The DeatschWerks X3 Series module replaces the complete in-tank fuel pump assembly with a billet aluminum module carrying three DW400 pumps rated at 415 lph each. Tested together at 13.5 V and 58 psi, the three pumps flow 935 lph (4.1 gpm) and support 1700+ whp on pump gas with forced induction. The module retains the OEM fuel level sensor, tank capacity, venturi and surge features, runs return style plumbing with a -10AN ORB feed and -8AN ORB return, and is ethanol compatible. DeatschWerks strongly recommends its FPHWK hardwire kit, and the factory fuel pump control module may need its variable duty cycle disabled or bypassed.
