Hi,

Hoping to get some help. I’ve searched for a few days but haven’t been able to find anything. I have an early oil tank, #956-137. I think that the o-ring has swelled and I’m having trouble getting the tank lid to seal. Does anyone have the size of the o-ring. I bought a new one but it is too small ( 145x6 ). I spoke with Rotech in Canada but they couldn’t find the number or size. Said their parts book only went back to 1995.

Any help will be greatly appreciated.

Thanks.
