SX 18203 EFI + Carbureted Fuel Pump
SX 18203 EFI + Carbureted Fuel Pump

Details 

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.

- The SX 18203 is a slightly more powerful pump than the Aeromotive A1000 pump and is completely E85 Compliant!

- Ultra high-flow rates exceed: 80 GPH at 12 volts and 45 PSI, AND 120 GPH at 12 volts and 10 PSI
- Flow-thru design maintains maximum cooling, produces outstanding reliability, and provides consistent fuel delivery from idle to full throttle
- -10 AN inlet/outlet fittings for easy installation

SX 41002 Fuel Filter
SX 41002 Fuel Filter

Details 

The SX Performance™ In-Line Fuel Filter is an ultra-high flow, advanced filter designed for engines demanding up to 2000 HP. The in-line design allows for a wide choice of mounting locations, ensuring hassle-free installation.
Our fuel filters are designed to maintain a fuel flow capacity that even exceeds the maximum output of SX Performance™ Model No. 18203 Electric Fuel Pump. Why? Because a restrictive filter design will starve fuel and rob vital performance from your pump, and even lead to premature pump failure! Now you can have absolute minimal pressure drop with maximum filtering flow.

-10 AN Inlet/Outlet Ports
- Comes with 10 Micron Filter Element
- Calibrated for all EFI and carbureted engines up to 2000 HP
- Compact flow-thru filter design and enlarged ports will literally flow the maximum of whatever a -10 AN line can handle
- Virtually no pressure drop [less than .15 PSI pressure drop at 200 GPH]
- Easily connects before and/or after the SX Performance™ In-Line Electric Fuel Pumps
- Quickly and easily install and remove aerospace fuel filter element
- Compatible with gasoline and methanol
- Mounting bracket included
- Avilable in red, blue, black, and purple Mil-Spec Anodize
