Transmission vent


Not sure which end of the vent hose you're asking about, so I'll cover the whole thing.

The transmission vent line is off the top of the transmission:

(Note, the UPPER of the two pics)

It's routed along the top of the oil tank (under seat) and doesn't hook to anything. Just point the end down a bit so water doesn't run into it on a rainy day or when you wash the bike. This is a 3/8 id hose:

1972 shovelhead oil routing


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.

I have a 2006 harley sportster custom and have been told my oil pump has gone out and am wondering where the oil pump is located.


Follow the hoses from your oil tank There are 3 ports on the bottom of the oil tank. The feed, vent and return. The feed hose routes oil from the feed port at the lower right front corner to a fitting on the oil pump. The return hose comes from the oil pump back to the return port on the tank. The vent hose vents out the bottom of the frame.

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.

93 Fatboy oil leaking from vent tube at air filter. oil level is good, not over filled, oil will cover the oil tank on a 100 mile trip


On your '93 model, the crankcase vent is down low on the engine behind the oil pump and it runs up to the air filter through a metal and rubber hose. I don't know how many miles you have on your engine but it you're getting any blow-by on the rings, this will increase the pressure in the crankcase. Most people simply re-route the crankcase breather underneath the bike and plug the hole on the backside of the air filter. Replace the metal line with a rubber hose and put a small filter in the end of the hose. Route the hose back behind the transmission and attach it to the transmission mounting plate just in front of the rear wheel.

This was the way the older Shovelheads were done from the factory for years until the EPA made them start running the crankcase vented air through the engine. In 1994, Harley went to the "head breather" system and moved the crankcase vents to the heads. Still, the oil mist in the vented air builds up in the air cleaner on these models as well.

Good Luck

1988fxstc. Oil is blowing out of what looks like a oil tank vent hose that ends down by the rear tire. This is not the drain hose, but looks like a venting hose that is open near the rear tire. Anyone...


Without seeing the bike, I would guess that this is the crankcase vent. Originally, the crankcase vent tube came up from behind the oil pump and went to the backside of the air filter. A lot of owners changed the routing of this hose due to oil being blown into the air filter. They simply remove the metal part of the tube and replaced it with a short open ended hose running back and ending just forward of the rear tire.

As for the oil blowing out of the tube, it depends on how much oil blows out of the tube. If it's just a mist that will sometimes coalese into a droplet, this is about normal. But, if it's a steady drip or flowing oil, this is not right.

If the mist is heavy, this could be caused by excessive blowby on the rings creating high crankcase pressures. The use of synthetic oil should not increase the blowby unless the rings are in poor shape, then it will. The use of synthetic oil seems to aggrevate any minor leak turning it into a much larger leak.

If the oil is coming out in a steady stream or pumping the oil out of the engine, you proabably have sheared a key in the scavenge gears of the oil pump and it's not pumping the oil back into the oil tank.

Now there is a vent hose on the oil tank but it should be routed to a fitting on the crankcase that is located just above and slightly behind the top of the oil pump.

Good Luck

My harley has a small leak coming from the air filter, the mechanic at the harley dealership told me it was the air filter. So i bought a new filter put it on and checked the oil level, with the bike...


Regrettably, a small oil leak from the air cleaner assembly is "normal". This is because the EPA requires all crankcase emissions to be routed to the intake system so that it can be burned in the engine. The result is that oil mist in the crankcase vented condenses in the air cleaner and eventually drips out.

The crankcase vent for your Sporty is in the heads. If you noticed, there are two large bolts that are hollow holding the air filter backing plate on. The crankcase vents into the air cleaner assembly through these two bolts. There is an "unbrella valve" in the rocker box center section that allows the air to flow one way but not the other. There are baffles in this area to keep the oil mist to a minimum but still there is some in the air coming out of the engine.

There are a few kits available on the aftermarket for re-routing this crankcase vent. You can direct the exit anywhere you wish using one of these kits. Most people just route the hose down and exit it under the bike just in front of the rear wheel.

When adding oil to your bike, only add the oil when the engine is hot. On your dipstick, you have two marks. The upper mark represents "FULL HOT" while the lower mark represents 'FULL COLD", Do not overfill. Check the level with the bike on the side stand.

Good Luck

Took tank off and didn't mark hose know don't know they go


all main fuel lines should route to the fuel filter first. then to a "fuel pump" system, then up into the fuel rail or t-fitting. if you see a smaller extra hose coming off the tank that is just a purge vent tube overflow line. That should drain into another funnel like collecting device that will route to it so as to not drop onto the hot running engine. Follow the main line from the fuel selector on/off/res... there better only be one line... or that means you"ll have two fuel filter/ pump systems, i wouldn't want straight unfiltered fuel going directly into my carbs. (Plus that would mean your pump and main filter are in the tank) this could be a possibility!! Let me know if im wrong, call the dealer and ask, but this is 1993 technology not 2003 it should be very basic.
