2. Coat the Hex Reducer Nipple’s ½” MNPT threads with
sealant.
3. Place the ½” MNPT Hex Reducer Nipple threads into the
Pulsation Damper’s base end with the Inward Pointing
Arrow (Î).
4. Tighten hand tight.
5. Coat the Hex Reducer Nipple’s ¼” MNPT threads with
sealant.
6. Place the Forward Sensor’s “OUT” port onto the ¼”MNPT
Hex Reducer Nipple end.
7. Tighten hand tight.
8. Use an adjustable wrench to tighten the Hex Reducer Nipple
into the Pulsation Damper base.
9. Use an adjustable wrench to tighten the sensor body onto the
Hex Reducer Nipple. DO NOT put a wrench on the Forward
Sensor’s Hex Flow Straightener, at the Sensor’s inlet port
10. When tightened, the Sensor’s base and the Pulsation Damper
base must be even.

• CAUTION: When tightening the Forward Sensor onto the Hex Reducer, always place the wrench onto the Sensor’s body.
• Never place a wrench on the Forward Sensor’s Hex Flow Straightener while assembling the Sensor onto the Forward
Pulsation Damper. The Flow Straightener is locked into place with a very strong retaining compound and must remain in
position. It must not be tightened or loosened. Moving the Flow Straightener in relation to the Sensor body will destroy the
Sensors accuracy. Turned Flow Straighteners are not considered warranty items.
CAUTION, DO NOT OVER TIGHTEN FLOW SENSOR FITTINGS. Over-tightening may crack the sensor’s body. Cracks
cause leaks, and fuel leaks sometimes cause catastrophic explosions and fire. Assemble fittings with a Lubricating, Fuel Proof,
Non or Semi Hardening pipe thread sealant, designed for aluminum and stainless steel threads, (Loctite 567 or equivalent).
DO NOT USE TEFLON TAPE.
