How many fuel filters on a 03 E350 7.3 Power Stroke Diesel?

I have a 2003 Ford Econoline E350 Super Duty 7.3 Power Stroke Diesel and I want to replace the fuel filter or "fuel filters". I keep hearing conflicting opinions on how many fuel filters there are...even from the Ford dealer parts department themselves. I would like to speak to someone in the service department at the dealer but you know how that goes......Anybody have a concrete answer on how many fuel filters? 1 or 2? and is it or are they easy to change myself?

I'm pretty sure there is just the one on the 7.3L. The 6.0L has two, so everybody probably had it drilled into them there are two, thus the confusion.

Ah this one is fresh in my mind

There is 1 "Fuel Filter" on the top of the engine. Then there are 4 other "screens".

On the side of the Fuel Filter bowl there is a pressure regulator that has a mesh screen (clean this when changing the filter)

In the fuel tank there is a mesh screen on the bottom of the pickup tube.

Also in the fuel tank pickup there is a mixing chamber that has 2 mesh screen inside (bloody stupid idea IMHO).

Checkout some photos and details on my posting here http://www.expeditionportal.com/foru...-E350%29/page3

In the very near future I will be adding spin on CAT filters and an extra lift pump to both of my 7.3's. I have already got rid of the in tank screens on the ambulance conversion as one dose of crappy fuel will cripple the vehicle and it is not a trail repair situation. Hopefully I will remember to take some photos and make put up a thread for later reference.

In fuel tank mixing chamber screens.


Fuel pickup modification showing the pickup umbrella but not the actual screen.


After pulling the mixing screens I put this temporary filter in before the lift pump. $6 at NAPA and I can change it in about 2 minutes with the wingnut style hose clamps.
