This fuel line is made of chrome-plated, seamless copper tubing and is double flared at the outlets. This braided stainless-steel line offers rugged billet-style construction and AN aluminum fittings. The center-to-center distance measures 9.250, it has a 5/8-18" inverted flare inlet, and is tapped 1/8" pipe thread for a fuel pressure gauge. The strong tubing resists bending and twisting so it is ideal for any street rod, racecar, or ordinary street car.
