New Vortech 255LPH Inline Fuel Pump Kit for 86-93 Mustang 5.0 with Forced Induction. Comes with eveything needed to install, including instructions. As fuel pressure requirements increase, fuel flow drops. This is particularly important with Vortech superchargers, as they raise fuel pressure in proportion to boost to deliver a correct air/fuel ratio under boost. That's why Vortech created the T-Rex series fuel pumps. They're specially designed to maintain a high flow rate at elevated pressures and to keep your boosted engine supplied with enough fuel to make serious horsepower. Complete kit including wires, relay, hoses, fittings, and a template.
