SX Performance™ Series of Fuel Pumps are designed exclusively for high-horsepower fuel-injected and carbureted engines.
SX high pressure fuel pumps are designed to move a higher volume of fuel at a much greater velocity than our competitors' pumps. Now you can have the volume of fuel you need, where it's needed, when it's needed.
Make no mistake about it, SX Performance™ has perfected fuel pumps that handle both high-pressure/high-volume and low-pressure/high volume fuel systems in even the most demanding high HP applications!
So, no matter what you're running, our pumps let you switch between carbureted and fuel-injected systems simply by changing the regulator.
Pumps are available in red, blue, black, and purple Mil-Spec Anodize.
