Fuel Rate

Use fuel measuring device, Part No. 3376375, to mea-

sure the rate of fuel consumption.

Install the fuel measuring device as follows:

• The fuel return hose from the engine to the fuel

measuring device (A).

• The fuel inlet hose to the fuel filter inlet (B).

• The return hose from the device (C) to the fuel tank.

• The fuel inlet hose to the device from the fuel tank

suction line (D).

NOTE: Adjust the fuel rate to compensate for temperature

variation if required.

Fuel Inlet Restriction

Measure the fuel inlet restriction. Install a vacuum gauge,

Part No. ST-434, between the fuel pump inlet and the

gear pump inlet.

NOTE: Do not measure fuel inlet restriction with the fuel

measuring device installed. This will not measure the inlet

restriction of the vehicle’s supply plumbing.

Hold the gauge at the same level as the gear pump.

NOTE: The gauge will not measure the correct vacuum if

the gauge is not held at the same level as the gear pump.

Operate the engine at maximum horsepower RPM and

Advertised Horsepower.

Observe the reading on the gauge.

NOTE: The maximum fuel inlet restriction is as follows:

STC CELECT™

(plus ECM Cooling Plate)

Clean fuel filter: 102 mm Hg

[4 in Hg]

127 mm Hg

[5 in Hg]

Dirty fuel filter: 203 mm Hg

[8 in Hg]

228 mm Hg

[9 in Hg]

Correct the restriction or replace the fuel filter.
