Overview
A high-horsepower fuel system plumbed with large AN lines is where this MagnaFuel pump belongs. It is an external electric unit with a filter and an aluminum body, mounted with an adjustable bracket.
Its pressure range suits carbureted setups, and the power rating is high for a single pump. The listing gives no flow rate and no wiring or fuse detail.
Who it's for
Racers and builders who run large AN fuel lines and need a filtered external pump. Street owners with a stock fuel system need a different part.
Pros and cons
- Large AN inlet and outlet
- Gas and alcohol rated
- Flow rate not listed
- Wiring requirements not given
- Universal fit means no application list
Performance notes
Fuel supply is set by the pump's pressure range and the line size, and the large AN ports limit restriction. Because it is mounted outside the tank, it should sit low and close to the supply for reliable priming.
