I have a soft tail horse shoe tank on my bike and I can tell which line is the return or vent. I've figured out that A is the feed and sticking a flashlight in there it looks like C has a tube running all the way up tank so Im guessing thats the vent which means B is the return line, I just couldnt see any corresponding tubes or openings. Im just double checking if anybody else has this oil tank and can confirm before I run my lines and blow up my motor.
