[AT] O.T. 7.3L Ford Diesel

[jahaze at aol.com]

Thanks Arthur,

I have a 1997 7.3 Diesel and have never noticed any puddles under the truck.  I'm in Michigan so it get's cold quite often.  I wonder of this was only a problem in the newer 7.3's?

Enjoy, Joe

Hello list(s)
Several folks on the list have Ford 7.3L Diesels and from time to time have
ittle problems and ask for opinions or help. Here's a money saving tip for
ou who can do your known repairs.
Monday we had a little cold snap here in mid-Florida. Thirty-one degrees F.
 waited until things warmed up a bit, 36F, then drove three miles to the
ourt House to turn in a lic. tag. When I returned to the parking lot, I
oticed a rather large puddle under my truck. I knew I hadn't been running
he A/C, so it couldn't be good news. And it wasn't; it was diesel fuel. I
ped back to the shop and popped the hood. Investigation lead to a leaking
rain valve on the fuel filter.
I called Ford Parts Dept. and was informed that it is common for the valve
o leak during a cold snap an the fix was a complete new valve assembly. I
sked the price and almost spit out my teeth. My cost was $51.75 with a list
f $75 and change. They told me they had sold 4 valves that morning and were
ut of stock for a few days.
 That turned out to be good luck for me.
I had looked in the shop manual at an Illustration of the fuel filter body
ssembly and knew there were two "O" rings tom seal the valve body to the
ilter can. Of course F-O-R-D doesn't sell the "O" rings.
I removed the valve for a look-see. I noticed the "O" ring was thick and
lmost a "square cut" outside and the inside hole was beveled on both sides.
 cleaned off the flaking yellow dye coating, turned the "O" rings over.
his made the "O" ring "stand" off a few thousandths and I knew it would
eal against the "ball" on the spool valve. I removed the "spool" valve,
emoved the "O" ring and replaces it with a common xxx108 "O" ring and
eassembled the valve and re-installed the valve on the filter can. Walla,
o leaking fuel and I'm $51.00 better off.
I hope this little bit of information will help one of you some day if your
alve goes to leaking.
C'ya,
Arthur Southwell
