Claims2
A method of forming a reciprocating pump body having a fuel inlet feed duct, a cavity and a cam shaft housing comprising the steps of:
- a. continuously drawing a member having an outside configuration which is the outside configuration of the finished pump body;
- b. said member having three longitudinal cavities therein, a first of said cavities being adapted to serve as a fuel inlet feed duct, the second of said cavities being adapted to serve as a cavity, and the third of said cavities being adapted to serve as a cam shaft housing;
- c. said first, second and third cavities extending longitudinally completely through said body;
- and
- d. cutting said body to the length required to form a pump body, said cutting being performed normal to the axis of said three longitudinal cavities.
