How to Replace the Fuel Filter on a 1993 Ford E-350

60

The Ford E-350 (short for Econoline) cargo van is the 1-ton version of the Ford E Series (150 for 1/2-ton and 250 for 3/4-ton) and is designed for hauling the heaviest loads. The fuel filter goes in between the fuel tank and the engine. Its purpose is to filter large particles out of the fuel so that they don’t get into the engine. Since gas is sprayed in a fine mist inside the engine, any large particles could clog the system, causing the engine to fail. Ford recommends replacing the fuel filter every 15,000 miles.

Replace the Fuel Filter

Disconnect the negative battery cable from the battery. Connect a fuel pressure gauge to the Schrader valve at the tip of the fuel rail. The tip of the fuel rail is near the top of the engine where the fuel is injected into each cylinder. Open the manual release of the fuel pressure gauge to release pressure from the fuel system.

Place a drip pan underneath the fuel filter to catch any fuel that drips out when you disconnect the fuel lines. Disconnect the fuel lines from the fuel filter, located on the frame rail underneath the van, with a fuel line disconnect tool. Remove the old fuel filter and put the new one in its place. Reconnect the fuel lines by hand or with a wrench. Reconnect the negative battery cable.

Tips & Warnings: Avoid working around open flames while performing this repair.
