Abstract
The main essentials of power units and their accessories have not changed significantly over the last 40 years, and fuel feed pumps come into this category. The basic requirements are well established, but there has been a continual striving for improved performance and strenuous efforts to reduce costs in order to meet the vehicle manufacturers' demands.
The author has endeavoured to indicate the trends in developments of the various types of fuel pumps, mechanical and electrical, with particular reference to application and performance for petrol and diesel equipment. The importance of correct installation is related to performance and reliability; design materials are discussed, particularly in relation to the influence of fuels and temperature and the need to meet the demands of modern high-output engines.
Mention is made of the relationship of fuel feed systems to safety and evaporative emission control and the special requirements of fuel injection installations. The need for efficient fuel filtration is discussed and the application and design details of filters are outlined.
