Ford F350 6.7 L fuel filter

[agesilaus]

I really am reluctant to post this since I know it will attract a flock of negative comments. I expect to see: "The Ram fuel filter is made of aircraft grade titanium and is platinum plated too...."

But this is something other 6.7 owners should know. I was taking off the chassis mounted fuel filter housing an hour ago when the plastic 'nut' on the bottom snapped right off. This housing has always been tough to remove and replace. It groans and squeaks loudly as you turn it.

I had it 1 1/2 turns off and was able to use a strap wrench to get the housing all the way off. The strap wrench makes a very poor fit for the housing so this would not be an option to remove it normally.

I've heard on the Powerstroke forum that you need to use a six point socket to remove the housing not a 12 point. Apparently this must be fairly common the Ford parts guy told me that they been seeing this happen and he ordered four housings and has one left.

The new housing comes bare, you need to recover the electical fitting (unscrews easily) and the drain valve from the old housing. Rumor is that it costs $25 for a new housing. Will see in the morning.

I noticed the last fuel filter installation I did that the green o-ring had some type of gel lubricant on it that I don't recall seeing before, so I'll see how it comes off in the next couple of weeks when I'm due for a filter change.

I use a standard hexagon (6 point)socket to remove the housing and I'm careful when removing the housing knowing that they are a bit cheap. There's some small strap wrenches I've seen but never purchased that might do the trick.

I've been tempted to buy a spare just in case mine does break.

Any idea what size 6-point socket is needed?

Broke the secondary fuel filter cap on my old 6.0. Friend that works at O'Reillys says they keep six of them in stock for just such occasions. About $20 for the replacement.

The fuel filter housing lid on both my 5.9L Cummins Rams were plastic. Easy to break if over tightened. I got lucky and never broke one, but I can see how they would be easy to break. The Duramax also has a plastic air bleed screw on the fuel filter housing that many owners replace with a metal (aftermarket) one.

They all have cheap plastic parts in areas they shouldn't IMO.

Good tip for other Ford 6.7L owners.
