We opted for the Autometer Mechanical with their braided hose kit. The hose is 6' and cost about $50. Meets the rule that spec's that you must use this type of material if you bring the line in to the gauge. If you go electric that is a different story and I would suggest a braided line from the block to a TEE on the firewall. Copper and Nylon are not suitable for racing applications.
