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:
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.
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.
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.
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.
need to clarify your statements
you say-- have replaced flexible lines from the tank to the engine --replaced the primer bulb
well that is all the rubber hoses from the tank to the pump on the engine
Then you further state only parts not replaced are the connections between the
gas tank and the motor and the tank itself
Well that connection is the rubber hoses that you stated were already replaced
So this may help rubber in outboard motors rots internally so replace all rubber from the tank to the motor, overhaul the fuel pump on the motor and all the rubber hoses from the pump to the carby/s
the primer bulb will not pump fuel if the tank vent is not open so that is one reason you feel like it is pumping air when priming
best advice is --no e-mix fuels to used on out board engines
Those motors have a sensor on the oil pump drive gear that senses the oil pump drive shaft spinning. That sensor could be going out giving a false code. You can take off the oil line exit on the pump and crank the motor up for no more than a minute to check for oil flow. It won't be much at all....a dribble is all you can expect on idle. The most common problem is the oil tank on the motor itself or the sensor probe in the tank. The float can fall off giving a false signal as well. Make sure the cap and hoses are tight on the remote oil tank as the motor pressurizes the tank to push oil to the motor reservoir.
You need to look into the oil tank with the engine running and check to see if your oil is being returned back to the tank. If not, you probably have sheared an oil pump drive gear key. If the oil is pumping back into the tank, everything is fine. If you can't see the oil coming back into the tank, disconnect the oil return line, take the spark plugs out of the heads, and spin the engine with the starter. OIl should come out of the hose in squirts. If not, you have an oil pump problem. If it does come out of the hose, everything should be alright.
Harley engines are noted for "no oil pressure when idling hot". The system is a high volume low pressure system. This is because of the use of roller bearings on the crank pin instead of insert style bearings. Don't let an oil pressure gauge scare you.
Sportster = At the back, oil tank drain hose connected to a nipple on the frame with a hose clamp.
Twin Cam = Under the motor you'll see 2 plugs, one vertical and one horizontal.
the vertical bolt is the oil drain plug. The horizontal bolt is the Transmission drain screw.
Evo = Back of the bike, oil tank drain hose connected to a nipple on the frame with a hose clamp.
Some may be modified and just be a hose with a bolt stuck in it with a hose clamp.
Removal & InstallationTo Remove: WARNING To avoid being burned, do not remove the radiator cap or surge tank cap while the engine is on or is still hot. The cooling system will release scalding fluid and steam under pressure if radiator cap or surge tank cap is removed while the engine and radiator are still hot. CAUTION If the vehicle's coolant is low, drained out, or has repeatedly needed coolant or water added to the system, then the system should be completely flushed.
Before servicing the vehicle refer to the precautions at the beginning of this section.
Drain the cooling system.
Remove or disconnect the following:
Inlet hose from the radiator
Radiator outlet hose from the radiator
Lower fan shroud
Surge tank hose
Vent inlet hose from the radiator
Surge tank hose
Engine oil cooler lines from the radiator
Transmission oil cooler lines from the radiator
Remove the radiator
Radiator bolts
Radiator from the vehicle
To Install:
Install or connect the following:
Radiator to the vehicle
Radiator bolts and tighten the bolts, Torque to: 18 ft-lbs (25 Nm)
This is what we call "oil sumping" around here. On the soft tail line or any other line of Harley where the oil tank is higher than the oil pump, the oil will seep past the check ball in the oil pump and leak into the crankcase of the engine. When the engine is started up, it will "puke" the oil out. Now, up until the introduction of the Evo engine, the engine would puke on the ground under the bike out the breather tube. Now with the Evo engine and the EPA's regulation that crankcase ventilation fumes have to be fed back through the intake, it pukes into the breather. An even bigger mess. So, what we do whenever we think we've got this situation is put a pan under the shovelhead and panhead bikes, On the Evos and Twin Cams, we take the air breater cover and the air filter out before the fire the engine. It's a mess either way you look at it. I don't think the Twin Cams are as bad as the Evo engines due to the different type of oil pump.
