On some systems, a portion of the fuel is used for lubrication and cooling. This fuel bypasses the nozzle tip and returns to the fuel tank.Let''s take a quick look at the individual components that make up the fuel system.* Fuel drillpressmanufacturers Tanks -- All fuel tanks have a fuel intake fitting on top of the tank for filling and a drain or outlet fitting on the bottom. drillpressmanufacturers One or two additional fuel fittings may be found for returning unburned fuel to the tank.Fuel tanks are not trouble-free components. Metal tanks will eventually rust. The rust, combined with water from condensation, forms a mud inside the tank. Sludge forms in the tank when unburned carbon from injector nozzles is carried back to the tank with overflow fuel and combines with water. Thin flakes of hardened mud or sludge can easily plug the fuel outlet hole. This usually occurs when the tank is severely shaken.
