MECHANICAL & WIRING OVERVIEW – Standard Flow (BOS, 201, 231, 235-2K)
To Ensure System Accuracy, Follow All Installation Instructions.
•
Sensor Placement. Determine where the Flow Sensor or Flow Sensor-Pulsation Damper assembly is to be installed. Install the
sensor or sensor-pulsation damper assembly so that the ports marked IN and OUT. All orientation arrows, (Ï) must be pointing
up. The forward sensor or forward sensor-pulsation damper assembly must be installed downstream of a Racor type primary
filter. Upon exiting the return sensor, fuel must travel “Up-Hill” on its way back to the fuel tank. The fuel return line, between the
return sensors’ outlet port and fuel tank should be no less than 12” and have a 1 to 2” upward rise. This keeps the return sensor
flooded improving accuracy. Place sensor assemblies in a protected location away from water spray.

Determine fitting type & size. Minimize the number of elbows and fittings. If swivel fittings are used, (JIC or SAE) their mating
surfaces must be sealed with FlareTite fitting seals. Fitting seals may be purchased through Fittings Inc. in Seattle, WA (206) 767-
4670, 1-800-552-0632, or a local hydraulic supply house.
