    Default 1997 sporty 883 oil line routing help

    Chopped a 1997 sportster 883 currently trying to run some oil lines and need some help. I have a service manual and have done some research but for the life of me cant figure it out. i have a tc bros pill oil tank with 3 bungs. 2 at the top and one at the bottom.
    There is one hose coming out the top near the tranny mount,vent?
    A Hose going straight into the oil pump, feed?
    A hose going into the top of the oil pump on a angle, return?
    A hose coming out of behind the cam cover with a 90 degree brass fitting pointing up, vent?

    I assume the feed would go in the bottom bung the 2 vent hoses could T together and go in one of the top bungs and the return can go in the other top bung?

    Any help is much appreciated

    Leave the trans/primary vent to open air.
    Tuck the hose wherever.

    Plumb the cam chest vent to the highest bung on the tank.

    Return line goes from the oil filter thru the bottom of the pump,
    then back to the next highest hole on the tank.

    Feed line gravity feeds from the bottom of the tank to top of the pump.
    If there are two lower bungs, use the lowest as the drain.
    And the slightly higher one for the feed.
    Kind of an in tank sludge trap that way.
    You say only one lower bung? Put a tee in the feed line as a drain line on the third leg...
    Route this hose with clean, on kickstand oil changes in mind.
    A threadless bolt makes a great in hose drain plug.

    Don't forget to prime the pump before starting her up.

    I do believe this is wrong. The big bung on the stock oil tank that comes out of the back goes to the lowest point on the pump and to the drain hose. The 90 degree brass elbow on the stock oil pump thatís highest up goes right into the tank and has an inner tube in the oil tank that goes to the top (return)
