Oil pressure line tip/trick.
Was trying put my plastic line back in the fitting in the block but the small metal insert need to be opened up a little to fit the line through. I had pressed on a small rod and was trying to get it off when it flew across the workbench and out of sight. :mad F! I wanted to fire up my car and was not going to do it without my oil pressure qauge. Well after I was finished :cuss: my head off, I decided to figure something out. Well best I could come with was using part of a rubber vac port cap to seal it off. I cut off a piece about 1/8" long and used it in place off the metal fitting. Works geat! I used to get a very small amount of oil puddling around the top of it but now there is no sign of oil what so ever.

Re: Oil pressure line tip/trick. (Fevre)
Plastic oil lines are bad news. My brother had one either break, melt or get cut at the big end of Lapeer Dragway two summers ago. Fire and complete loss of oil pressure at 5,000 RPM/ 100 MPH is not good. He got new paint and I got what was left of his engine...Recommend changing to copper ASAP.

Copper is worse than plastic. It has a very high fatigue to vibration. Copper will crack and break faster than plastic. The best would be a braided line. I'm still running plastic but should switch to a braided line for safety

I haven't seen SS braided line & fittings that small. The fitting would be 2AN for a 1/8 in line.

Re: Oil pressure line tip/trick. (Robert N)
OK guys, I agree that the braided is probably the safest way to go, but I seem to be in the minority on copper over plastic. I also agree that for cracks due to vibration, the plastic is probably better. However, I've seen a lot more lines (not just oil pressure) that were cut, melted or chafed through (typically fairly quick failures) than were cracked from lack of vibration durability (usually a long term failure)....Thoughts?

Spoke a little too soon on the leak, have a little pool of oil again. Going to try to tighten it a touch more to see if that helps. Not ready to tear the car apart yet again si I am hoping I can keep it to minimum

Ok, kick me and call me stupid 
but I couldn't find a 2AN, 1/8 SS braided hose at Summit? Auto meter makes a "kit" but it changes the hose diameter to 3/16", and for $30....don't know if it's worth it. I like the idea of slipping a larger diameter vacuum hose over the 1/8 to control any ruptures. Will increasing to a 3/16" hose affect the pressure reading? :confused:
