Oil Pressure Line Leak

Hello Gang,

Here's the deal,


On my 1997 GMC Jimmy I noticed an oil leak. The location of the leak is on 4 lines at or near the oil filter. It appears there are two lines coming into the oil filter as well as two additional lines in the same general area. I really have not traced the other two lines, however the lines are rubber, with what looks like compression fittings on the ends which transfer over to soild aluminum tubing. It looks like the rubber is begining to crack causing the leak.

I need to know what the part number on there lines (if known) and most importantly WHAT ARE THERE TECHNICALLY CALLED (for ordering purposes. And as for pricing and ideas???? and lastly, are they after market items and easy to install. Any feedback is greatly appriciated.


Thanks for everyones time and help!!
