Installing (UYpgrading) An Aeromotive Dual Phantom 340 In-Tank Fuel Pump Module In A Muscle Car

Jefferson is back at it, installing a new Aeromotive Dual Phantom system on his Buick GS. The car already has a single Phantom in it, but it needs the dual setup because he’s upgraded the engine combo with a ProCharger and plans on more power down the road as well. Check it out.

Video Description:

Our 1971 Buick GS had been Gen V LT1 swapped a long time ago, using an @chevroletperformance LT1 Connect and Cruise system. We used an @AeromotiveFuelSystem Phantom PWM fuel control module. This was fine for the stock engine, but we have since added a @ProChargerSuperchargers D1SC blower, pushing the power from 460 hp up to about 700ish, which is the published limit of the pump. We have plans on a cam change and tuning to push the engine to the 850ish range, so we decided to upgrade the pump from the single to the new dual phantom system, which is capable of handling 2000hp (Carb NA) and 1400 hp in boosted EFI applications like our GS.

Jefferson takes you through the entire process of setting up the new dual-pump module, and installs it into the tank along with a few tricks he has learned from installing a few of these modules in different tanks.

This pump module works for all styles of engines, carb, EFI, and boosted versions. You can even run one pump for the main fuel system and the second pump for secondary fuel such as pump #1 feeding the Direct-Inection system and #2 feeding a set of injectors in the intake. For Gen V engines, this is a popular route, as the stock injectors are only good to about 750hp and are very expensive to upgrade. You can install a set of injectors in the intake and the second pump can feed them independently of the high-pressure system.

The Phantom fuel pump modules are capable of return-style for static pressure or PWM control.
