Collection: Fuel Systems - Fuel Pumps & Regulators

Fuel Pumps, Regulators & AN Plumbing

Browse fuel system components for carburetted and EFI builds, including pumps, pressure regulators, filters, gauges and plumbing accessories. Choose each component to suit your engine, fuel type and installation rather than relying on a single specification for the whole range.

Fuel Delivery Components

• Fuel pumps: Compare the individual pump's flow rating at your required operating pressure, fuel compatibility and mounting requirements.
• Fuel Pressure Regulators: Check the specified pressure range, port sizes and return or bypass requirements for your carburettor or EFI system.
• Fuel Filters: Select the element rating, connections and fuel compatibility recommended for your pump and engine.
• Fuel Pressure Gauges: Compare pressure ranges, gauge dimensions and thread sizes before ordering.
• Aluminium Fuel Line Hard Tube: Check tube dimensions, connection requirements and stated fuel compatibility for your installation.

Hose, Hose Ends & AN Fittings

Explore Speedflow hose and Speedflow fittings for your plumbing layout. Hose construction, pressure ratings and compatible fluids vary by series. Do not assume that every braided hose is PTFE-lined or suitable for every fuel.

Match hose ends to the specific hose series and size. Check adapter thread types, sealing requirements and fitting angles against your components before ordering. An AN size alone does not confirm that a hose end, adapter or port will suit your installation.

Before You Order

• Confirm whether your system is carburetted or EFI and identify its required operating pressure.
• Check each component's stated compatibility with your intended fuel, particularly E85, methanol or diesel.
• Confirm inlet, outlet and return connections, hose series and available mounting space.
• Follow the component manufacturer's installation instructions. Ask for application-specific advice if you are unsure.
