Remove mat from trunk.
Remove metal service hole cover.
Flip the metal service hole cover over. Inspect the gasket. If the gasket is broken or deteriorated, replace the gasket or cover. Because it could leak carbon monoxide into the car if the gasket is bad.
Remove the bracket that holds the fuel filter with a 10 mm deep socket and ratchet extension.
Before removing the fuel hoses, look at the filter to determine what side is IN and what side is OUT. So you can install the new filter in the same direction.
Remove the fuel hoses from the fuel filter with a big pair of plyers. If the hoses are stuck on the fuel filter, do not pull them with force. Get a flathead screwdriver, and put it in the corner of the end of the hose, then gently turn the screwdriver to crack the pressure holding the hose, and it will release the hose.
Install new fuel filter and reinstall bracket.
Verify that the fuel hoses are pushed fully onto the fuel filter nozzles. The fuel filter will have a hose stopper. Push the hose all the way until it contacts the stopper.
Reconnect the negative battery terminal.
Step 17: Fuel Leakage Inspection
. Some people may decide to skip this step. Use caution if you do this step, connecting the wrong data link connector terminals may possibly cause a malfunction. Carefully connect the specified terminals only.
Step 17 a:
Make a small jumper wire out of a scrap piece of wire, by striping about a quarter inch off each end of about a one inch piece of scrap wire.
Step 17 b:
Connect data link connector terminals F/P (fuel pump) and GND (ground) using a jumper wire.
Step 17 c:
Turn the ignition switch to the on position (do not start car) to operate the fuel pump.
Step 17 d:
Pressurize the system this way for at least 5 minutes to be sure of no leakage. Go back to the trunk and look at the fuel lines going in and out of the fuel filter. Make sure they are not leaking.
Step 17 e:
This procedure will also prime the fuel system.
Step 17 f:
Remove the jumper wire.
Step 17 g:
If there is fuel leakage, correct the issue.
Reinstall service hole cover, and reinstall trunk carpet.
