1987 Buick Grand National Fuel Pump

The quietest method for providing juice to a 10-second V-6 is a double-pumper in-tank fuel pump setup, which Cotton's sells. This Quad Air XP Plus double-pumper is comprised of two Walbro 340 pumps that flow 255 L/hr. One runs all the time, and the other kicks on when the boost comes up. Since it's already pre-wired, it makes for a near-factory installation and none of the visual or audible changes of going to an external fuel system.
