Competition Kit Perfect for the do-it-yourselfer who wants to do it right. This system is great for naturally aspirated applications making 400 to 1000 HP at pressures up to 45 PSI and 400 to 700 HP for forced air or nitrous applications. This system consists of the back half kit plus Aeromotives 5.0 Street Rail Kit, A1000 Injected Bypass Regulator, a “Y” block to feed both fuel rails, and braided feed and return lines. It’s basic physics Electric fuel pumps act via "positive displacement." Put gasoline in a negative pressure environment as you do with after-market pickups, and you lower the boiling point of the fuel. The result? Cavitation, vapor lock, and restricted lubrication. With its baffled sump, the Aeromotive 5.0 Sumped Tank ensures a head of fuel at the pump inlet. So even at start-up, you can forget about cavitation or vapor lock, and your pump receives a constant flow of lubricant. Aeromotive Believes In Testing! Before Aeromotive date-code a fully assembled fuel pump, they test every production pump for flow at pressure and current draw. Finally, they package it for shipment. For example: the A1000 Fuel Pump ran 1,000 hours continuously at 45 PSI. Then, technicians installed the test pump on Aeromotive's company drag car for some "real world" testing. Then - and only then - was it qualified as an Aeromotive-worthy design.
