I have a 88 13B that hasn't been run in a long time. It starts and runs but is sputtering when I give it gas at higher revs. Most likely I need to replace the fuel filter or filters on the car. This is a non Turbo. Does anyone known where the filters are on this car?

 

On my 87 the fuel filter was under the car, by the driver's side fender. Pretty easy to get to, don't forget to de-pressurize the system!

 

below the brake booster on the frame rail.

 

Thanks Farmerxr7. I found it. It should be pretty simple. Hope that is the issue. I don't want to entertain mucking about with the injector box.

 

injector box??
