Name is XXXX XXX i will assist you the best i can, please Only accept if you are happy with my answer.

This is strange as the fuel pump module only has a strainer as the fuel filter is out side of the tank .

What i suggest you do is check the filter as shown the the fuel filter instructions below .
FUEL FILTER REPLACEMENT
1.Reduce the internal pressure of the fuel lines and hoses and perform the following operations.
A.Disconnect the fuel pump harness connector in the trunk room.
B.Start the engine and, after it stops, turn the ignition switch to OFF.
C.Disconnect the battery negative (-) terminal.
D.Connect the fuel pump harness connector.

7.Disconnect the vacuum hose from the pressure regulator, and plug the end of the hose. Measure the fuel pressure at idle.

Standard value :320~340 kPa (3.26~3.47 kg/cm², 46~49 psi)
8.Measure the fuel pressure when the vacuum hose is connected to the pressure regulator.

Standard value :Approx.255 kPa (2.57 kg/cm², 37 psi)
9.If the results of the measurements made in steps (7) and (8) are not within the standard value, use the table below to determine the probable cause, and make the necessary repairs.
