Radium Specialty Adapters | Flex Fuel Sensor / K-Series Press-Fit / Check Valve (20-0589 / 20-0909 / 20-0598 / 14-0058-01)

Four specialist adapters that each solve a problem no generic fitting will.

A group of Radium Engineering specialty adapters: a flex fuel sensor adapter, a Honda K-Series valve cover press-fit, a pump outlet check valve, and a large barbed hose adapter with an NPT port.

Choose Your Part

• Split-flow flex fuel sensor adapter (20-0589): plumbs a flex fuel sensor into the system
• 10AN male press-fit, Honda K-Series (20-0909): presses into the K-Series valve cover, no threading
• Pump outlet adapter check valve, 6AN male (20-0598): adds check valve function at the pump outlet
• Hose adapter for 1.1in hose with 1/4in NPT port (14-0058-01)

Features

• Anodized aluminum construction
• Press-fit design on the Honda K-Series adapter, no valve cover threading required
• Integrated check valve on the pump outlet adapter
• 1/4in NPT port on the 1.1in hose adapter for a sensor or gauge

The Details

The 20-0598 check valve adapter matters on pumps that lack one integrated. Several popular pumps ship without a check valve, and on a return style system that means pressure bleeds down after shutdown; this restores it at the pump outlet.

The 20-0909 press-fit is the Honda K-Series equivalent of the Nissan valve cover fittings: it presses into the cover rather than threading, which is how those covers are designed to accept a vent fitting.

The 20-0589 split-flow adapter gives a flex fuel sensor a home in the fuel system without building a custom bracket and line arrangement around it.

Applications

• 20-0909: Honda K-Series valve covers
• 20-0589, 20-0598, 14-0058-01: universal

Important Notes

• Confirm your pump does not already have an integrated check valve before adding the 20-0598
