50 THE SHOP MARCH 2021 utilize ethanol and methanol that have inherently high fuel demands." Related technological advancements, such as the increased use of smart gauges and data loggers that work as standalone units or with an OE ECU, allow racers to monitor and record fuel pressure at the track, says Lawson Mollica, director of marketing and public relations for AEM. "This technology is useful because a drop in fuel pressure, or an increase in injector duty cycle, can be indicative of starvation under high-G loads, a fuel filter clog or pos- sibly a failing pump," he explains. "While it is not directly related to fuel pump tech, it can certainly provide information on the status of the components of your fuel system." NEED TO KNOW Still, like other tech-oriented components, there are misconceptions to avoid—and, again, that can include not just fuel pumps, but the entire fuel system. "The biggest misconception surrounding fuel pumps for performance is that you can buy a fuel pump and then be done with it," Barrick advises. "We try to educate people to understand that it takes the whole fuel system to work correctly. It's about the filtration, fuel line sizing, regulator, and more. We understand that the fuel system isn't the sexiest piece of the performance puzzle, but it's something you don't want to worry about. By planning out the whole system, you'll never have to worry." Shops can increase fuel pump profits by stocking the newest part numbers and highlighting the latest applications on social media.
