Installed a new lift pump on our Yanmar SB12 engine.
I learned this past week that our engine was a Yanmar SB12 and not a Yanmar YSB12. 2 different engines. I had seen references to both SB12 and YSB12, but thought they were one in the same. The SB series has a horizontal crankshaft & vertical cylinder (the YSB has the opposite). When I was trying to find a source for the fuel lift pump I asked for a pump for the YSB12 and found out that the YSB12 used an electrical pump and not a mechanical one like ours.
