Oil line leak

This involves an Autogage unit plumbed to a port at the top of the filter on an LS1 adapt.
The poly line enters the port via a brass compression fitting. All was well until I glanced at the gauge-engine running, and noticed 0 pressure!!! The line had popped out of the fitting. Further attemps to fix, then re-tighten the fitting don't seem to be helping much. It doesn't take much to pull the poly line back out of the fitting.
I don't want an accident to occur while I'm on the road. With the high volume pump, it didn't take long to empty 3 quarts onto the garage floor.
Any ideas for a more secure fix would be quite welcome.
BTW, the line attached to the gauge itself (also compression fit) seems quite tight. Thanks.

I have a braided stainless line for my oil pressure gauge that I bought from AutoMeter......stays tight and also resists underhood temps rather well!!!

Re: Oil line leak

The poly lines should have a brass insert that goes into the end of the line. This is what keeps the line from collapsing when the compression fitting is tightened. Without the insert the line will not tighten properly. It will leak or pull right out....Jb.

Re: Oil line leak

The brass insert is a compression fitting.
If all are the correct parts it should work, it will leak, but the line should never be able to pull out between the couple if the compression fitting is doing it's job, and is the right size.
Go get a cheap sunpro gauge from autozone for the time being, the leak, but don't explode and dump oil everywhere.

Re: Oil line leak

Just get a copper line with the appropriate fittings, then you will never have to worry about the line getting cut, broken or coming out, it may cost a few dollars more but it is worth the peace of mind IMO.

Re: Oil line leak

The nylon lines that GM used seemed to be trouble free. The aftermarket gauge lines seem to be problematic. Copper or braided is a good idea, an electric gauge even better in my opinion.

I like this, Dave. Would you happen to know the part #, or where you bought this?

Re: Oil line leak

Everyone, thanks for 'steering' me in the proper direction.
I found some part #'s...
1)Autometer #3227 3ft braided w/1/8 npt fittings $43. @ Jegs & Summit
You can get the same exact @ ebay for $30. +ship/hand
2)Jegs offers 3 kits #41057/#41058/#41059 with varying lengths of braided 3ft/6ft for much less $ starting @ $24.
Now I won't have to worry about running my engine with 1 quart of oil!

Re: Oil line leak

Thanks, Dave! No apology needed. The part is 'in the mail'.

Clarification...I received the Jegs#41057 kit, then realized that the 1/8NPT fittings would not work on my AutoGage oil press line.
All of the above kits come with the 1/8NPT fittings.
So, per the suggestions given above, I ordered the 1/8" copper tubing kit with ferrules & fittings. I guess that the copper will not 'give' as the poly tubing did.
