That part # must be a 94-97 drain valve if it's held on by only 2 screws.
I'll bet that International has the later 99-03 drain valve.

Here's some photos of a 94-97 drain valve.

It was the only part they had with the o-rings so I took it. I just thought that it was unusual that the inner section fit into the stock ford housing, so I changed out that section instead of changing the 3rd 0-ring. Also unbeleivable that their part was $12 vs $64.

thanks,

I just stumbled on this thread after discovering a fuel leak on my 02, what an awesome thread! My eyes can't take the reading any longer so if someone can answer my question I would appreciate it.

My leak is coming out of the drain tube mounted on the frame on the passenger side of the truck. I do not have a leak on top at the fuel bowl and there is no fuel in the valley. Will replacing the o-rings stop the drip coming out of the drain tube? Thanks in advance.

Got er done in one hour............ No more leak! For those interested I got the o-rings at Grainger here in Phoenix. 25 count for $6.25....... Cost me 50 cents to repair. Couldn't have done it without this site.

OMG, this FAQ article just saved me from taking my truck to the dealer.
I bought the fuel bowl heater and o-rings for the fuel drain valve (Got the o-rings from Granger, if anyone needs some, I have 23 left)
I checked the size of the screw head that came with the replacement fuel bowl heater and it was 3mm hex head. So I went to the local Snap On man and bought a 3mm hex head socket. I could not get the socket to fit, so I did a search here and found out it was a #20 Torx head. Had both heater and o-rings replaced in 10 or 15 minutes with the help of a 1/4 air ratchet, which I Highly recommend for this job.

+1 more on the fuel drain o-rings.

In my case everything was fine. I drove 2.3 miles to the store (engine barely warm) no leak (I pay close attention to my stuff). Drove 2.3 miles home (engine now up to normal temp) and I smelled raw fuel. Look under truck, have small (silver dollar) size puddle of diesel.

Drove it 5 more miles to see where it was coming from, now it was really coming out!

I had fuel in the valley and coming out the drain tube.

Can't believe this happened so fast!

Anyways thanks to this site I changed out the o-rings in about 30 mins.

I used a 1/4" socket with a T20 bit in it. I used adhesive lined heat shrink tubing to lock the bit in the socket.

Thanks diesel stop!

and another one.....

another leaking fuel filter drain on an otherwise perfectly running 7.3 motor.

mine leaked a bit several months ago, stopped when I actuated the drain valve a couple of times. Now, in a week it has gone from a drip to a puddle.

Since it appears to be a common problem......and from what I have found to read about it the culprit is the ULSD fuel......I have decided to opt to rebuild the entire fuel separator/filter. I figure that:
1: if the o-rings on the drain valve are deteriorating due to the fuel, so are the rest of the o-rings....
2: the job of replacing the drain valve/ o-rings looks like a PITA due to its location....
3: The entire fuel filter housing is pretty simple to remove....which makes the drain valve fix that much easier.

bought the kit from www.dieselorings.com for 17.95 and figure at least I will have a bit more peace of mind knowing that I wont have to mess with it again.....
