Walbro F50000112 5CA400 In-Tank Fuel Injection Pump (AOF216) Mercury Marine 880596T58 Low Pressure Mercury Marine

The Walbro F50000112 fuel pump is the perfect mild upgrade pump for EFI fox bodies making under 450rwhp. From heads/ cam 302 to 347, 408s, and even as a replacement pump in bone stock or near stock applications, the 112 is the ideal pump for unmodified or mildly modified naturally aspirated applications. It requires no wiring changes whatsoever, will not overload the factory wiring, and will not overpower the factory fuel pressure regulator.

The F50000112 pump is dimensionally identical to an OEM Mustang 5.0 EFI pump, except it flows more.
