1990 Harley Davidson has not been running in 4 months, started it up noticed oil coming out of the vent tube, I hear its normal about 1/2cup. Is it a problem?


Hi, Robert it's called "WET SUMPING" most Harley's with external oil pumps if left sitting for weeks or months will eventually let the oil tank contents drain pass the oil pump check ball and fill up the bottom end of the crankcase when the bike is started the excess oil will gush out of the breather vent and if routed to the air cleaner will also flood the filter. This messy condition will continue until the bottom end is forcibly emptied by the flywheels or manually drained if there is a plug. There are 3 options you may want to consider:
1. Drain the oil tank before storing the bike.
2. Replace check ball and resurface seat in the oil pump.
3. Install inline ball valve shut off in the feed line to the pump.

1996 sportster oil tank has 3 hose fitting the 1984 got 4 fitting how do you hook up hose ? from 84 to 96


Hi, Onebob yesterday I sent you a free service manual that covered both oil line routing systems but I guess that wasn't good enough and since we are thousands of miles apart I can't hold your hand to open the manual the best I can do is tell you that your Sportster oil tanks have:
1. Feed line from the bottom of the oil tank to the oil pump 3/8"
2. Return line from the oil pump to the top of the oil tank 3/8"
3. Vent line from the top of the oil tank to the gearcase 5/16"
If you have an aftermarket oil tank with 4 ******* I can't help you. You will need to do some R&D on your own.
You are welcomed to send me photo's of your tanks so I may be enlightened to your dilemma. xlch@mail.com
Good luck and have a wonderful day.

I need routing diagrams for both gas & oil lines for a 1990 HD XLH883H Sportster


Contact me directly at wd4ity@bellsouth.net and I'll send you a drawing for the oil lines. The fuel line simply runs from the petcock to the carb between the cylinders. Nothing special about it's routing.

Need diagram for 87 heritage softail oil line routing


The tank has four lines on it. The large line on back side of the tank is the oil drain line. The lowest oil line on the bottom of the tank goes to the feed side of the oil pump. The oil comes out of the other fitting on the pump and goes through the oil filter. It goes to the outer edge of the filter. The oil comes out of the center of the filter and goes back to one of the upper nipples on the tank. There is a vent line that comes out of the case just behind and above the oil pump that goes to the other high nipple of the tank.

If you can't figure out which fitting is which on your oil pump, jack the rear wheel up and put the transmission in high gear, remove the spark plugs. Then, using a oil squirt can, fill the fittings with oil. Turn the rear wheel in the normal direction of rotation and watch which fitting spits the oil out, this is the return side of the pump and the other side is the feed side. Depending on how the oil pump is set up, the feed fitting is the one closest to the centerline of the bike usually. But, It depends on how the pump is set up. If it only has one fitting on the pump outer plate, that is the feed fitting.

Good Luck

Does anyone have a diagram for how the oil lines run on a 1970 ironhead sportster with an oil cooler?


You '70 model has the "long" style oil pump on it. It has a inlet and an outlet. Of course, the hose from the bottom of the oil tank goes to the inlet. From the outlet of the pump, route your oil line to the oil cooler. Then from the oil cooler back the top of the oil tank where the cap goes on. The oil filter is inside the tank under the cap. There is also a vent hose that comes from just in front of the front chain sprocket that goes to the small nipple on the oil tank. This is the way most people run the oil lines.

I am replacing the stock oil lines on my 02 883. I forgot what the oil route is from the pump. I know that there is 2 lines on the bottom of the pump and one a little higher. One of the bottom ones goes to...


An oil line routing diagram is in the factory service manual. Screw the oil filter off, remove your spark plugs, and spin the engine. If oil pumps out of hose going to the oil filter, you pump is working fine. If you do not have any oil pressure, your tappets will rattle badly. You'll know it.
