Primary fuel filter

[PWM]

I removed my primary fuel filter today, I thought it would have some debris in it but not this much. I spooned out 3/4 of an inch of crud, it took about an hour and a half to clean it. Luckily it appears nothing got past the filter.

How long since it had been changed?

I thought it was done just before I bought the truck last year. Now I think it may have just been the secondaries. I will find out in a few days when I get to the secondary filters. The engine was re-built in 1991 probably then.

Did you buy your truck from a private party or from a dealer?

Also, how is your front license plate mounted to your truck?

That looks like an Ohio plate.

I bought the truck from a private individual, so I should have checked earlier. My front plate is held on with zip-ties until I weld some nuts to the grill and bolt it on, one of the many small tasks I have yet to complete. .

Thats some muck in that housing, did you replace the o-ring seal when you put it back

Not yet, the filter housing is still sitting on my work bench. It got dark and started raining/snowing so i quit for the day, AKA no shop.

Sorry for the double post. My computer has been having a hard time in the past couple of weeks on this site. I have pages fail to load and somtimes i get sent back to the forum index page while i am typing.

Don't be overly concerned about the quantity of "muck" in the primary filter, that's its purpose in life to collect this kind of junk and keep water from getting past it. It can probably hold a pint and still work well as long as the filter is changed or cleaned regularily.
Make sure that the drain cock works, so that you can drain the filter housing normally after everything is put back.
For those of you, who have seen this picture before, I apologize, but not everybody reads all posts.

Took care of your double post.....

Thanks, I think I got my computer fixed up and I am having a better time now. It took a while to clean the drain but I got it done and now it is back together on my bench. Earlier today did a search and found some of the pictures you posted in the past and looked everything up in the TM. When I took it apart the cone shaped washer was backwards under the spring and the spring was directly under the filter. I put it together the way the TM showed and your pictures helped, thanks. It does not appear that anything went past the filter but I was surprised to find a half can of chili and some corn in my fuel filter housing. I did find some chips of paint that is used on the inside of the military jerry cans, I checked my cans and sure enough it is chipping off. Time to get some new ones.

What is the correct procedure to drain the primary and secondary fuel filters? I found that when I drained the primary with all electric and engine off, it would drain and I could hear fuel drain back into the fuel tank at the same time (sucking air in to the drain-cock). I also tried it once with the power on (accessory switch) and , Wow does it flow! (and splatter all over, even though I had a 1 gallon pail under it) I would have thought a slow gravity drain would be most effective, but maybe pump pressure would "blow" everything out best?
And for the secondary, I have only drained them with "Everything off" , then closed the drain-cock, and then turned on the accessory switch and opened the bleed valve on top to bleed them after.
Is there a step by step procedure in a tech manual? If so, could someone point me too it?

Most non-enthuisiast deuce owners have no idea the primary filter is there. Sometimes it get's overlooked. As Bjorn said, don't be overly concerned about the muck in the bottom of the housing. My truck had the same ammount if not more. I wouldn't get concerned until the final and secondary filter housings looked like that. My truck was also missing components in the filer housing assembly's which I robbed off bad engines at my buddies farm. I was missing the spring, metal bell piece, and some o-rings. With no spring or cap the filters is just sitting in the housing doing nothng but soaking in fuel,make sure all of the components are there.

As for draining the housing, I also concluded what doghead said. You will get a couple of drops draining the petcock with the transfer pump off but that's it. When the pump is off the fuel system is sealed and when there is no air or fuel to replace the fuel running out, it ain't gonna run! Turn the pump on and, like doghead said, be prepared to take a diesel bath if you're not prepared.
