Sorry guys to start a thread that yall have probally seen a million times... but im looking for some tips n steps to changing out my fuel filter on my 94 7.3 factory turbo idi engine... i tried searching for it but came up with other threads n topics... thanxs in advance!

 

If you're just wanting to change it I unscrew it and pour MOST of the diesel back into the tank with a long funnel, I slowly pour it with the filter at an angle and leave some in the bottom with any crap that was in it. You could just discard the whole thing but I'm cheap. Also you'd have to deal with all of that diesel when you throw it away.
Then fill the new filter with Diesel Kleen etc. or ATF, oil the gasket, screw it on and crank it over.

If you are asking about replacing it with a different filter system that's a whole different question.

 

I just want to replace the whole entire filter...with a new unit
-now i didnt search to see which is the best but i jus went ahead n purchased the Advance filter, since i felt ill be changing some things around it proably wont be on there very long but since im new to the none powerstroke i didnt know how to go about doing things...

 

A huge tip is to run the truck to operating temp, it makes it 10 times easier to start. And also when starting it again, floor it and sometimes it will stay started, but generally it will die and then you have to crank it 2-3 times in 20 second intervals.

 

Thanks Dean for the tip...

 

I also don't recommend reusing the old diesel, due to the risk of contamination, now true its an almost zero risk, but its just not worth the 75cents worth of diesel you save, but I do recommend filling the filter with either ATF, Diesel Kleen, or Lucas Fuel Treatment.

I've used ATF and the Diesel Kleen before in my IDI filter, but I've used the Lucas Fuel Treatment to fill the filters on a John Deere 4440 and it ran great on that stuff.

 

If you go to this page...... you will see all the parts of the filter.

I first drain the water separator on the bottom by unscrewing the knurled wheel and collecting about 1/2 cup of fuel from the steel drain line in a plastic container. Close drain and remove the WIF light connector and the drain line hose from the filter. Using a filter wrench unscrew the filter from the head, trying not to spill the remaining contents. Look inside to see if any water or crud has passed through the filter system. Now drain the filter then remove the filter base and clean it.

Assembling the new filter, place the new slightly oiled oring in the separator base groove, screw base and filter together hand tight. Fill the filter with clean diesel or fuel additive via the outer small holes until 1 inch below the top, lubricate the upper filter seal and screw the filter to the header. Hand tight is usually sufficient but 1/4-1/2 turn more with the filter wrench does the trick. Now retighten the base by hand slightly if required. Install WIF connector and drain hose.

With a helper, purge the air from the filter by pressing on the valve stem in the schrader valve (use a rag to catch fuel) while starting the engine. Wipe up any spills jobs done. Note stumbling may occur until all air is removed from the system.

Bleed air from the Schrader valve, engine should start when fuel is present.

The above is of course you still have the complete filter setup with base......

 

I forgot to maention that I ditched my facotry "water seperator" air intrusion/fuel leakin' SOB and replaced it with a NAPA water seperator in front of the tank selector.
The stock filter head has a filter with no seperator now.

I don't worry about reusing the "contaminated" fuel from the filter as I have three filters on the truck and that fuel gets returned to the tank and back through the filers about a bazillion times.

 

Baldwin filters makes a filter that replaces the two piece setup for a pne piece screw on filter. Its what I use. The # is BF1222SP

The SP is crucial if your want to haave the WATER IN FUEL port.

Do you know what the thread size is on the factory filter head?

 

Sorry, not a clue. I wish they had left it the same thread as the 6.9L.

 

I'm not sure, maybe 1"??? Anyway, it is a very common size on top. A WIX Element # 33411 will fit, it is the same filter, just has a made in water separator instead of the stupid screw on thing.

 

That's probably the same thing I put on but mine's a NAPA gold, expensive sucker but it's not leaking.
