The Racor hoses are high end stuff. It’s 221FR fire resistant, UL rated for fuel and engine. They are cut-to-fit and use two piece Field-Attachable hydraulic fittings. Measure your length and cut with a cut-off wheel or hack saw. This is steel braided line and tough to cut. Be sure to blow out the hose after cutting. The Field Attachable fittings are very cool because you can reuse them, unlike crimped fittings. Our kit used JIC fittings at the filter and engine. These are the same high-pressure fittings that can be used on ram-assist steering systems.
