Fuel Line Fittings
1. Leave the Pulsation Damper’s base clamped in the vise.
2. Determine which fuel line fitting type is most appropriate
for your application, (please refer to steps 8-12 on pages 7
and 8 in the Mechanical Installation section of this
document). Any type of fitting, (straight, 45°, or 90°
elbow) is acceptable on the Return Sensor’s outlet port.
3. Coat the fuel line fitting’s ¼” MNPT threads with sealant.
4. Tighten hand tight.
5. Place an adjustable wrench on the Sensors body to act as a
counter torque.
6. Use an adjustable wrench to tighten the fuel line fitting into
the Sensors outlet port.
7. Straight, and 45° elbow fittings are each acceptable at the
Return Pulsation Dampers inlet port
8. The return Pulsation Damper’s inlet port has ½” FMPT
threads. If a 90° elbow fitting is required, use a ½” elbow
with ½” MNPT threads.
9. If the pulsation damper base is clamped in the vise, a
counter torque wrench is not required for installing the inlet
fitting.
• CAUTION: When tightening the fuel line fitting into Return Sensor, always place a counter torque wrench on the Return
Sensor’s Body.
• Never put a wrench on the Return Sensors Hex Flow Straightener while assembling the fuel line fitting into Return Sensor.
If the Return Sensor is held at the Hex Flow Straightener it may be moved. 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 its 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.
