First decide where the check valve will sit in your fuel system.

• Inline check valve fittings: universal fittings that go into the fuel line itself.
• Pump outlet check valve adapters: fittings that thread straight onto the fuel pump outlet. The Radium Engineering 10AN ORB to Bosch 044 adapter is made for the Bosch 044 pump.
• Thread type and size: match the fitting's threads to your pump and lines, for example 10AN ORB. Check the size details on each product listing before you order.

Plan your fuel line layout before you order. Depending on your setup, you may also need matching hose ends, adapter fittings and hose to finish the connection. Follow the manufacturer's instructions for orientation and sealing. Installation by a professional is recommended.

What does a fuel check valve do?
It lets fuel flow in one direction only. This helps hold fuel pressure and stops fuel draining back when the pump is off.

What is the difference between an inline and a pump outlet check valve?
An inline check valve fits into the fuel line. A pump outlet check valve adapter threads straight onto the fuel pump outlet.
