George look in front of the HPOP and see if you see anything. My sensor is between the HPOP and the fan.

George, it goes from the pass. side exhaust manifold, right in front, and curves up to the sensor on the pass side on top of the hpop resevoir and hooks up. It's like 14-16 inches long with some bends. If you look up from under the truck on the pass side right in front of the crossmember you should see the fitting and line sticking out of the manifold.

Part# I got from Ed was F4TZ9D477A. Mine is behind the hpop

Acoording with the numbers in this thread (including the bag of the pics from Neal: F7TZ-9D477-AA in front of the HPOP), it seems that the rigth numbers and the name of the tube are:

Exhaust Back Pressure Tube<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com

ffice" /><o

></o

>
(Ford) F7TZ-9D477-A (94.96 ; earlier models, behind of the reservoir)<o

></o

>
(Ford) F7TZ-9D477-AA (97-up; later in front of reservoir) but in some cases in this years may mount like earlier models.

BTW the # part for the sensors also are different:
Exhaust Back Pressure Sensor
(Ford) F4TZ-9J460-A (94-96; mounts on bracket above oil reservoir) NOTE: Part Number F4TZ9J460A was Superseded with 1C3Z9J460AA
(Ford) F7TZ-9J640-AA (97-up; later in front of reservoir) may mount like earlier models (I dont know if this one, also was superseded for other number)

Ed emailed me back and said he was getting me the updated part number one not taking any chances so maybe that is what you have there. I trust Ed, hasn't failed me yet.

When I type up the first part number for the tubes you gave me in eds site it doesn't show anything. The second one does. I think that first one is wrong and is what I ordered.

I also put the numbers in Powerstrokeshop and doesn´t show anything. Maybe they have been superseded
