Drain The Fuel Filter
Ive been wanting to remove the fuel filter and pour the contents out into a glass jar. But I understand there is a drain on the bottom of it which would do the same thing much easier. Only you cant see the bottom of the FF and I could not figure out what the heck was under there and how to accomplish this task.
I have learned to be cautious and patient. I do not want 20 gallons of diesel fuel to run all over the place from a botched drain attempt.
Well after a month I figured it out! I disconnected the drain pipe and made it so just the two inch rubber piece was attached to the filter so I could get a glass jar under there to catch the stuff. By feeling around I felt the round drain wheel.
So I turned the round drain wheel around and around and...
Nothing came out!
What gives?
BTW I got the air cleaner off and so was able to check ALL the glowplugs with a 12v test light. Everyone lights!

The drain could be blocked, who knows how long its been on there, and how much crud could have accumulated.
All you're going to get out of the filter is what is in it, not 20 gallons. Its the high point in the fuel system.
Theres been a lot of posts about fuel filter options, on just yesterday or the day before with some links to what you can replace it with. Remember to fill the filter with fuel before installing, that will help shorten the cranking when restarting the truck. Its best to replace when the engine is warmed up as it will restart a lot easier.
BTW, I know its been said, but you're wellman glow plugs probably won't last, so don't get your hopes up too much with them.

Theyre autolites.
Yeah one was bad and I changed it. The jobber only had ALs so thats what I put in.
Actually I dont KNOW what they all are. I just took one out...
It only has to start once a week, drive to work 6 1/2 miles away, and return later in the day.
Unless I find something for it to do.
This is kind of like a farm truck. Its a learning experience.
The thing is...removing these things might be real trouble if the end of one breaks off. I really dont want to kill this truck prematurely.
God knows how far off the End is.

Well I have to say no body has done very much to this truck in a few years I would say. All eight plugs test out with a light so I assume they are good.
If they crap out I will be the first to say.
Tomorrow morning is a 32 degree start the coldest so far!
