To ensure accurate readings, pump head maintenance should be performed every six
months, or sooner, depending on usage. One pump head maintenance kit
(P/N 79190003) has been included with your pump purchase. Disregard the foam
insert included in the kit.
The pump has two pump heads. Use the following instructions to clean and maintain
each pump head.
Note: Dynojet recommends cleaning one pump head at a time.
1 Remove the sensor.
2 Remove the four No. 2 phillips head screws securing the pump head service cover
and remove the cover.
