1. Clamp the Pulsation Damper’s aluminum base in a vise.
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 Outward Pointing
Arrow, (Í).
4. Tighten hand tight.
5. Coat the Hex Reducer Nipple’s ¼” MNPT threads with
sealant.
6. Place the Return Sensor’s Hex Flow Straightener onto the ¼”
MNPT Hex Reducer Nipple threads.
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’s Hex
Straightener onto the Hex Reducer Nipple’s ¼” MNPT
threads. DO NOT put a wrench on the Return Sensor’s
body.
10. When tightened, the Return Sensor’s body and the Pulsation
Damper base must be even.
• CAUTION: When tightening the Return Sensor onto the Hex Reducer Nipple, always place the wrench on the Sensor’s Hex
Flow Straighterer.
• Never place a wrench on the Return Sensors body while assembling the Sensor onto the Return Pulsation Damper. If the
Return Sensor is tightened at its body, the Sensors Hex Flow Straightener may be moved. 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.

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.
