Looking to upgrade your fuel system? DIYAutoTune.com carries a wide variety of parts to keep up with the fuel needs of just about anything, whether it's an all motor compact or a drag monster with four figure horsepower numbers. The SX Performance parts that we carry may not be the most familiar name; they're American made products built by Essex Industries, who has a proven track record in building similar pumps and fluid systems for aircraft and military applications. Their pumps and regulators are built to the same standards they would use in military equipment. Our Delphi and SX Performance fuel system products are compatible with E85, so if you're using alcohol as cheap race gas, these can ensure you won't have corrosion issues.
