Information:
Illustration 2 g02355128
Minimum TPIR flow rate for a 12 VDC system
Illustration 3 g02355130
Minimum TPIR flow rate for a 24 VDC system
Remove the temporary drain line from the drain port on the TPIR. Connect the TPIR return line to the TPIR.
If the fuel flow in Step 6 is greater than the minimum limit, proceed to "Low Compression (Cylinder Pressure)".
If the fuel flow in Step 6 is below the minimum limit, proceed to "Return Line Pressure Relief Valve Test".
If there is no fuel flow in Step 6, proceed to "Transfer Pump Inlet Regulator (TPIR) Return Test".Transfer Pump Inlet Regulator (TPIR) Return Test
In order to check the return flow from the TPIR, perform the following procedure:
Make sure that the TPIR return line is not blocked or kinked.
If the TPIR return line is clear, confirm that the Electric Fuel Lift Pump (EFLP) is operating. Make sure that fuel lines between the EFLP and the TPIR are not blocked or kinked.
If the fuel lines to the TPIR are clear and the EFLP is operating, replace the TPIR.
If the fault is still present, proceed to "Low Compression (Cylinder Pressure)".Return Line Pressure Relief Valve Test
In order to check the return line pressure relief valve in the secondary fuel filter base, perform the following procedure:
Make sure the keyswitch is in the OFF position.
Disconnect the return line banjo connection on the top of the secondary fuel filter.
Use a suitable blank to plug the return line.
Install a suitable drain line to the return line point on the top of the secondary fuel filter.
Place the open end of the drain line in a suitable calibrated container.
With the keyswitch in the ON position, measure the flow from the drain line.
If the flow from the drain line is less than 0.4 L (24.4 cubic inch) per minute, proceed to "EFLP Flow Test at the Primary Fuel Filter Inlet".
If the flow from the drain line is more than 0.4 L (24.4 cubic inch) per minute, replace the secondary fuel filter head. Refer to Disassembly and Assembly, "Fuel Filter Base - Remove and Install".EFLP Flow Test at the Primary Fuel Filter Inlet
In order to check the fuel flow from the EFLP at the primary fuel filter inlet, perform the following procedure:
Make sure the keyswitch is in the OFF position.
Disconnect the fuel inlet connection from the primary fuel filter head.
Install a suitable blank on the fuel inlet port on the primary fuel filter head.
Place the open end of the fuel inlet line in a suitable calibrated container.
With the keyswitch in the ON position, measure the input voltage at the EFLP. Record the result.
With the keyswitch in the ON position, measure the flow from the fuel inlet line. Record the result.
