How to Assemble a Harley Oil Tank Hose
There are only four possible oil hoses on any Harley-Davidson. One hose, usually called the "feeder line," carries oil from the oil tank to the oil pump. Another hose, usually called the "return line," carries oil from the engine to the oil tank. Harleys built after 1992 have a third line, usually called a "vent line," that connects the oil tank and crankcase. All Harleys have a way to drain the oil from the tank (sometimes it is a "drain line" and at other times a "drain-feed" line). All connections are straightforward and are made with either hose clamps or hex nuts.
Instructions
- 1
Drain oil from the oil tank through a drain hose by loosening a hose clamp at one end of the hose with a flat-head screwdriver. Turning the screw causes the clamp to expand or contract. Pull the drain plug from the end of the hose when the clamp is loose.
2Loosen the hose clamps that connect oil hoses to possible T-fittings and elbow fittings by loosening the hose clamps there with a flat-head screwdriver. The hose clamp tightens the flexible hose to ridged metal connections on the fitting. When the clamp is loose pull the hose free.
3Loosen the hose clamp connection between the oil tank and the feeder line with a screwdriver. Tighten the connection between the feeder line and the fixed, threaded, oil pump fitting with an open-end wrench.
4Push the oil vent and oil return lines through the rubber grommets in the holes near the top front of the oil tank.
5Connect the crankcase end of the oil vent line to the fixed, threaded, crankcase fitting with an open-end wrench. Connect the oil pump end of the return line to the fixed, threaded, oil pump fitting with an open-end wrench.
