Husky 372 Caps???

[rahtreelimbs]

I have a Husky 372 that I bought late last summer. I have very little time on the saw. I noticed that the fuel cap was leaking ever so slightly. Is this common on the 372?

I can't immagine that would be "common" or disregarded by Husky since a safety hazard. I would guess the o-ring isn't seated or got damaged.

Rich, mine doesn't leak a drop. Take the O ring out and clean under it. Check especially that it doesnt have a partial twist. The mold line on a lot of o rings will sometimes cause a small leak if it spirals across the seal surfaces.

...does it screw on nice and easy? ...plastic threads on the cap or tank slightly out of round or ding in them?

my old 372 (R.I.P) never had any leaks and my 365 is tight too. Check for any scratches where the oring seals against the body. The scratch would have to be pretty good size on the body for it to leak.

Yep.......the saw is new.

Yes, its very common. the oil cap is the worst. You must make sure the o ring is on perfectly and stays clean......Wish it had the stihl caps.

My caps don't leak but I had a leaky tank vent. My dealer said they had a bunch come thu that were loose, cock-eyed or just plain missing.

Are you sure it's the cap?

As far as I can tell.


I looked at the cap and the o-ring looked OK. I will try the cap off of another husky saw.

Mine has no leaks whatsoever... I had an oldersaw that leaked, but a new o-ring solved the problem...

Thanx Frank, that may just be the ticket!!!

OK, I filled the saw up with fuel. I let the saw sit on my workbench for 3 hrs. or so. The fuel cap leaked the equivalent of about 1/2 of a drop. I think I had saw dust in the area where the o-ring is.

Marky, I realised afterward that I could be considered touching on a sensitive area. Netree, I will be more careful.

When the weather is cold leaks seem to be more of a problem; guess the ribber is not as pliant and doesnt take much crud to hold off the o ring a bit.

Thats what i have found. Also the seem to leak of you over tighten them.

Take some calipers and see if the tank is warped where the cap goes.
