Fuel Systems

Give your fuel tank the fluids it needs with our range of fuel systems additives and accessories. The Sinister Fuel Tank sump kit is designed to feed the biggest aftermarket lift pumps. If your truck requires added fuel flow or your factory draw straw is picking up fuel when the tank is getting low, a Fuel Tank Sump kit is an ideal, affordable solution. We also carry a full range of Airdog fuel systems products, including fuel air separation systems, fuel filters, water separators, and more.

FASS fuel systems provides a selection of superior pumps, pressure regulators, water separators, fuel filters, and more. With strength and reliability even in the most extreme conditions, FASS fuel systems are designed to fit in any truck. For a high performance pump with an adjustable regulator, Raptor’s 6.4L pumps deliver excellence every time. Order your FASS, Raptor, and Airdog fuel systems today from MKMCustoms.com.
