Replacing HPOP o-rings

[choupique108]

I got the kit from ford to change the HPOP orings and i was wondering if anyone knew where I could find some good instructions on how to do them.

For anyone that needs the kit, the part number from Ford is 2C3Z9G804-AB
It comes with 3 o-ring, loctite, and some crappy instrutions.

HPOP O ring removal- no special tool required

I used this when I replaced mine. Pretty simple just takes a lot time to get the fittings out using the stubby wrench. You can only turn it a few degrees at a time. Also I didn't remove anything like the article says to. I just removed the fittings and then took the lines off the fittings.

Super easy to do. First thing I ever did to the truck was replacing the o-rings on the HPOP. Just remember to fill the HPOP reservoir otherwise you're truck will never start. Made that mistake when I did mine.

i guess it seems a little harder just by looking at it. There is alot of crap all around the pump. It dont look like its all that easy to get too. Im gonna tackle it tomorrow. Thanks for the tip on the resivor

The only way I was able to do it was with a stubby wrench. I mean you could take the lines off and then use a socket. I was not able to get the lines off while the fittings were still in.

... what lines are leaking two side ones or rear plug??..i didnt fill my hpop..truck fired up like normal...easiest way to make the tool is with a panel popper and just make the square cut out bigger, i never did them before either took 30seconds to take line off, once lines off i used an extension and i think its like a 24mm or something on my electric impact and it came right out..replaced o-rings fired up and watched for leaks... overall 10mins per one.. there really not that bad..

I got em changed today and they was not bad at all. I did not unhook the high pressure lines i just un screwed the fitting the changed the orings. It was very easy, just kinda time consuming. Here is what my old o rings looked like.
