Oil Pressure Plastic Line - what a joke

[lks dcvn]

So I was looking over my dash wiring last night in my Blazer and when I was putting the wiring back up in the dash - the plastic oil pressure line broke off the back of my dash gauge...(except...I didn't know it at the time).

You may know the end of this story...I went to put it back in the garage and as I moved it about 4 feet I got a dousing of oil on my foot, leg and carpet (the carpet is old and will be replaced at some point (carpet is in my basement waiting for time and decent weather).

The plastic line snapped off at the back gauge and I have the parts that hold it in still (ferule and pressure nut). Any tips on how to get the ferule back on the line so I can reattach it to the back of the gauge - I tried until dark last night (about 10 minutes or so) with no luck.

Any and all help appreciated. Thanks.
