Mallory's new fuel pump for high pressure fuel injection is now available in an in-line configuration. It is compact in design so it's great when space is tight. This is a high pressure high volume 12-volt pump. This muscular pump delivers 110+GPH free flow at 14 volts. At 40psi and 14 volts it pumps 83+GPH and 73+GPH at 65psi and 14 volts. Use Mallory regulator 4305M for best performance. It's also best to use Mallory's pre-filter 3175 to protect the pump.
