4AN PTFE Braided Hose / Line (E85 + Race Fuel Safe) - BY THE FOOT

Building custom fuel, oil, coolant or brake plumbing on your 1988-1998 Chevy/GMC C/K (OBS/GMT400) truck? This ColorFittings hose / line works on 2WD C-series and 4WD K-series 1500, 2500 and 3500 pickups, plus GMT400 Suburban, Tahoe and Yukon builds.

ColorFittings PTFE Braided Hose delivers zero-permeation, high-pressure fluid transfer for fuel, oil, coolant, brake, and power steering systems. The smooth-bore PTFE liner resists chemical attack from E85, ethanol blends, and race fuel — fluids that break down standard rubber hose over time.

Fuel/fluid compatibility: gasoline, E85, ethanol blends, race fuel, motor oil, coolant, brake fluid, power steering fluid.

Available in Stainless Steel, Black Stainless Steel, or Black Nylon braid — same PTFE liner and performance in each. Sold by the foot; order the exact length you need. Pairs with matching PTFE hose ends and Hose Separators.
