Oil light stays on.

Appears it is the idle fix for the light and anti-drain. If you look at PDF Page 2 closely. The ball check is overridden at speed. Later models are under the filter just for the light and the pump has the anti-drain there.
When you put a restriction in a line, it increases pressure. It does this by a loss in flow volume. At low idle speed, the pump doesn't have enough pressure without that slight restriction.
bet if your bike set a long time, the oil bag is emptied.
My old Softail if it sets much over 4 months, bag empties because the o-ring in the pump is worn I guess. It takes quite a few blocks of low-speed running to refill bag since it's also pulling oil out.
That oil pump design was used 59-69 and on a limited amount thru 76

What did you end up sealing the spring housing with? There is a few overall kits by different makers that use a hard black ring. Probably same kits from China.
If you thread was straight, I still believe it was originally a thin hard red fiber ring like one you see in fittings that come in carburetor overhaul kits. There usual only about 1/32 thick.
That would not affect spring tension and that type let's fittings lock tight.
It's pipe threads. It's NPS (National Pipe Straight) however, not NPT (National Pipe Tapered).
