Launches fuel pump control units

MS Motorservice International GmbH has expanded its product range, the spare parts specialist now offering OE quality control units for fuel pumps. With 19 new applications, market coverage of approximately 10 million vehicles has been achieved, with plans already in place to expand the range.

Based on extensive market analysis, we have decided to meet the current requirements of our customers said Vice President of Product at Motorservice, Axel Laser. In addition to their extremely high quality, the control units impress with a number of environmentally friendly aspects.

The current applications are just the start, we will expand our product range in the coming months to achieve an even bigger market coverage,” states Laser, outlining the company’s plans.


In the case of an “unregulated” fuel supply, the fuel pump delivers fuel at full capacity at all times. As a result, excess fuel flows back into the fuel tank via the return line. With a “regulated” or “demand-based” fuel supply on the other hand, the fuel pump is triggered by the fuel pump control unit with a pulse width modulation signal (PWM signal).

Only the amount of fuel that is required is supplied – this is both more environmentally-friendly and more economical.

With the regulated fuel supply, the fuel is heated less and the risk of fuel vapour locks is reduced.

Another positive effect is noticeably lower noise due to a quiet-running fuel pump.


The Motorservice Group is the sales organisation for the global aftermarket activities of Rheinmetall Automotive (formerly KSPG).

It is a leading supplier of engine components for the independent vehicle component market with its brands Kolbenschmidt, Pierburg, BF and TRW Engine Components.

The comprehensive product range means that customers can obtain all engine components from one single source.

As a problem solver for dealers and repair shops, Motorservice offers an extensive service package and the technical expertise that you would expect from the subsidiary of a large automotive supplier
