GT500 Fuel Flow
July 02, 2013
I ordered the Ford Racing dual fuel pump to pair with my TVS-2300 RoushCharger, also purchased from American Muscle. Both were installed together on my 2007 GT. Though Roush told me the dual pump wasn't absolutely necessary for the blower install, I plan on further upgrades and wanted the extra insurance the GT500 pump provided.
Installation was easier than expected, though still not quite a breeze. Do NOT plan on installing the pump yourself, as an extra set of hands is essential to hold the pump down in the tank while securing it with the lock ring.
Once the pump is in the tank, installation gets a LOT easier. Mount the driver for the second pump on existing studs in the spare tire well, ground it, plug in the harnesses to the drivers and the pump itself, and run a power wire to the front fuse box. If you can install a stereo system in a car, you can wire this fuel pump.
I had a minor problem wiring the fuel sender, as it requires removing wires from the stock sending unit harness and adding it to the one included with the pump. I could not get the stock wires to seat well in the new harness. On startup I received a "DTE FLI DATA ERROR" which caused a check engine light, no fuel level to register on the gauge, and the car to run rough. Eliminating the harnesses and wiring the fuel sender directly fixed the issue. If you get this error and attempt to fix it by re-wiring, please note that it will take about 30 seconds after starting for the sender to clear the error.
Though it's still very early, I'm very pleased with the Ford Racing dual fuel pump. It provides so much pressure, my Mustang starts almost instantly after turning the key. I now have the peace of mind to upgrade whatever I want without having to worry about the fuel supply. Plus, it's an OEM-quality Ford piece, and it's fairly easy to install. To top it off, even with this high-flow pump and the new supercharger, I'm still averaging 25-27 mpg on the highway.
If you plan on installing a forced induction system, this fuel pump is an essential upgrade. While many may balk at the price, the quality of this piece makes it worth the money. Besides, it's still MUCH cheaper than scattering engine internals across the road because your stock or bargain fuel pump caused a lean condition.
