Old Blue EZ Gas Cap

[Deleted]

My Old blue EZ has a partially broken gas cap & I don't know if I can get a replacement cap because the style is different.I also don't know if this current cap will leak or not.I put a wire into the metal tube & pulled out what is like tar.Here is a pic:

That tar is what's left of the duckbill valve. You would need to pull the aluminum tube out, clean out the goo and put a new valve in.

Homelite PN 69451. Still in production. If you are fixing up a pile of old Homelites, you will need a bunch.

If the gasket surface of the cap is intact, it won't leak once you put the new valve in.

I have the same problem with the oil cap too.Does that take the same duck bill?

Yes. That's the only one they used on their saws as far as I know.

They let air into the tank but not out. Important to stop the cap from leaking, to let air in so a vacuum doesn't occur and to keep pressure high in the fuel tank to raise the boiling point of the fuel.

They should've used them on the Jonsered 361's.I remember when I used to refuel the saw the gas would boil.I didn't think it was very safe.

I think almost all saws had a check valve somewhere for the fuel tanks.

There must've been one on it,otherwise if you used gas out without putting air in it would've created a vacuum.
