Key Features & Benefits – Universal External EFI Fuel Pump (044 style, 400 LPH), 12V – AN10 inlet / AN8 outlet
Universal External EFI Fuel Pump (044 style, 400 LPH), 12V – AN10 inlet / AN8 outlet is built for inline external installations where an EFI fuel system needs higher flow and steady fuel delivery under load.
The pump uses metric ports (M18×1.5 inlet, M12×1.5 outlet) and includes adapters for AN10 inlet and AN8 outlet plumbing, with a check-valve outlet fitting.
When is this useful?
Useful when upgrading an EFI fuel system for higher demand, provided your lines, filtration, regulator, and electrical supply are sized to match the required flow and pressure.

Selection & installation tips
- Match plumbing to the variant: AN10 inlet and AN8 outlet, with M18×1.5 / M12×1.5 pump threads.
- Follow the listed filtration: use a 100-micron pre-filter before the pump; EFI setups commonly add a finer post-filter based on system needs.
- Check polarity during wiring: markings indicate red as positive and blue as negative.
- Avoid unnecessary restrictions (tight fittings, sharp bends) to help maintain flow and reduce load on the pump.
- Verify voltage at the pump under load; low supply voltage can reduce real-world flow.
Before fitting, self-verify thread sizes, AN connections (AN10/AN8), filtration requirements, and your system pressure/electrical supply, then compare them to the specifications listed above.
