I have a 1989 Taurus 24 valve engine. The car would turn over, but not start. For some reason a buddy of mine tapped on the fuel filter looking part, that is located on top of the engine, inline with the fuel lines. This part has 1 connection in and 1 connection out, so I assume it is a filter. The engine started after this tapping, so I feel the filter is clogging and he only loosened up the clog. This has happened again yesterday, so I am looking for the part, but auto zone can not find the part # and keeps showing me a huge 1 lb coffee can looking filter. The part in question is a little bigger than the size of a poker chip. where can I find this part #?
