E B P S Question
Are there any symptoms to indicate a problem with the tube and sensor being clogged. I'm asking because I am leery about trying to remove the sensor for fear of twisting the tube. So, I am doing the if it ain't broke don't fool with it thing. But with all the miles I have put on without ever looking at it I have become concerned that it may be a problem.

There's a 9/16 under the bracket. Hold that with a stubby open end. That way you won't bend the bracket.

Doing this myself today. Hope it makes some difference for me. I went the route of a new sensor and new tube. I'm assumming mine has never been done and with 200k miles...I'm sure it is pretty useless at this moment. Had a EBP code of some sort on the last scan so there is definitely something up with it. Will let you all know the results, other than the standard MPG increase, if I see anything.

I just replaced both of mine last week. There was a hole burned through the tube right about the middle of it on the 45d bend. Also the sensor was so clogged up with this hard crystalline black soot that I decided it wasn't worth trying to save and bought a new sensor. It was putting out some odd readings at idle so it was electronically bad. It had to go.
The passage throught he bracket was clogged halfway and the stuff had to be reamed out it was so crystallized. Same with the exhaust manifold passage.
Made no difference in throttle response, but now the EBPV when it closes on the warmup cycle, doesn't close all the way and make that hissing sound as loud. It's acting like the ECU is looking for a certain pressure thresh hold and then not going any further.
The new tube that I bought from Ford was stainless steel, so I hope this is the last one that I have to buy.
I am looking forward to getting a mileage reading next fill up.

Well...my little project ended up being a disaster. I could not lossen the tube nut for the life of me. Ended up bending the bracket such that it is not usable and had to take the bracket off. Probably easier to take it off to begin with. Anyway...I obviously don't have another bracket handy (neither does dealer) so will be a couple of days before I'm going.
Question. The 'bracket' covers a 2-3 inch hole on the bottom of what I assume is the HPOP. Needs sealant of some type when it is reinstalled. My question...why in the heck would the engineers not just put the bracket somewhere instead of making the bracket cover whatever this hole is. What is the function of that hole anyway?

Well...answered my own question. The backet covers a hole that is access to the HPOP gear drive so I do guess it serves a purpose. I sure wish I had just taken that barcket off (with EBP tubing) and taken the tube off on the bench. That tube nut was so d#^m tight it took me and a buddy a little struggle with some breaker bars to get it off.....and that was when it was no longer in the truck. Had I taken the bracket off first, I wouldn't have bent it and would likely be driving now instead of waiting for a new bracket to arrive. Oh well...live and learn.
For those doing this job....two small bolts get the bracket off easily....rather than using a crow's foot wrench, another wrench, 3 arms and some struggle.

I gained close to 2mpg when I cleaned mine out, but I also made the change to 5w-40 synthetic oil the same week...so I can't give the credit exclusively to the EBPS valve alone. I couldn't get mine off the top no matter how hard I tried....I reamed it out still attached on the top with the weed-wacker line, worked pretty good still!

Boy after reading this, did I ever get lucky. 205k miles, it had never been removed. The sensor came off with very little effort, tube was nearly whistle clean. I put the new sensor on anyway. But of course I have to wonder why some of us have clogged up ones, and mine was nearly in perfect shape?
