NOTES:
1) Make certain o-rings are in place on the bottom
of the gauge body.
2) Connect the low pressure transmission bolt (bolt
next to RED band on gauge) to the gauge port at
the filter outlet (down-stream side of filter).
3) Connect the high pressure transmission bolt (bolt
next to GREEN band on gauge) to the gauge port
at the filter inlet (upstream side of filter).
4) Torque bolts to 25 +/- 5 inch oz. A flathead
screwdriver with a 3/8” (1 cm) minimum blade
width can be used to assemble/disassemble the
gauge. Small blade widths will damage the bolt
heads.
