Oil Line to Tank Connections

Just documenting the location of the oil lines on the 1990 Sportster for replacement. The oil lines are in pretty bad shape (cracked and leaking at fittings) and all of them need to be replaced. Also going to replace the oil tank (the chrome one is UGLY).

Main Oil Feed Line (GREEN) 3/8″ ID oil line which runs from bottom outlet on the oil tank to the feed on the oil pump.
Oil Return Line (BLUE) 3/8″ ID oil line which runs to the connection on the back of the oil tank.

Vent Line (RED) 1/4″ ID oil line which runs from the case to the connection on the top of the oil tank.

The image below is the back of the oil tank and shows where the oil lines connect to the tank.

That big line coming off the tank is the oil drain line which will also be replaced.

The lines to and from the oil pump to the filter will also be replaced.

Not ready to replace them yet, will probably be a couple weeks before I get into that. Since everything is tore apart it was easy to get my eyes (and camera) on them to document the locations to make it easier to get them all back together.
