Default Re: 79 G1 exhaust, small tube from oil pump

What you are seeing is normal. There is no oil that runs through that tube. The part thats screws into the muffler is called the jet sensor. It detects pressure from the exhaust and helps the oil pump function. The oil is pumped from the oil injector into the side of the carb.
