I tried to replace the fuel filter in my 1993 Subaru Legacy, non-turbo, using the Chilton manual. I see the where the filter to be replaced is, but the instructions say to reduce the fuel pressure by disconnecting the electrical wiring connector from the fuel pump. Hence my problem…I can’t find the fuel pump or the electrical wiring connector. Although the manual says that it is beneath the back seat under cover plate, there are no cover plates underneath my car’s back seat. Also, any advice on removing the fuel lines from the old filter without making a mess would be much appreciated.
Pull the fuel pump fuse and crank the starter. That will eliminate the fuel pressure. Then engine may start, but won’t run very long.
Fuel filter replacement is, by nature, a messy job. Be prepared to handle some spilled gasoline.
