Force Fuel sump kits use your stock low-pressure manual or EFI pump to feed their sump tank. The pump is submerged in fuel for cooler and quieter running, and delivers 58 psi of high-pressure fuel to the throttle body at a rate of up to 340 lph (89 gph). For excellent performance and overall ease of operation, buy FiTech Ultimate LS EFI 500 HP fuel injection systems with Force Fuel sump system. Additional Force Fuel sump system features: * Low fuel level in the fuel tank will not result in pump starvation when vehicle is on a steep incline * Generally mounted in the engine compartment, but can be attached to the vehicle's chassis. * Supplied high-pressure hose includes 5 ft. of high-quality EFI -06 fuel line and fittings for plumbing from the Fuel Command Center 2.0 to the EFI throttle body Additional Ultimate LS features: * Optional GM transmission control feature is suitable for 4L60, 4L65, 4L70, or 4L80 * Black anodized aluminum parts for style and corrosion resistance * High-flow, cable-operated throttle body * Bosch wideband-controlled * Stainless oxygen sensor bung * Compatible with car and truck coils * AN fittings and fuel crossover * Works with custom cams * Designed for applications making at least 6 inches of vacuum at idle * 24X and 58X crank and cam compatible * Programmable touch screen hand-held controller with data log features * Suction cup mounting bracket
