AN8 PTFE hose with a stainless steel braid, supplied per foot. AN8 is where you move once fuel demand outgrows AN6, and it is also the common choice for oil cooler and gearbox cooler runs. The PTFE liner gives zero fuel permeation and full compatibility with ethanol and methanol blends, and it holds up to sustained hot oil without softening. The stainless braid protects the liner from chafe and keeps the hose from expanding under pressure, which helps maintain stable fuel pressure at the rail. PTFE hose is stiffer than rubber, so allow for a wider bend radius when planning the route, and use AN8 PTFE hose ends.
