6. Before discarding filter/regulator assembly, inspect assembly to verify that 0-rings (Fig. 24) are intact. If the smallest of the two 0-rings can not be
found on bottom of filter/regulator, it may be necessary to remove it from the fuel inlet passage in fuel pump module.
INSTALLATION
1. Clean recessed area in pump module where filter/regulator is to be installed.
2. Obtain new filter/regulator (two new 0-rings should already be installed).
3. Apply a small amount of clean engine oil to 0-rings. Do not install o-rings separately into fuel pump module. They will be damaged when
installing filter/regulator.
4. Install new gasket to top of fuel pump module.
5. Press new filter/regulator into top of pump module until it snaps into position (a positive click must be heard or felt).
6. The arrow (Fig. 22) on top of fuel pump module should be pointed towards front of vehicle (12 o'clock position).
7. Rotate filter/regulator until fuel supply tube (fitting) is pointed to 11 o'clock position.
8. Install new retainer clamp (clamp snaps over top of filter/regulator and locks to flanges on pump module).
9. Install fuel tank.
