JMS Chip FuelMAX Fuel Pressure Switches

Not Yet Reviewed

JMS Chip FuelMAX fuel pressure switches are part of a high performance digital voltage booster designed to increase the output of an existing electric fuel pump by up to 85 percent. FuelMAX boosters allow the stock fuel system to support higher horsepower levels (up to 1,000 hp or more, depending on the setup) without needing to install an entirely new, more expensive fuel pump. Adjustable fuel pressure activation switches are available from 3 to 7 psi, and from 15 to 20 psi.
