Other hose is available from EARL'S besides the standard stainless steel covering. The Pro-Lite 350 hose is covered by a tough abrasion-resistant Nylon sheathing, bonded to the textile inner braid embedded in the synthetic rubber liner. This hose is much lighter then the standard Perform-O-Flex stainless hose. According to EARL'S, replacing the existing steel braided oil, fuel and coolant lines on a Cup car can save as much as 30 lb. Also, the stuff looks cool!
