Where in the world do you find the fuel filter in my car that is listed above. It is a v6 2.8, carburetor not injected. Please please help. Any one else have problems with mysterious shutting off problems? :(

I am not 100% sure, but it looks like the fuel filter is inside the fuel tank. Sounds like it may be located on the sending unit/pump in the tank.

I found one thing that said that it was just below the carburetor or under the pass seat and I forgot the rest, but I cannot find that article again. It said the injected kind is in the fuel tank.

This is a 2.8 with a carburetor? I cannot remember an 1986 with this combination.

Well, if it has a carburetor. It should be a varijet. The filter is in the inlet to the carburetor.

I found out it is in the carburetor. I am still having mysterious shutting off problems even after I brought it to the dealer to work on it. If any one could help I cannot find the flasher for the blinkers.

I know these posts were forever ago, but I have this exact same car with this exact same problem. Just wondering if you had any breakthroughs.

We need to see if you have spark when the engine stalls so we can determine if it is fuel or ignition related.

Here is a guide to help you check for spark look toward the bottom of the guide:

Please let us know what happens.

Suggested Repair

On this carbureted 2.8, the fuel filter is at the carburetor inlet. For the unexplained stalling, check for spark when the engine dies to determine whether the problem is fuel or ignition related.

Conversation Summary

The owner of a 1986 Buick Century with a carbureted 2.8 V6 asked where the fuel filter is and mentioned unexplained shutting off. One reply suggested the tank, while another said a carbureted Varijet has the filter in the carburetor inlet; the owner later confirmed it is in the carburetor. An expert advised checking for spark during a stall to distinguish fuel from ignition problems. The turn-signal flasher location was not answered.
