My 2001 GS has about 16 inches of air at the top of the oil feed line which comes off the top of the oil tank. There's a T where it attaches to the oil tank and a plastic thingy that looks like an oil filer (cone shaped) or a one way air valve with about a 1/4" barb on the end (for attaching a hoze). How can I get the air out of the line? I worried that it may work itself down and cavitate the oil pump.
