Product Description

Save shop time with our pre-formed stainless steel fuel lines, by eliminating bending, cutting and flaring. Original fuel lines typically require replacement due to rust from moisture and corrosive road treatments. Our OE FIX addresses this common failure, by upgrading the fuel line material to stainless steel to resist rust and corrosion. Additionally, the pre-formed sectional design reduces installation time, ensuring an exact fit, adding another layer of convenience.
