FL120 oil hose fitting size

[meridian]

Any idea what size fittings are on the oil lines from the engine to the filter on the Lehman 120? I'm going to relocate the filter and just want to add pre-made hoses.

I don't know offhand, but I do know and have bought and installed the oversize hoses recommended by American Diesel. Apparently low oil flow to the number six bearing and rod assembly has been a problem in the past. The kit did not need new fittings so I didn't have to go shopping. The new hose is approx. double the I,D.
