Mustang 4.6 3V Fuel Hat
The 4.6L 3V motor in the Mustang GTs is a legendary motor. A massive following with amazing aftermarket support – there are virtually no limits to what has been done to this powertrain. With any need to make power – a steady supply of fuel is needed. Enter the TopHat™ fuel solution designed and manufactured by Custom Performance Engineering, Inc. The Mustang 4.6 3V Fuel Hat fits up to 3 fuel pumps. Typically we see customers use AEM pumps, Walbro 255’s, Walbro 400’s, or Walbro 430 series pumps.
The TopHat™ is the ultimate solution for all fueling needs, designed to take up to three 465Lph pumps. The design was also intended to be plug and play, easy to install and reliable with many features to make the transition easier and have you on your way to meeting your power goals.
The TopHat™ Mustang 4.6 3V Fuel Hat, engineered and manufactured by Custom Performance Engineering, Inc., is the ultimate in upgrades for the fueling system. Accommodating those wanting to run two pumps for a bump in power, to those targeting 1200hp with ethanol – this setup is the all in one solution.
Any fuel coming back through the return line is fed down through a ½” stainless steel tube to the bottom of the tank. This helps eliminate aeration of the fuel, providing a more consistent pickup. To further reduce aeration a side port has been incorporated, channeling fuel away from the pump pickup. The supplied O-ring plug blocks off one direction or the other.

Supports Up to 3 Pumps
The design of the fuel system supports up to three 400lph fuel pumps, delivering more fuel than the more standard 255lph pumps. The pumps are secured with O-rings for optimal height and to isolate vibrations from the aluminum body of the system.
To cut the cost of upgrading, simplify the amount of parts and eliminate additional plumbing to reduce leaks we have integrated the merge for the three fuel pumps in the hat itself. Ease of installation is always a big concern for our customers and cp-e™ is striving to deliver in this department.
OEM Fit and Finish
Reverse engineering using a CMM arm, modeling OE components and with precision CNC manufacturing we are able to make the TopHat™ as plug and play as possible. We utilize the factory siphon system to extract fuel from the other side of the fuel tank. Necessary features have been CNC milled to mimic OEM design to accommodate the factory level sender, placing it in the exactly the same position as OEM.
The wiring harness is isolated and sealed from the fuel tank with a proprietary Delrin wire seal. Delrin has one of the highest resistances to fuels of any plastic, so it was chosen to provide a lifetime of trouble free operation.
