoseal. No gasket. No problems. Make sure you let the motoseal cure for a day or two before adding fuel

Are you using Motomix or other canned fuel?

I've found that the Permatex Right Stuff gasket maker is stronger than ThreeBond, Hondabond, Motoseal or Yamabond. It's the only thing that seems to hold up sealing the case halfs of my KTM 450 dirt bike.

This is a little expensive, but works well. If you go this route let me know, surface preparation is important, as is working time and cure time.

No, regular out-of-the-plastic jug premix

BTW, I did that C5 bout 10 yrs ago. Homelite publication said don’t use gasket. Don’t use it often but no leaks when I do

DAM how many times you sealed up them case halves?

Too many times. Threebond kept failing to seal around the oil filter and it would push oil into the cooling system.

Case sealants don’t hold up well in constant fuel submersion
