Can anyone tell me where to get the fural and nut to hook the oil pressure line upto the gauge? Its an 1/8 line but the fural you get at the auto part store dont work on it..

There are two stytes, the compression ring in a compression union for plastic lines, and a cone shaped style for metal lines.

Both can be bought at the local Hydraulic/Pnuematic Hose Supplier.

If it's a GM gauge, it doesn't use a compression sleeve - the factory gauge (and the fitting in the back of the block) use a GM-proprietary cone-type male and female fitting design that doesn't use a sleeve. Most aftermarket stuff uses conventional plumbing-type compression fittings with sleeves. Also, the factory nylon line uses tiny brass inserts at both ends for the line to compress against for a good seal when you tighten the fitting; Rick's has the correct factory line (with inserts) and the GM fittings. :thumbsup:
