The location of fuel filter on 1991 olds regency elite

You might benefit from the 96 Regency Elite factory service manual purportedly available by a download for $22, if scrolling through pages or using CTRL F to hunt through a PDF is something you are comfortable with. I have no idea if it tells you to check for rust in the fuel tank. https://www.tradebit.com/filedetail.php/281883502-1996-oldsmobile-regency-service-and-repair-manual

The Haynes group is of course more familiar and there seems an aside mention of the 96 being covered in spite of the title. https://haynes.com/en-us/oldsmobile/regency/1997-1998

Regarding videos, I encounter such for the Olds Bravada and the Olds Aurora, both 96 models: https://www.youtube.com/watch?v=dO3QkeMTwP0

Question edited for clarity.

Check out the previous Fixya question with answer, and the other information in the link. It is a known issue.

I also have a 91 Regency Elite, My cruise control switches are located on the blinker stalk.

Remove the crankshaft pulley,the harmonic balance,with a puller made for this,then you can replace the sensor,and align it,if it is not aligned,it will break it.

it is the automatic load leveler that pumps air into the back shocks to level the car so it rides better when there are lots of people or weight in it. it is in the frontof the car opposite the battery, just disconnect it. had the same problem on my 1990 olds 98.

Based on the information you have given to this point, I am just going to give you a few possiblities. Have you had a tune up done recently? Air filter been checked or changed? I am not in any way trying to sound sarcastic so I apologize if I come off that way.Those would be my first things to inspect if I were ask to look at your car. I would also check fuel pressure and inspect the fuel pressure regulator.I would consider these things and go from there. I Hope this helps you but please let me know if you need more information on what to do next but I may need some more information at that time also .

iv'e had the same problem. mine was the starter wire had a split in the wire under the plastic. i cut wire and wired it directly to the bolt.

my fuel filter is located right behind the pass side tire on the inner side of the frame.

it is under the back by the fuel tank
