Our PTFE hose has a PTFE core with an external stainless reinforcing braid and must be used with PTFE specific hose ends. PTFE is the most chemically resistant hose available and is compatible with all automotive fluids and fuels, including all race fuels, methanol, and ethanol, with the exception of acetone. PTFE hose has an infinite service life as the high density PTFE core cannot be permeated by automotive fluids. Unlike other types of hose, PTFE remains odorless which makes it the best choice for garage kept vehicles. A thin PTFE core contributes to a small outer diameter and an improved bend radius over typical rubber/stainless hose. Stainless reinforcement may increase vehicle NVH (Noise, Vibration, Harshness) in some applications.
Our FlexLP hose has an Elastomer Core, FKM internal liner, integrated stainless reinforcement, and black nylon external braid with a gray tracer. FlexLP hose is compatible with all automotive fluids and fuels, including all race fuels, methanol, and ethanol. The FKM internal liner is resistant to permeation by automotive fluids, so no smell is observed from the hose (like our PTFE hose), however depending on the type of fluids used and conditions, FlexLP generally has a service life of 5-7 years. The predominantly elastomer construction does not contribute to vehicle NVH (Noise, Vibration, Harshness) in most applications. We recommend FlexLP over our other types of Fuel Hose as FlexLP is the most user friendly and no noise or smell.
Our Starlite hose is Eaton Aeroquip's proprietary AQP (elastomer) core fuel hose with a flat black Kevlar and Nomex external reinforcing braid. Starlite hose is compatible with all automotive fluids and fuels, including all race fuels, methanol, and ethanol. It is the easiest to install and repair due to the lack of stainless reinforcement. AQP elastomer is permeable by automotive fluids, so expect a fluid smell from the hose. Higher alcohol content fuels will permeate more aggressively. Expect a 5-7 year service life (dependent on the fluids used and conditions). Elastomer construction will not contribute to vehicle NVH (Noise, Vibration, Harshness). We do not recommend using Starlite hose in a garage kept vehicle due to permeation and the resulting fuel odor.
