Modern petrol pumps build pressures of up to 500bar these days. This is necessary to get high power from relatively small engines combined with the lowest possible emissions. High demands are therefore placed on the construction of these fuel pumps.
To ensure proper operation of the petrol HP pump, it is very important to carefully follow the manufacturer’s installation instructions. Clean operation is an absolute necessity in this respect. Naturally, any cause of pump failure must be eliminated prior to installation.
