===== Oil Lines =====
The OD of the oil & vent lines is as important as the ID. ((IronMick of the XLFORUM http://xlforum.net/forums/showthread.php?t=563241&page=2)) \\
If you buy automotive lines that are larger OD, they will be difficult to run in the limited space and easy to kink. \\
Oil lines for 59 and up: \\

Feed and Return: 3/8" ID X 5/8" OD reinforced rubber. \\
Vent: 1/4" ID, 1/2" OD reinforced rubber. \\
The tank is vented to the cam chest because, it applies a slightly negative pressure to the tank. ((ryder rick of the XLFORUM http://xlforum.net/forums/showthread.php?t=600218&page=2)) \\
This promotes the evacuation of condensate from the tank and keeps the tank from being pressurized. \\
(by the air that is also returned by the scavenge pump) \\
General oil line routing on AMF Sportsters: \\
The vent and the return lines route under the starter and solenoid. (can't run over them since the exhaust is there) ((74XL of the XLFORUM http://xlforum.net/forums/showthread.php?t=80209)) \\
Use care under the starter as to not kink or flatten the lines (rubber or copper) ((garbiker of the XLFORUM http://xlforum.net/forums/showthread.php?t=80209&page=2)) \\ 
Feed line runs out the bottom of the oil tank, close to the chain, around the swing arm and under. \\

Feed line at the chain: \\
There is a steel bracket that holds the oil line in position. ((Hopper of the XLFORUM http://xlforum.net/forums/showthread.php?t=80209&page=2)) \\
It mounts onto one of the rear engine mount or case bolts and keeps the line away from the chain.\\
The bracket is a piece of .060" sheet metal about 3/4" wide and maybe 3" long with a hole in one end where the bolt passes through it. \\
The other end is bent in a half circle that fits over the oil line and holds it against the frame / engine. \\

77-85: \\
The oil return comes off the front of the oil pump, not the top of the case like earlier years. \\
Essentially you have the following lines: ((ericfreeman of the XLFORUM http://xlforum.net/forums/showthread.php?t=600218)) \\
Feed: From the bottom of the oil tank to the rear fitting (inlet) on the oil pump. \\
Return: From the top of the oil tank to the front oil pump fitting close to the pressure switch. \\ (perhaps after going through a cooler) \\
Vent: From the top of the oil tank to the 1/4" hose nipple on the upper backside of the cam cover in front of the sprocket. \\


===== Connections at the Oil Tank =====


There are generally 4 holes on all early style oil tanks. ((Ferrous Head of the XLFORUM http://xlforum.net/forums/showthread.php?t=1313106&page=3)) \\
Two near the bottom of the tank and two near the top. \\
The feed line will be near the bottom and the return line near the top. \\
These two lines will be bigger than the other two. \\
The smaller line at the bottom is the chain oiler (often not used and blocked off or just turned off). \\
The smaller line at the top is the vent for the tank. \\
(on early engines it runs to the top of the case just behind the rear cylinder) \\
There are internal drilling to route the vent into the cam chest (which vents to atmosphere). \\
On later engines it runs down to the cam cover which has a 90° fitting to accommodate it. \\

In a horseshoe tank, the return oil should go to the far side so that oil has to migrate from one side of the tank to the other to get picked up again. ((ryder rick of the XLFORUM http://xlforum.net/forums/showthread.php?t=600218&page=2)) \\

This tank is pretty straight forward. ((photo by knotwerk of the XLFORUM http://xlforum.net/forums/showthread.php?t=563241)) \\ 
Top (2) fittings are vent and fill. \\ 
Bottom fitting is supply to the engine. \\ 
It also has no drain fitting. \\ 
{{:techtalk:ih:oil:67_oil_routing_2_by_knotwerk.jpg?direct&300|}}

On this one (on a 74 XLH), the vent is higher than the feed and return lines. ((photos by vyper202 of the XLFORUM http://xlforum.net/forums/showthread.php?t=1570042)) \\

===== Connections at the Oil Filter =====
The oil filter (HD 63782-80T) is the small one that is usually used on custom bikes. Chrome or black can be found. ((IronMick of the XLFORUM http://xlforum.net/forums/showthread.php?t=563241)) \\

It is also commonly known that the more oil you hold, the more motor heat can be transferred to dissipate that heat. \\
Race bikes have huge oil tanks for that reason. ((Monte03 of the XLFORUM http://xlforum.net/forums/showthread.php?t=563241)) \\
If you go the filter route, be sure to purge the lines by bleeding the pump front nipple first while running. \\
Then take the return line and place it into a pail before you connect to the barb tank fitting so you assure a complete circle has been made.

===== Connections at the Engine =====
Early Sportsters had the lines route to the top of the case. ((Monte03 of the XLFORUM http://xlforum.net/forums/showthread.php?t=563241)) \\
Later the MoCo routed a line directly to the back of the oil pump. \\

There is a transmission vent on top of the case in the area near the starter solenoid. ((IronMick of the XLFORUM http://xlforum.net/forums/showthread.php?t=563241&page=2)) \\
This one should just vent to atmosphere, either up attached to the frame, or down aimed to ground. \\

===== Oil Lines to the Rockers =====
If you have a leak here, you may not have to replace any parts. \\
Try to uninstall them, clean, inspect and reinstall them and see what happens. \\
Note for reinstalling the metal oil lines; ((IronMick of the XLFORUM http://xlforum.net/forums/showthread.php?t=1974660)) \\
The line is just long enough to be inserted a small amount at each end at the fittings. \\
So insert at the top, then the bottom ensuring that it is more or less even from top and bottom. \\

You can install the rubbers an inch or more from the line ends. \\
Then, while keeping it from shifting, slide the rubbers into place. \\
 \\
Then slip each line-end in place, and hold it there while sliding the rubbers into final position. \\ 
Tightening the nuts will seat the rubbers. Light grease on the rubbers will help. \\
Tighten them alternately, again keeping it from shifting.

Keep an eye on which style you buy (if any need replaced). ((hcrashsterof the XLFORUM http://xlforum.net/forums/showthread.php?t=1974660)) \\
The OEM is barrel shaped. \\
Some aftermarkets are a barrel with 45° cuts on the top and bottom. \\
The 45° ones are no good. \\
Either a different polymer is used or you really need that full barrel shape to seal the oil line properly.

===== Copper, Brass and Stainless Tubing =====
These were made with flared fittings and are a positive seat fitting. \\
They do not allow for any growth once the motor gets hot (if that's a concern). ((Monte03 of the XLFORUM http://xlforum.net/forums/showthread.php?t=1793589&page=2)) \\
The OEM style tubing uses slip compression type fittings which will allow expansion. \\
However, the flared fittings have been used on Sportsters. \\

==== Stainless Steel ====
Stainless steel tubing will polish up like chrome and does not rust. \\
You can also use Parker stainless steel fittings and 1/4" tubing. ((Bustert of the XLFORUM http://xlforum.net/forums/showthread.php?t=1793589&page=4)) ((http://xlforum.net/forums/showthread.php?t=1793589&page=5))  \\

They will come with compression fittings, DO NOT USE!!!! \\
On the bottom fitting. \\
On the upper fitting, drill the 1/4" hole to allow the tube to slide up into the rocker box. \\
There will still be a slight taper left. \\
This will allow you to insert the tube into the rocker box and then down into the bottom fitting stop. \\
You can cut pieces of fuel line hose to make the seal rings as it will resist the oil and heat. \\
You can use O-rings here if you have them also. \\
