Fuel Filter part #

[sjl2725]

I want to change my fuel filters. Bought the truck with 27k on it, and not sure if they have ever been changed.

The stealership gave me the FD-4609 kit and my manual says FD-4604. Before I go tearing into these filters and have to reinstall the old ones (which probably isn't healthy) in order to drive back and get the correct filter, can someone verify who is giving me the right info? I told the parts guy that the truck was a Job 1 from march of '07. Still insisted that the 4609 was the proper kit.

4609 or 4604

That sounds right, the early job 1's had a misprint in the manual for the correct filter number. I don't have my filter's number in front of me right now, but I know the manual was an issue in the early trucks.

Manual=FD-4604=wrong
Actual=FD-4609=correct

Thanks for clearing that up... I had considered the possibility of a misprint, but you never know.

Are there any tricks to changing the filter at the water separator? If I just pull that cap off, am I going to have fuel everywhere?? (I assume there isn't much of a trick to the engine mounted filter...)

the 4609 is the OLD filter..... There is a new updated filter FD-4617

yea there is.
first change the fuel filters only after you have less than 1/4 tank of fuel. second, loosen the cap of the engine mounted fuel filter first to release pressure (i do the lower one first and then the top one). with the bottom one, make sure you are wearing an old shirt, have opened the drain valve, have at least 6 inches of socket extensions, and have a drain pan below the immediate area.

You will get soaked in diesel and smell like a fuel pump for the next few hours. Other than those pointers, just go slow and make sure to lubricate the orings.

You will save yourself about $130 in labor costs.

Was just going to say... 4617 is the new number.

Use the 4617, the O-ring is supposed to keep the filter working, once it plugs up, instead of allowing the stupid thing to bypass.

And don't be a girl, get diesel on your clothes.

It drives the wimmins wild.

^^^What he said, except I get a kitchen pass when I smell like diesel. The wife hates that smell, so I do it early in the day and get the rest of the day to myself

$130 labor charges to change the fuel filters? I pay a local oil change place $35 to change both fuel filters. I wouldn't get diesel all over me for that...... not counting I am getting to old to climb under there!!

Thanks for the even MORE updated info!

Man I love this site!

I got it done. losened top filter first, drained separator into a bucket. Left separator open then losened the bottom filter till fuel started to drain. Although, I found it easier to use NO extensions so I could get more torque on the cap. Yes! There is ALOT of junk under there. I also found it easier to separate the cap and the old filter while it was up behind the wires. AND put the empty cap back in the same spot, then the new filter and snap them together while theyre up there. Less fidgiting around and less dirt on the new filter.

I didn't get any fuel on me at all and I had 3/4 of a tank.... Beginner's luck?

I did use the 4609 filter and the bottom side element had the new, added o-ring on it. Maybe the dealership went through thier stock and updated the filter kits with the new design???

I gotta re-iterate what others say... Thank God for this forum! I would be lost without it. Everything from DPF deletes to steering alignment to filter changes I've learned on here.... The Org rocks my face off!
