Incorrect use/choice of fuel pump

Wrong pump

Time and again, an incorrect fuel pump for the intended purpose or electronic equipment is selected from catalogues during replacement or for retrofitting.

This then delivers too high or too low pressure.

Improper use

A more serious case is when a fuel pump is used in a manner for which it is not intended.

Fuel pumps are designed to convey fuel (petrol, diesel).

For most people, this goes without saying. Nevertheless, complaints are occasionally received concerning fuel pumps that have been used to convey other fluids (water, oil, battery acid).

Rubber sleeve

This rubber sleeve compensates for the larger sizes of competitors’ pumps, in order that fuel pumps sold by Motorservice can fit in existing mountings. In addition, the rubber sleeve has the advantage of preventing vibrations from being transmitted to the body.
