IC.6.1 Low Pressure Injection (LPI)

Low Pressure fuel injection systems are those functioning at a pressure below 10 Bar. Most Port Fuel Injected (PFI) fuel systems are low pressure.

IC.6.1.1 Any Low Pressure flexible fuel lines must be one of:

 Metal braided hose with threaded fittings (crimped on or reusable)

 Reinforced rubber hose with some form of abrasion resistant protection IC.6.1.2 Fuel rail and mounting requirements:

a. Unmodified OEM Fuel Rails are acceptable, regardless of material.

b. Non OEM fuel rails made from plastic, carbon fiber or rapid prototyping flammable materials are prohibited.

c. The fuel rail must be securely attached to the manifold, engine block or cylinder head with brackets and mechanical fasteners.

Hose clamps, plastic ties, or safety wires do not meet this requirement.
