LOW PUMP PRESSURE
The spool valve in the pump on the G4A-EL / 4EAT has been updated. (Figure 1) The purpose of the update was to create a seat for the spring. The old valve had no seat and sometimes the spring would snag in it's bore causing low line pressure.
The Ford part # is F02Z-7Z306-A. The Ford valve will work in the Mazda as well.
