Abstract
An in-line pump construction for mounting in a fuel tank or fuel line having line connections at each end of a tubular construction, valves mounted within the tube and a filter retained by a line connector nipple at the inlet end adjacent a valve module, there being a remote control module positionable at a distance from the pump for easy access and replacement.

A fuel pump adapted for mounting in a fuel line which comprises:
- a. a tube forming a body,
- b. a solenoid coil assembly mounted concentrically around one end of said body,
- c. a tubular armature slidable in said body in the area surrounded by said coil, said armature having a stepped bore, one end of said stepped bore serving as a guide for a flow check valve, the other end of said bore serving as a valve seat retainer,
- d. a cup-shaped valve seat having a valve opening in the bottom thereof and positioned in said other end of said stepped bore,
- e. a slidable flow check valve member guide in said bore having a valve portion to cooperate with said valve opening in said valve seat,
- f. a second valve housing at the other of said body having a valve seat and valve recess,
- g. a valve in said valve recess to cooperate with said seat,
- h. spring means interposed between said cup-shaped valve seat and said second valve housing to serve as a retainer for said cup-shaped valve seat and a resilient bias for said armature, and
- i. means to retain said second valve housing in said body against said spring means.
