2. Coat the fuel line fitting’s ¼” MNPT threads with sealant.
3. Place the fitting into the Sensor’s Hex Flow Straightener.
4. Tighten hand tight.
5. Place an adjustable wrench on the Sensor’s Hex Flow
Straightener to act as a counter torque.
6. Use an adjustable wrench to tighten the fuel line fitting into
the Hex Flow Straightener.
7. Whenever possible, use a straight fitting on the Forward
Sensor’s inlet port. If required a 45° elbow fitting can be
used.
8. 90° elbow fittings on the Forward Sensor’s inlet port should
be avoided.
9. Determine which type of fitting is required for the Pulsation
Damper’s outlet port.
10. If the Pulsation Damper’s base is clamped in a vise, a
counter torque wrench is not required for the outlet fitting
assembly.
11. Straight, 45° or single 90° elbow fittings are each
acceptable at the forward Pulsation Damper’s outlet port.
12. The Pulsation Damper’s outlet port has ½” FMPT threads.
If a 90° elbow fitting is required, use a ½” elbow with ½”
MNPT threads.
• CAUTION: When tightening the forward fuel line fitting into the Forward Sensor’s Hex Flow Straightener, always place a
counter torque wrench on the Sensor’s Hex Flow Straightener.
• Never place a wrench on the Forward Sensor’s body while assembling the fuel line fitting into the Forward Sensor’s Hex
Flow Straightener. The Hex Flow Straightener is locked into place with a very strong retaining compound. It must remain in
position and must not be tightened or loosened. Moving the Hex Flow Straightener in relation to the Sensor body will
destroy the Sensors accuracy. Turned Hex 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.
