JEGS Pro-Flo 350 Series Racing Hose was developed to the strict specifications that racers demand. Nylon filament braided hose is lighter than traditional stainless braid hose. A vehicle equipped with dry sump oil system and electric fuel pump systems can realize a 25-30 lb. weight savings over stainless braid hose. That equates to a 2.5-3 HP advantage! Constructed from a seamless synthetic nitrile inner tube with an integral inner braid, high tensile nylon fiber outer cover that resists high pressure, temperature and abrasion for total reliability while remaining extremely flexible and budget friendly. A perfect complement for any Black, Polished or Electroless Nickel fitting combination. Compatible with all synthetic lubricants, most gasoline and alcohol-based or hydrocarbon fuels (although compatibility is not assured due to un-published additives currently used by fuel mfg in their blends), oils and coolants. Not for use with brake fluid, as vacuum line or in extreme heat situations.
