Radium Engineering Pump Outlet Adapter - Check Valve with 10mm Barb

Radium Engineering Pump Outlet Adapter - Check Valve with 10mm Barb

Application: Selected in-tank fuel pumps (see fitment)
Part Type: Fuel pump outlet adapter with check valve
Part Number: 20-0798

The Radium pump outlet adapter integrates a high-flow check valve onto the outlet of many fuel pumps and converts it to a 10mm barbed connection. Two billet aluminium halves clamp around the pump outlet, held by a stainless steel retainer and bolts, while a stainless steel plunger and spring provide the one-way valve.

Compared with a standard integrated check valve (46–76 LPH flow restriction, 3.2–4.8A current draw), the Radium check valve restricts only 15 LPH and draws 0.5A. Less restriction lets the pump run at lower current, keeping fuel temperatures down and helping prevent cavitation. FKM O-rings seal the connection and provide E85 compatibility.

Key Features

• Low Restriction: Flow restriction of 15 LPH vs 46–76 LPH for a standard integrated check valve
• Lower Current Draw: 0.5A vs 3.2–4.8A
• Outlet: 10mm barb
• Construction: Anodised aluminium top and base with stainless steel plunger, spring and hardware
• E85 Compatible: FKM O-rings
