Dolmar 120 Fuel/ leaking issues
« on: November 29, 2015, 01:21:02 pm »
Might as well pick brains..

Need a source of parts to freshen up the fuel line and vent parts on an old 120 series Dolmar.. Put it on its side and it leaks. Haven't pulled it apart yet and HOPING standard fuel lines can help or solve its issue.. but suspect its never that simple.

I believe the top center of the fuel tank has a plastic piece with an o-ring where the tank vent and fuel line is connected.   That piece can sometimes leak.  You will have to pull the handle loose from the saw to get to it.

I had the same issue on a 116 SI and it was the plastic fitting that
presses into the fuel tank. There is no "0" there but the fitting is
knurled on the side to make it a press fit and seal. I had to replace
the fitting.

Did not remember that it had no O-ring.    I have seen them on eBay for sale.   Just type in the part number and it will pop up.
