Description
Radium 3/8in SAE Male to 1/8NPT Male - Ford Mustang GT FN 18-21
Application: 2018+ Ford Mustang GT 5.0L Coyote (direct injection) with Radium 20-1433 fuel rails
Part Type: 3/8" SAE quick connect male to 1/8" NPT male adaptor
Part Number: 14-0358
When fitting Radium 20-1433 fuel rails to the direct-injected Ford Coyote, this adaptor is required to connect the OEM direct injection pump feed hose – unless the Radium 20-1433-PK plumbing kit is purchased, which includes its own feed adaptor.
It converts a 3/8" SAE quick connect male to a 1/8" NPT male thread. As with all NPT fittings, the tapered threads seal through interference and need a small amount of PTFE paste or tape.
Key Features
- SAE Side: 3/8" SAE quick connect male
- NPT Side: 1/8" NPT male
- Purpose: Adapts the OEM direct injection pump feed hose to Radium 20-1433 fuel rails
Optional Parts
- Radium Fuel Rails, Ford Coyote / Voodoo (20-1433) – the Radium fuel rails this adaptor is required for
- Radium Fuel Rail Plumbing Kit, Ford Coyote / Voodoo (20-1433-PK) – includes a DI pump feed adaptor, so 14-0358 is not needed if you buy the kit
Important Notes
- Not required if the Radium 20-1433-PK plumbing kit is purchased
- NPT fittings seal through the interference of the tapered threads – apply a small amount of PTFE paste or tape to the NPT threads
