Fuel Filter Question
I just got a 1988 F SuperDuty 7.3l IDI 5 sp manual and have a question about the fuel filter on the top side of the motor
The fuel filter is leaking fuel slightly and there is some type of connection on the top that has been siliconed over.
On the side nearest the center of the engine there is a broken wire that seems to be a live wire hanging loose.
On the bottom side of the filter is a push on connector hanging loose
Question to some one is what are the extra wires needed for ?
Any help is appreciated
New be here too

The connection on the top is where one wire goes it is the fuel heater. It is pretty for it to start leahing and access to repair it is inside the filter header. The other wire is probably the water in fuel light wire that connects on the bottom tank to the filter.

tdspurrier,
Welcome to FTE and the IDI diesel forum.
You may also have a filter restriction wire in that area also.
The filter restriction sensor will be in the fuel filter header beside the fuel inlet line and schrader valve if your truck has one.

I have never seen the need for the fuel heater, but if it leaks it causes real hard cold starts after it sits overnight. FTE is about as good a manual as you can get. I like the proffessional motor manual but they are expensive and I don't remember who I loaned mine too.

Every once in a while you can get Helm's manuals on Ebay.
They are as good as it gets for manuals, but usually cost about 100 for the set.

Thanx for the good words ..
I do have a this "You may also have a filter restriction wire in that area also. " and it looks ok
If the books are expensive are there any good online drawings etc .. I hate to sound so naive in having to describe everything ...
Future plans for the truck are a true dual exhaust and fixing the pumpkin in the air filter

Do a search on this forum, for fuel filter head. Somebody did a step by step demonstration on the removal of that heater element and o-ring replacement, with pictures.That way it won't leak anymore, and you should have easier starts. Don't be like me and rip everything apart and try to plug that hole and break the filter head. When 30 cent's worth of o-rings would've stopped the leaking.

I have the Chilton's 1965 - 1986 Ford F-Series Truck manual and it's fine for me. $20 or $30 at Carquest. It gives me 90% of the information I need, the other 10% comes from here on the forum. The manual is nice for torque readings and torque sequences.
I also have the Haynes diesel manual. It covers the IDI's, Powerstrokes, and the GM diesels. Another $20 and it works fine for me. Picked this manual up at Advanced Auto.
