Where is the fuel filter located on a 1998 Ford E-250 4.2L?
I'm not sure if this is the same, but I just changed the fuel
filter on my 1997 E250 4.2 liter van. The high pressure fuel filter
is located under the driver's side door, inside the frame rail,
forward of the fuel tank, just behind what I think is the catalytic
converter. It is tucked up inside the driver's side frame rail and
is held in place by a hose clamp. You will also need the a/c and
fuel line quick disconnect set. I bought mine from
Checker/kragen/shucks. It was made by Powerbuilt part # 648424.
