So the 3617 it is for me. Any tricks to the switch? Fill with fuel? Bleeding air? Thanx in advance
New fuel filter and injectors

Some fill with ATF to lube the pump, some with fuel. I would fill it with one or the other just because if you don't, the priming process takes awhile. ******* starters if you are running a mechanical pump. If you fill it 1st, it usually starts right up. It may stumble a little to get any air out, but you should be fine.

Do the change with a warm engine and fill up the new filter with diesel or ATF before you screw it into place. It is much better to be working on a warm engine that WANTS to run over a cold one that may be struggling to fire even without the filter change in the equation. It will stumble a bit but should take and smooth out relatively quickly. Gary will also recommend to put the diesel into the filter from the outside in so it will be filtered as well. It's a bit tedious but is good practice and separates the so so mechanics from the top notch ones.

I'm sure I'm gonna get flamed for this, but in my region, water in fuel from pumps isn't that uncommon. Two years ago, I filled up and had my light come on and then actually shut the truck off. I always drain my filter into a clear bottle so I can see what it looks like. That tank of fuel had over one full beer bottle of water. I use the stock Racor made filter with water separator, it comes with a new oring and I always change it and I've never had any leaks at the fuel filter, but I can understand how agravating fuel leaks can be. I've seen too much water hurt diesel engines (especially marine diesels) so IMHO I will never bypass/eliminate a water separator. Water in a gasser fuel system: I couldn't care less, but not diesels. Again, just my .02 worth and personal experience.

+1 on a warm engine and putting the fuel/ATF on the filtering side of the filter, no different than an oil filter.
No flaming, just letting you know. All 3 Napa filters are water separators, too. The only thing the 2 w/o the bottom screw on part don't have is the sensor for the light. It is handy when it works. Just not sure if mine does.
I kept the bottom piece just in case I decide to go back.
X3 on the working with the engine warm. Very good point!!!

Hmm. Must just depend on brand and where it's purchased from.

I like all the comments so far... Very good ideas posted about filling the filter and doing this on a warmed up engine. Now some talk about why I feel its best to fill the outside ring of holes on the filter.. No matter how clean your can of fuel is there will be dirt in it. So why not make the filter do it job. Make the fuel run thru the media and help your pump last longer. Now about adding atf to the filter.. Great idea too but... Get the engine running on the diesel atf mix till you hear the engine sound differantly. Then shut it down and let it sit overnigth. This atf will clean the pump and the injecters. The next morning start run it like you stole it. That flushes the crude that may have become lodged in the pump or injecters. It can't hurt anything doing this and usually helps if you have not been faithful with fuelk additives. I run the motorcraft fuel filters that are the two piece. Of cource I don't buy them from Ford but get then on ebay when they fit my budget at the time. I originally started running the Frams in fuel and oil when I got my truck.. But I learned later on whats the best to be useing... I'm still working on the 99 to 03 fuel filter modification. Then all I will have to do is open the filter canister. Pull out the filter and push in the new filter... No more leaks.. No more costly filters either... Just some engineering left to do...
