JMS Electric Fuel Pump

JMS FuelMAX: Smarter Electric Fuel Pump Performance

When it comes to getting more out of your electric fuel pump without tearing apart your fuel system, JMS has engineered a solution that stands apart from the crowd. Rather than simply replacing a factory pump, JMS takes a fundamentally different approach — electronically boosting the voltage that drives it. The result is their flagship FuelMAX line of fuel pump voltage boosters, a product category where JMS has carved out a well-earned reputation among performance enthusiasts.

The FuelMAX Technology Explained

Electric fuel pump performance is directly tied to operating voltage. JMS recognized this and built the FuelMAX platform around exclusive digital technology to exploit it. FuelMAX Fuel Pump Voltage Booster features exclusive digital technology that provides up to an 85% increase in fuel delivery from your factory OEM fuel pump, delivering the highest continuous voltage and amperage output without the noise.

FuelMAX V2 boosts and regulates voltage on all vehicles, ranging from 14.4 volts to a maximum output of 22 volts, and supports up to 1000 horsepower with a single pump and 1350 horsepower with the stock dual pumps. That kind of headroom makes the FuelMAX a go-to upgrade for high-performance builds on Mustang Shelby GT500s, Dodge Challengers, Hellcats, Chevy Camaros, Corvettes, RAM 1500 TRXs, and even Nissan GT-Rs — all without swapping out the stock pump.

Plug-and-Play Installation & Smart Activation

One of the most practical aspects of the JMS FuelMAX is how straightforward it is to install. FuelMAX splices into your existing fuel pump's +12V DC feed wire , meaning there's no need for a new fuel pump, new sending unit, or complex plumbing changes. It is compatible with all 12V or 16V battery systems and works on all domestic and import vehicles and race cars with factory in-tank or external electric fuel pumps.

JMS also engineered smart activation into the FuelMAX. The adjustable voltage ramp-in and ramp-out allows you to choose a time ramp or from a monitored 0-5V sensor , so the boost kicks in precisely when your engine demands it — not continuously. The system also eliminates fuel pressure spikes, and a green status LED lets you know at a glance what the unit is doing, with a blinking LED indicating active voltage boosting.

OEM-Grade Engineering Pedigree

For more than 34 years, the JMS Daytona Group has been developing and manufacturing electronics for OE, Tier 1, and aftermarket customers. Their products and designs are known for reliability, regulatory compliance, and real-world performance, with past and current customers including Ford, Roush, TI Automotive, TI Fluid Systems, Edelbrock, DynoJet, and Harley-Davidson. That OEM-level engineering discipline translates directly into the FuelMAX — FuelMAX V2 is proudly designed and assembled in the U.S.A.

JMS also backs their electric fuel pump products with a strong warranty: JMS warrants to the original purchaser that their product will be free from defects in materials and workmanship for a period of three years from the original purchase date.

Whether you're building a street-driven supercharged muscle car or a dedicated track machine demanding consistent fuel delivery at high horsepower levels, JMS FuelMAX voltage boosters offer a technically sound, installation-friendly path to maximizing what your electric fuel pump can do.
