Need to know oil line configuration for 95 softail custom . which oil lines run from pump to oil tank,oil tank to filter etc.

The oil line routing for a 1992 Harley-Davidson Ultra Classic Electra Glide can vary depending on the specific configuration and any modifications that have been made to the motorcycle. However, I can provide you with a general guideline for the oil line routing on this model:

1. Oil Pump to Oil Filter: There should be a hose connecting the oil pump to the oil filter. The oil pump is typically located on the bottom of the engine, while the oil filter is usually located on the front or side of the engine.
2. Oil Filter to Engine: Another hose should connect the oil filter to the engine. This hose delivers the filtered oil from the oil filter back into the engine.
3. Oil Tank to Oil Pump: The oil tank, which is usually located underneath the seat or in the saddlebags, should have a hose that connects to the oil pump. This hose allows the oil to be drawn from the oil tank into the oil pump for circulation.
4. Breather Lines: There may also be breather lines connected to the engine and oil tank. These lines help to release excess pressure and prevent oil leaks.

It is important to consult the motorcycle's service manual or seek assistance from a qualified mechanic to ensure the correct routing of oil lines for your specific model. The service manual will provide detailed diagrams and instructions specific to your motorcycle's year and model, ensuring proper oil flow and system functionality.
Additionally, be sure to check for any specific oil line routing guidelines or modifications from aftermarket parts or accessories that may have been installed on your motorcycle.

The way to tell on Harleys is as follows (with explanations).



If you pull the oil lines one at a time, the following will happen:

On the oil return, and the vent line, oil will not flow out (except maybe a little residual oil).

On the feed line (oil tank TO oil pump), oil will flow out, especially it the oil cap is removed!

NOW, if you\'re asking because you want to install an inline oil filter or oil cooler, the feed line IS NOT the one you want to install this on!!!



Why?



The feed line is gravity fed to the oil pump, and there is no pressurization in this line, and the line could cavitate (suck air), especially if the filter/cooler are mounted too high!



The RETURN line is where you want to install these items, as this line is pressurized with the engine running, forcing the oil through them on the way back to the oil tank.



So which is the vent, and which is the return?



Pull the two lines you have already identified as NOT being the feed line (as described above), start the bike and run for ONLY about 5-30 seconds (or however long is needed), and see which line has oil coming out of it under pressure.



THIS is the line to install an oil filter and/or cooler.

Technically speaking.....NONE!

In reality, an oil line runs from the oil pump return line fitting to the oil filter, and FROM the oil filter TO oil tank return line fitting.

Could be a couple of different things.

First off, check your oil level....is it correct? (I know, kinda stupid of me, but I had to ask)

Just because you have oil doesn't mean the oiling system is working.
On thing you can do is remove oil tank cap, using a flashlight look down into the tank and see if you can notice oil being pumped back into the tank.
Or, you can pull the oil sending unit and see it oil pumps out the hole when the engine runs (this WILL be messy!).

Or, pull the oil return line at the oil tank.
IF you pull the feed line by mistake, you'll know!
Oil will run out the tank fitting until the tank runs out of oil! (opps, wrong line!)
When you pull the return line, you should get just some residual oil out the tank fitting (and the line).
Put the end of the line in a container and see if oil squirts out when the engine runs.

If all the above indicate oil IS circulating, the oil sending unit itself might be bad. They do occasionally go out.

Bottom of oil tank to right/outside feed on pump. Inside is return line to top of tank where filter cap is. If you ran a cooler than run this line to the cooler and back to the tank. Above the pump is the large vent line. It goes to a tee fitting and than to the top of the tank and to the back/bottom of the primary. The small line goes to the back /center of the primary. It\'s the chain oiler.

Ok, let me brush some cobwebs off here and see if I can remember how the lines go on the FXR. On that model, the oil tank was under the seat and one line off the bottom of it and two at the top as best as I can remember. Of course the line off the bottom of the tank was the feed line and goes to the inlet of the oil pump. As best as I can remember, the oil pump had one fitting in the middle of the outer plate on the oil pump. This would be the inlet. If the fittings are on the top, the outer fitting is the inlet. The outlet from the pump was under the cam chest facing towards the front of the bike. A metal line ran from it to the oil filter and another line ran from the oil filter back towards the tank. The line changed from a metal line to a rubber line right about even with the oil pump and then it went up to the large fitting at the top of the tank. There was another oil line that came from the cam chest just above and slightly to the inside of the oil pump. This is a vent line that goes to the top of the oil tank. The crankcase vent comes from a fitting below the pump and to the inside and runs up and into the backside of the air cleaner. This is the best that I can remember on that model. 1986 was a long time and a lot of bikes ago. Remember, the oil comes from the tank to the pump, into the engine out of the pump through the oil filter and then back to the tank. If you have trouble figuring out the pump connections, Squirt a little oil into one of the fittings and spin the engine with the starter. Watch the oil, if it goes into the fitting, that's the intake. If it blows it back out, it's the outlet. If you have any problem, contact me directly and I'll make a drawing or something to send you.

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.

To the best of my knowledge, your Duece takes three quarts of oil with a filter change. The transmission holds 20-24 ounces of oil. And, your primary takes 38-44 ounces of oil.

Your oil tank has a dipstick in it. Fill the oil tank until the level is just above the lower line with the bike on the stand. The lower line is "FULL COLD" and the upper line is "FULL HOT". Do not overfill.

The transmission is the same way, On the right side clutch release cover, there's a plug that takes a 3/8" Allen or Hex key to remove. It too has a dipstick marked the same way the oil tank dipstick is marked. Check the oil in the transmission with the bike standing straight up.

In the primary, you fill the oil level to where it just touches the lowest part of the clutch spring. The outer clutch housing is bright aluminum. Inside this is a round dark colored piece of metal. This is the clutch spring. Fill or check the oil with the bike standing straight up. Do not overfill as it will make your clutch drag and you will not be able to find neutral with the engine running.

Good Luck

Get this manual online at www.reliable-store.com and get complete guide on whether to repair or not, service it, and how to repair etc, along with wiring diagrams, electrical diagrams, torque specs, error codes, everything.

No expert on newer Hogs but try this.If tank is replica of wrap-around type look on flat right-rear bottom over rear pipe.Just a flat bolt-head.Yep,it's messy,cover the pipe.Like I said,no expert. Follow bottom most oil line from oil pump back to oil tank. Maybe it "t's" off under frame into line that drops down toward ground. You could get a catch pan under there.I vote for the nut on tank.Wrap around,you know, the battery is in it.
