Depends on what look you want. SummitRacing sells nice braided line and connectors to do it pretty. You need 3/8" and 5/16" hose and connectors available in the DORMAN product line at your local auto parts store. Be sure that if you use rubber hose that it is fuel injection rated hose. The 3/8" MUST be quality rubber or braided hose since its under constant pressure. If using rubber hose, do not use worm gear type hose clamps, get the band type with the nut and bolt through them so you don't destroy the rubber sheild on the hose.
