This is our original design, backed by thousands of happy customers since 2018

With this handy pre-molded hose, you can custom fit your fuel and oil lines!  These really give your project a finished professional look, while avoiding kinks in tight spaces which cause flow restrictions. Available in J30R7 spec (3/16"-3/8" - 50 PSI working pressure, 1/2" 35 PSI working pressure), with popular sizes available in J30R9 (100 PSI working pressure).  Safe for use with gasoline, oil or E85.  The hose is molded to shape during manufacturing to include commonly needed bends.  Simply cut the portion out that you need to create 45, 90, 135, and 180 degree bends. Attach to a tube or hose barb in your application using appropriate hose clamps.
