With the regulator mounted, we built our lines from the tank. Here you can see their exit from the front of the tank behind the differential. The tank came with two 3/8-inch NPT female fittings, one for the feed and one for the return line. We used Earl's Ano-Tuff and Pro-Lite 350 hose to run the length of the car. We replaced the stock 1/4-inch line with -8 that has a 1/2-inch id. An ignition-armed, positive 10-gauge wire and matching 10-gauge ground is all the tank needs to run.
