The fuel pump is one of the most important parts of the engine, as it allows the right fuel supply. It is made of two different parts: the hydraulic part, which is the real pump made of aspiration and exhaust valves, and the pneumatic part. Between these two parts, we have an elastic membrane working as a pumping element, as well as a separator. Thanks to the oscillation of the membrane, the volume in the pump housing changes and fuel flows from the tank to the carburetor.

ATECSO develops both single pumps and complete modules for both aftermarket and OES.
