How hard is it to change HPOP o rings?

[STLstroker]

Has anyone changed the o-rings on thier HPOP. mine is leaking either in the seals or on a sensor but i am kind of hesitent on fixing it myself since i dont really know much about it.

How do you know it's leaking? Is there oil in the valley? Pulling the hpop isn't that bad, at least with the fuel bowl out of the way it isn't. Bout 10-15 mins maybe less to have it out of the truck and in your hands. If it is just the o-rings on the hpop lines, I think bill??? at dfuser has replacement o-rings and he is a sponsor here I think. Good luck.

i am actually not sure where it is leaking. it seems to be leaking from a sensor going in the hpop. i am getting oil in the valley which is seeping down the drain hole onto the ground. as i look at the quick disconnects i dont see any oil dripping, but it is leaking underneath the hpop where i cant see it.

*bump* ???maybe the hpop gasket is leaking? All of your intercooler boots are tight right? The oil vapor from the CCV might be slowly building up in the valley causing the leak. I have a small boost leak myself and there is oil in the valley, I just need to trim up my intake boots a little to get a good connection to the compressor outlet. Just a thought?

changed mine today , at first thought it was rear main but after readin here i took a good look in the valley and found the culprit. hpop o-rings.
i went ahead and got the seal kit from the ford house @
$35 for three o-rings and a tube of lick tight "hard to take that one"
but it was the right parts.
i did the job with the fuel bowl in place.
the quick connect tool was a must.
once the lines were off a real long3/8 extention and a
19mm deep well socket worked well on the fittings
a 18mm ratchet wrench made quick work outa the plug
on the back of the pump.
all and all not to hard of a job. would have only took
abot 30 min if i didnt loose one of the springs that come
out of the housing behind the line fittings.
that took about 2.5 hours to find.
once i found that needle in a hay stack it was back in and truck running.

main word of advice i can say after doing this job ......
leave the springs in place , use a piece of coat hanger
about 4 inches long thru the coupler to guide on to the spring, get the fitting started by hand and then tighten er down.
many thanks again powerstroke.org
yalls advice saved me another ton of $$
and kept my 03 7.3 psd going and without leaking any more.
