Fuel Filter REPLACEMENT Gasoline Engines The fuel filter is located behind the fuel inlet connection on the carburetor. On 1976–87 vehicles fuel filters incorporate a check valve and are not interchangeable with earlier years. Replace the fuel filter every 15,000 miles (24,135 km), or sooner if engine flooding is a problem. Fig. 1: Hold the large fuel inlet nut on the carburetor while using a flare wrench to loosen the line connection 1987 Cutlass Supreme not turning on. Think fuel sy - 86681247.jpg

  1. Using an open–end wrench (preferably a line or flare nut wrench), loosen the fuel line connection from the larger fuel filter nut. You will have to hold the other nut with a wrench to keep it from turning. Most of the time these units are quite difficult to remove. It is a good idea to apply a lot of penetrating oil to the threads and then tap the nut lightly.
  2. Once you have the fuel line disconnected from the carburetor, remove the larger nut from the carburetor with a box–end wrench or socket.
  3. Remove the filter element and spring from the carburetor.
  4. Check the element for blockage by blowing through the fuel inlet end. If the element is good, air should pass through easily.
  5. Once you have checked and/or replaced the filter, reinstall the carburetor nut and the fuel line. Be careful not to strip the threads. Fig. 2: Install the new spring and filter in the order they were removed 86681248.jpg

Need to change fuel filter on 1986 cutlass supreme oldsmobile where can I find it t change it?


You'll find it in the carburator. Unhook the fuel feed line from the front of the carb and undo the large nut directly where the fuel line connects to. The filter is there.Pay attention to how the filter comes out and put the new one back in the same way. Hope this helps.

I am having a similar problem, but there is no check engine light. It seems that mine dies at the light or running, if the rpm's drop. I am wondering if the Idle air control valve is bad or possibly the ERG valve?

Where is the turn signal flasher located on a 1987 cutlass supreme. I have no turn signals and have changed all the bulbs. Help!


The flasher is located on the fuse block. The other thing that may be wrong could be the actuall switch for the turn signals which is located inside the steering coloum.
