Fitment Notes

• Compatible intake manifolds: 302 HO, 302 Truck, 351 Windsor Lightning, Explorer, Cobra, and GT40.
• This is an upgrade rail - OEM fuel injectors or OEM-equivalent injectors (same height, same upper and lower O-ring diameters) must be used. This is NOT a top-feed conversion rail.
• Fuel injectors are NOT included. Consult a tuner for flow rate recommendations and the injector manufacturer for correct dimensional specs.
• Compatible with all fuel types including gasoline, E85, methanol, and ethanol.
• Bosch EV1 injector connector adapters (17-0064, sold separately) may be required if injector interference with the lower intake manifold is present.

Features

• Large 5/8" internal bore maximizes fuel flow capacity to support high-power naturally aspirated and forced induction builds.
• Each rail features three 8AN ORB ports (six total across the pair), usable for inlet, outlet, regulator, pulse damper, or pressure gauge accessories.
• Innovative profile design maximizes distributor clearance while maintaining perpendicular injector orientation relative to the lower intake manifold - no spacers required.
• CNC-machined from 6061 aluminum, black anodized and laser etched for a durable, high-quality finish.
• Ports also tapped for 1/8" NPT fittings, adding gauge and sensor mounting flexibility.

Specifications

• Application: Ford 302 HO / 351 Windsor EFI engines
• Rail Type: Upgrade rail (OEM-style top-feed injectors retained)
• Internal Bore: 5/8" (large flow)
• Ports Per Rail: 3x 8AN ORB + 1/8" NPT (6 total across pair)
• Material: CNC-machined 6061 anodized aluminum (black)
• Sold As: Pair (LH + RH)

Included Components

• 2x Black anodized laser-etched aluminum fuel rails (LH + RH)
• Black anodized aluminum fuel rail mounts
• Black oxide stainless steel 1/4"-20 screws

Product Description

The Radium Engineering 20-1302 is a pair of high flow CNC-machined fuel rails designed for EFI Ford 302 HO and 351 Windsor engines across a broad range of Ford, Lincoln, Mercury, and Panoz platforms. Featuring a 5/8" internal bore, these rails flow significantly more fuel than the OEM units, making them well-suited for high-power builds including forced induction applications. Each rail provides three 8AN ORB ports and a 1/8" NPT port, offering ample connection points for pressure regulators, pulse dampers, gauges, or other fuel system accessories.

The unique profile was engineered to maintain maximum distributor clearance while keeping all fuel injectors in an exact perpendicular orientation - just like OEM - with no spacers needed. As an upgrade rail, OEM or OEM-equivalent injectors must be retained. For a complete bolt-in fuel system solution, the optional 20-1302-PK plumbing kit (sold separately) includes a multi-port regulator, pressure gauge, EFI hose, PushLok fittings, and spring lock adapters to connect directly to the factory fuel feed lines.
