"NEVER use Braided line for your oil pressure line. Steel or seamless copper."


Why not?

Depending on the line you choose, safe working pressures are 1500 or 2000#.

All the drag race guys I know use the stuff.
Some of these cars run in the high 7's, low 8's.

My street roadster runs braided oil pressure lines.
#10 to the remote oil filters, #4 to the oil pressure gauge and #6 to the trans cooler set-up.
Got some #8 in there as well. Those go to the fuel lines.

Never had a problem with the stuff and neither have my drag racing friends.

The only cautions I can see is, the stuff is a low speed saw so it needs to be adequately supported by clamps.
That protects both the line and the car's components.
(Along those lines, I've been watching a very nice Chevelle with big block that has the fuel lines draped from fender well to carb.
The braided stainless line rubs on the aluminum rocker cover and it looks like it won't be long until he strikes oil....
