Fuel filter replacement
I attempted to replace the fuel filters on my truck today. Climbed underneath and tried to loosen the drain plug. No dice, it would not budge, and I didn't want to take a chance on stripping it.
I watched a couple videos on Youtube and one guy changed the pump filter without first pulling the plug. Other than the potential for a mess, can anyone see any reason why this is a bad idea?

Well its good to have that plug so you can drain the water if you get some in it
But at this point just pull the Big Cap and change the filter till you figure out how to get it out
Few guys had that problem hope they pop on and tell how they got it out
the real bad ones have to replace the cover plate housing
seems like other drilled it out IDK for shure on this
might could try epoxey an allen wrench to it and try IDK GOOD LUCK

I'll secound that, do what you need to do...even if it includes replacing the cover...to get that plug out. Otherwise you'll have no way to drain water out of the HFCM...you will need that ability some day...I've had to do it twice in the 5 years I've owned my truck. The updated plug is a much better design.

So, I went out today after having driven the truck for a while (thought maybe warming the pump up a bit might loosen thing up) and then got on it with a 6 mm allen wrench and a short piece of pipe for leverage. No go. Tried soaking it down with some Kroil and wrenching it again. Nope.
Anyone have a tip or trick to break this thing loose without stripping it out?
If I'm forced to remove the cover, what's the procedure for this?

Your talking about a steel plug in an aluminum part, that in it's self is more than likely part of the problem with why it's seized. Any water that might be in the fuel makes it worse...that's why the upgraded part is made of brass.
Some guys have tried an easy-out, not sure how well that will work...but your OEM plug is more than likely shot. Might try to epoxy a cheap allen wrench into the plug. This is my idea, pull the cover off (think there's 6 screws)...put it in a vise and try one more time to work the plug out. That may or may not work, either way I'd strongly suggest you look into the upgraded brass plug. May have to replace the cover if you can't get the steel plug out.

You wouldn't happen to have a link to the cover plate removal procedure or better yet, a video?

Just curious... have you never removed the drain plug before to remove or check for water/moisture? Even if your light does not come on, you always remove tis plug prior to a filter change... should be done every 15,000 miles or as needed.
Maybe go to the dealer and have them do it... so if it breaks they can either pay for it or maybe they will sell you the part at dealer cost?
If you pay them to change your fuel filters for you, they better do it properly... which means removing the drain plug prior to removing the alrge HFCM filter. (I would watch them do it to ensure it gets done).

I just bought the truck last Sept. I assumed (yeah I know, when one assumes something, it makes an *** out of you and me) the dealership would have gone through it prior to me buying it. Apparently not. Anyway, I ordered one of the up-dated plugs from Riff Raff Diesel and I'm going to try buying a set of impact allen wrenches for my impact gun. I'll start out on the lowest setting and work my way up until he old plug either comes out or strips. If it strips, I'll be buying a new hcfm cover.

Hi,
One thing to try,
If you are going to use an impact driver. Get one of the hand held ones that you use a hammer to hit. This puts some down force on the plug and helps to not strip the flats out.
The new updated plug. Does it stick out some? If so I must have the old style still.
Only had the truck about 2 months
I found you a cover change video on youtube

Thanks

the replacement plug, which most Ford dealers do not stock as it is a specialty plug made for medium duty trucks, has an oversized **** on it.
This **** just needs a light tocuh with a pair of adjustable pliers and it opens up very easy. It is the rubber o-ring that seals as well as the threads, but one does not have to overtighten to get it closed (like the stock factory drain plug).
The new plug can accept an allen wrench, but I never use it due to the lack of room and the ease of using an adjustable wrench.
Good luck,

I need to get on FTE more often! I wasn't putting you off atomicglock...just been a busy couple of days at work.That's correct, it's not an aftermarket part. Here's the part numbers:
Ford: 6E7Z-9C082-A
Navistar: 2589259C91
The link I post above is these part numbers...just offered through RiffRaff. Going off the top of my head, this update plug is originally from the "cab forward" trucks Ford was building for a while. I think they were called LCF...but I don't remember.
