recently brought home 9n6637. very complete except it had no oil filter canister, pipe plug in the block under where the canister line should be connected and one line running to the oil pressure gauge from the back of the block. governor is cast iron with no provisions for a line as it should be. I bought all new oil lines and junctions & a used canister. the canister bolted up fine but none of the lines fit. the short line from the bottom of the canister to the block is 1/2 inch to long and the line from the side of the canister to the rear junction is about 1 inch to short.
Is there a difference between 9n-8n canisters, or did I get a mislabeled TO canister?
