Front mount oil cooler, rubber hoses? Options

[yarin]

Any comments?

Every front mount application i've seen uses Aeroquip braided steel lines. Is rubber a bad idea? Thanks

search on part numbers 5279k213 and 5440k113. I used 1/2" but you could go with 3/4 if you wanted to. This hose is awesome stuff and the barb fittings have nuts like the AN so they can be disconnected easily.

Brass Ball-Seat Hose Nipples

Assembled Nipple
A ball seating inside the nut of these nipples creates the seal, minimizing leaks that can occur with pipe thread connections. For easier installation, fitting consists of two pieces: a barbed hose stem and a separate NPSM (mechanical straight thread) female swivel nut. Just insert the barbed hose stem into the swivel nut, attach the hose to the stem, then swivel the nut onto the pipe connection. Swivel action during installation helps prevent hose from kinking. Maximum working pressure is 250 psi.
