MARCH 2018 THE SHOP 45 The outside factor having the greatest effect on the fuel pump market is … … I would mention two factors: pump gas formulation and pulse width modulation (PWM). Since 1986 and the advent of OE in-tank fuel pumps, fuel engineers have given no consid- eration to what happens when you put fuel under a vacuum. The laws of physics tell us that when you put fuel under a vacuum, the boiling point drops. Combine that with how we build modern-day hot rods—low to the ground, large-diameter exhaust, higher under-hood and under-car tem- peratures, etc.—and it is easy to see why suction-side cavitation is an ever-present reality, due to fuel going to vapor at the inlet of an external fuel pump. The solution is an in-tank system such as the Aeromotive Phantom or a Stealth tank where you always have positive pressure at the inlet of the pump. Not all fuel pumps are compatible with systems that utilize PWM to control flow and pressure. The Aeromotive Stealth 340 features a turbine-style pumping mecha- nism, so it is compatible with PWM return-less systems, and is whisper-quiet. It is also an ideal fuel supply for the self- learning EFI units that have become very popular in the aftermarket. The Aeromotive Brushless Gear pumps are ideal for very high-horsepower applica- tions that utilize PWM as well. AEM PERFORMANCE ELECTRONICS Hawthorne, California Lawson Mollica Director of Marketing & Public Relations Our hottest fuel pump product for 2018 is … … our high-flow, E85-compatible, 400-lph Metric Fittings Fuel Pump. Its best features include … … what makes this pump really cool is that it has the same fittings as the popular 044 pump, so it will drop in as a direct replacement and deliver much more flow. We individually test every fuel pump to ensure that they flow at least 400 lph at 40 psi. It can sup- port around 860 hp at 30 psi of boost. We have a version with AN fittings as well, and offer male and female AN con- nectors, along with a pre-filter if someone wants to adapt this pump for in-tank use. The most common mistake shops make when working with customers on a new fuel pump purchase is … … one of the common issues we encounter is that the pre-filter is not installed or falls off and the pump is contaminated, causing a failure. Another issue is when the wiring to the pump is inadequate, rendering the pump unable to perform as intended, or even become dangerously hot. It is really important that the installer supply vehicle charging voltage, usually 13.5 volts, and it is available at the pump terminal, not the source of the power. One thing installers can do to make fuel pump installations faster and easier is … … to make sure you have any necessary ancillary components ready before you begin the installation. This could be any- thing from having the right adapters for an inline pump installation, to having the correct pre-filter and hardware when upgrading an in-tank fuel pump. The outside factor having the greatest effect on the fuel pump market is … … horsepower! We are so fortunate to be working at a time when today's produc- tion cars deliver performance capabilities that exceed many of yesterday's racecars. As these cars are converted to racecars, the Modern fuel pumps are designed to handle today's high- horsepower demands.
