High Pressure Line

The high pressure line is stainless steel tubing with matching high pressure O-ring Face Seal (ORFS) fittings. The individual tubes are pre-formed with fittings installed. All O-ring face seal fittings use nitrile rubber O-rings and might be identified with a yellow or white band. These O-rings must be replaced with the correct replacement part whenever a line is opened.

When installing NPT (pipe thread) fittings DO NOT use Teflon(R) tape. Tape fragments could lodge in a regulator and allow fuel pressure to exceed specified levels. The use of pipe sealant with Teflon(R) is required.
