I have never been a fan of the hard lines.  Something about using friction to hold a line that is pumping a slick fluid.

My 1992 needed to have all the rubber lines replaced anyway, so, I changed my filter mount and put barb fittings in.  Replaced the hard lines with rubber ones.  No worries....

I think that is return oil.

Look for the possibility of a collapsed or plugged filter, also the possibility that the filter is connected backwards.
In addition to the possibility of a pinched hose in the return circuit that might cause over-pressurization.

All spin-on filters should be connected so oil enters the filter on the outer passage and oil exits Via the center.
Easy to check by removing the filter and cranking the motor to see how the oil flow is routed.

it was the outer one on the filter housing that blew out , yes should've did barbs , so the outer line on filter housing should come from where ? and what size threads are those 7/16 ?

The line that goes to the outer passage should be oil into the filter.

If it is hooked up backwards (oil into the center) an oil filter with a good anti-drainback valve will block flow and blow off lines (or sump running).

There should be very little pressure in the return, lots of flow with about half of it air.

If you have it connected with oil from the pump into the outer passage and clean oil out the center of the filter to the tank and it blows off a hose there is a good chance you have a bad or plugged filter.

Remove the filter and crank the motor briefly, oil should show from the outer passage of the filter housing not the center.

I can't speak to HBKeith's FXR, but on my Softail, it is almost impossible to route the hard lines backwards. They have bends in them that will only line up with the fittings in the oil pump and filter bracket as they are intended to. I have to say I am no fan of these hard lines. A real PITA to deal with, especially when working on with motor in frame. I had to remove the oil pump outer cover to even get the oil lines in/out. I also found out the hard way, DO NOT go crazy tightening those expansion fitting nuts on the oil lines. Else, indeed, they will leak. Just like the smaller version on Shovelhead/Ironhead top end oil lines.

JW , i know what you mean about how the hard lines route but I swaped engines , oil tank out , new lines etc. i made a oil line  diagram when i pulled it apart of how they went and if i remember correct ( usually i don't) it seemed diferant from my HD Manual. got some hose barbs tonight , gona put it on lift and check things out this weekend , pull the filter .been working 12 hour days

At the bottom of your engine case is a allen plug, drain the sump, inspect for metal in the oil, while it's on the lift.

Vaguely remember that the manual schematic is wrong and will leave you scratching your head because if you follow it the hard lines donít fit proper. Itís misleading.

     it is confusing , the way the hard lines lay out the line from bottom of oil pump goes to inner hole on filter housing ( its how mine is ) ,my HD service manual shows bottom of oil pump to outer hole .

IIRC you have a Ultima motor, go by the diagram that came with the motor.

oil goes into the filter via the outside holes and come out the centre hole

In on the out / Out on the in

92 FXR 113 Ultima.finally slowed down at work , bike making knocking noise from compensator area after I changed oil , fixed line etc ,good oil pressure , no metal from oil . so now i pulled primary cover ,comp and primary chain seemed little wore, put on a used compensator a buddy had and the noise wasn't as bad , so got new compensator new primary chain , put back together sounds pretty good , 10 mile ride and its back to loud again  :wtf: listen to it with stethescope noise sounds to be from compensator . crank bearing make the comp loud ? thoughts on this EL Broke 0 113 . will ad that when first fired this bike up after getting it built the first time , everything thing was very quite. the morning I blew the oil line out I thought I heard a faint rattle in comp/lower end area . also will ad , Comp and clutch assembly  upgraded to 98+ , 92 FXR chain when bike was built

Try a plain sprocket and see if the noise goes away (comp delete)

Did you check for metal in the oil? That will show if there is a bearing problem.

I hear ya , I just find it hard to believe out of 3 comps ( 2 known good used ones and 1 new one ) that all 3 make noise .
