Fuel Pump: Included – This tank has a special pocket with a flange that will only accept the GM in-tank pump assembly. Fat Fender Garage uses this pump in every Coyote swap build in our shop. It is the same pump used in millions of vehicles and has years of research and development behind it. Plus, you can pick up a replacement pump at most auto parts stores.

Fuel management system: Included. Fat Fender Garage uses a PWM fuel management system in every one of our Coyote swaps. It allows us to run a returnless fuel system, just like Ford designed. Using the PWM system with the GM fuel pump provides you with a clean installation that provides reliable performance and only requires a single fuel line running to the fuel rail. No need for external fuel regulators or gauges on the firewall with this setup so you can keep your engine bay clean and tidy. An additional benefit to the PWM system is it prevents pump overheating by controlling pressure by voltage vs running the pump at 100% duty cycle and choking it down with a fuel regulator.

  • The PWM Coyote fuel module control system has everything needed to provide a true OE-type returnless fuel system for the Ford Coyote engines. When used with the GM fuel pump, the system will provide the fuel volume and manifold referenced fuel pressure as specified by Ford. The key to making this system simple to use is the stand-alone manifold pressure sensor that tells the PWM controller how to adjust the fuel pressure to the Ford specifications.

Fuel Level Sensor: Included – We include a 0-90 OHM fuel level sensor with our Coyote Swap tanks. If you need another OHM range, please tell us in the notes section at check out.

Rollover Safety Vent: Included – The rollover safety vent is a simple ball check valve that allows air in and out of the tank as needed. In the event of a rollover, the ball will drop and block the vent port from leaking fuel. Additionally, it also has a small float inside that will help reduce the amount of liquid entering the vent hose from fuel slosh during normal everyday use.


Running more than 550 HP? Upgrade to the 800 HP GM fuel pump for higher power up to 800 HP. It has two 190 lph at 58 psi/400 kPa fuel pumps in OE type primary fuel pump module. The module flows (with jet pump to fill module and jet pump for fuel transfer functioning) 270 lph at 13.5 vdc/58 psi and 335 lph at 14.8 vdc/58 psi. *This is a special order item – please contact us for current pricing and availability. This 800 HP pump also requires the PWM  fuel management system.
