This is the MagnaFuel pump we're using in a home-brewed 572. This pump can support an EFI or carbureted engine that produces 1,500 HP. For the modified normally aspirated application (and most others), this pretty much exceeds the engine requirements. This pump can deliver anywhere from 20-120 PSI in use. When it was designed, MagnaFuel took other considerations into account. One of the most important was a steady fuel delivery curve from idle to full throttle. Another was quick response coupled with maximum cooling. Because of these design factors, reliability isn't a problem. The body of the pump is machined from 6061-T6 aircraft grade aluminum alloy. Internally, the pump uses a proprietary gear drive, flow-through configuration, allowing for big pressure capability, reliability and quiet operation in one package.
