Radium Fuel Rails and Plumbing Kit | Ford 302 / 351 Windsor (20-1302-PK / 20-1302 / 17-0064)

A 5.0 build outgrows its factory fuel rails long before it outgrows anything else, and the OEM spring lock plumbing is the next thing to go.

The Radium Engineering fuel rails for the Ford 302 and 351 Windsor replace the factory rails with CNC machined billet running large 5/8in internal bores, so flow stops being the limit. Ports are tapped 8AN ORB and 1/8 NPT, which opens up a regulator, gauge, or pulse damper wherever the manifold allows. The matching plumbing kit takes it the rest of the way.

Choose Your Parts

• Fuel rails (20-1302): the billet rail set. All fittings sold separately.
• Fuel rail plumbing kit (20-1302-PK): replaces everything downstream of the OEM spring lock lines, including an MPR-RA multiport regulator and gauge
• Bosch EV1 injector connector adapter (17-0064): for injector connectors that foul the lower intake manifold. Sold individually.

What You'll Feel

• Fuel flow that keeps up as injectors and power grow, through 5/8in bores
• Even distribution across both rails, run in parallel off a dead head regulator
• Fuel pressure you can calibrate and monitor rather than guess at
• E85 compatible hose throughout, not just gasoline-rated line

Features

• CNC machined billet fuel rails with large 5/8in internal bores
• 8AN ORB and 1/8 NPT tapped ports
• Plumbing kit with MPR-RA high flow dead head multiport regulator
• 1:1 fuel pressure regulator and gauge included in the plumbing kit
• PushLok hose ends with EFI hose, customisable to the vehicle
• EFI hose compatible with all fuel types including E85
• Plugs included for all unused ports

The Details

The plumbing kit is the interesting part. It replaces every OEM component downstream of the factory spring lock fuel lines and runs the two rails in parallel through a dead head MPR-RA multiport regulator, which is what delivers even distribution across all eight injectors rather than favouring whichever rail sees pressure first. The supplied 1:1 regulator and gauge make pressure a set-and-check item. Because it uses PushLok hose ends with EFI hose, the routing can be tailored to whatever chassis the engine is sitting in, which matters given how many different cars these engines end up in.

The EV1 adapter solves a specific problem rather than a general one: on some injector and manifold combinations the connector interferes with the lower intake, and this adapter relieves that. Order one per affected injector.

Kit Includes

• 20-1302: billet aluminum fuel rails with mounting hardware. Fittings sold separately.
• 20-1302-PK: MPR-RA multiport regulator, 1:1 fuel pressure regulator and gauge, EFI hose, PushLok hose ends, adapter fittings, and plugs for unused ports
• 17-0064: one Bosch EV1 injector connector adapter
• NOT included: fuel injectors

Important Notes

• No fittings are supplied with the rails; select ORB fittings to suit your plumbing
• Leave clearance around any port carrying a regulator, gauge, or pulse damper
• The plumbing kit is designed for use with the Radium 20-1302 rails
• The EV1 adapter is sold individually; order the quantity your build requires
