Fuel Filters

[D HD]

Yeah, you guys are great help. I was able to change everthing and not get any fuel going down my arm, and this was my first time to do this (just got the truck) Also the oil filter wrench was a great idea. I used the 3 7/16"-3 3/4" filter wrench... Still not fun but sounds better than what I was reading from some of you.

Yep, see figure 3 on page 6 in the enclosed .pdf.

The easiest way to change the HFCM filter with 4x4 is to use a long 18"-24" extension on a 1/2" ratchet; come at it from behind the xfer case crossmember. Only took me about 5 minutes to take it off and put it back on when I changed out 3 out of four filters a couple weeks ago.

I decided to not change out the aux fuel filter since it seemed to still be flowing well and it's not part of the truck fuel system. The fuel samples in the pic below are, from left to right: aux fuel filter, pre-pump fuel filter (first filter on left), and then the fuel drained from the HFCM. The fuel from the pre-pump and HFCM filters were so clean that I used them to pre-fill the pre-lump filter before re-installing the new filter. Both the aux fuel and pre-pump fuel filters have drains and it's easier and takes less time to drain them both than to drain the HFCM.

Hope this helps.

I changed mine about a week ago, but didn't lube the new o-rings. Does this mean I need to remove and re-install while re-lubricating the o-rings?

See the youtube video: YouTube - Motorcraft Powerstroke Diesel Filter Comparison There spike in the Ford filter that unlocks the check valve. Non-Ford filters do not unlock the check valve.

Ok guys... bear with me. I have new head gaskets and heads. I am ready to put together. BUT... what way does the gasket go? It looks like 4 sheets of metal riveted together. 1 solid sheet and if you flip it 3 smaller sheets? Please help!!

I just wanted to say how great this forum is. I couldn't believe what I was seeing as I watched the You tube video. The primary fuel filter I just removed from the HFCM on my '06 6.0 F250 was black on the lower half and clean on the upper - I knew this wasn't right but couldn't figure out why. I guess the filter I'm using can leave the housing half full of air which would explain what I'm seeing. Thanks Squiggy!

Also, heads up on online Motorcraft filter suppliers is a huge help. The prices are around 50% of what I'm paying....and to make it worse, I've apparently been buying inferior parts in good faith from what I thought was a reputable parts retailer.

Thanks folks.
