PMO Fuel Pressure Control Unit — Adjustable, AN-6 Fittings | Carbureted Porsche 911 / 930 (PM-O404-0)

Same job, cleaner plumbing. The PMO Fuel Pressure Control Unit with AN-6 fittings (PM-O404-0) holds carburetor fuel pressure where it belongs, and does it on -6 AN connections so it drops straight into a braided-line fuel system without adapters or barb-and-clamp compromises.

Features

• Adjustable regulation — set the pressure your carburetors want and keep it there.
• AN-6 fittings — direct fit for braided stainless fuel line, no adapters needed.
• Prevents high pump pressure from forcing fuel past the float valves and flooding the bowls.
• Made in the USA by PMO.
