I don't know of any upgrades to the pump. I will defer to others with knowledge of modifications. However a saw of that age could have a pump diaphragm that is not as pliable as it was when new. Maybe just rebuilding the oil pump with stock parts would help.I've got an 036 that uses half a tank of oil to 1 tank of fuel. Can the pump be upgraded?
No diaphragm on these pumps. Mods can be done to increase the piston stroke though.I don't know of any upgrades to the pump. I will defer to others with knowledge of modifications.

I'm running a stock 036 with a 25" bar and full comp RS33.I’ve just modded the ramp and control bolt. Havent tried the 046 parts in an 036 pump. Never saw a reason.
If its a stock 036, a half tank of oil to a tank of gas is pretty good. A ported one can pull a 28 all day, so thats where its needed.
I have parts for both here. I can always look ans measure.
