If you didn't have any problem before replace the fuel filter then you will not notice any difference. My old fuel filter was absolutely nasty too. There was black things stuff coming out of it.

 

I am changing mine today swell with 144k I picked up neat NAPA a napagold 3319 will see if it helps

 

done two of these now-one for myself and one for a friend.

None of you mention any leakage difficulties when re-tightening the fittings. I was terrified to over torque and damage the compression fittings at either end of the filter. Just wanted to chime in that so long as the compression fittings get lined up properly and you use a 14mm (I believe that was the size) wrench on the filter side-then crank down hard on the compression nut (12mm if I recall correctly).

My Russian mechanic friend actually lets the fuel pump do the work-pouring gas down the line and then torques down the compression nuts at each end to stop the leakage and visually verify they are completely tight.

Wear eye and clothes protection of course if you are going that route.

 

Tip: If you're having issues with leakage, use rubber washers. I used the one I got from replacing the starter contacts, it fit perfectly.

Please use safety precautions:

Use some kind of mask for gas fumes.
Please don't smoke while doing this job.
Work in open area & keep away from potential sources of ignition.
Wear personal protective equipment esp. goggles.
Purge pressure in system first by removing gas cap.
after replacing, turn ignition and check for leaks.

 

i would rec changing the fuel filter at least every 50k.....

 

I noticed leakage after my install. I used teflon tape on the threads and the leaked stopped
