I hope your line removal tool is in the tool box in your truck, too, Ken. I ended up making my own line removal tool from some spare 1/8" flat bar I had on the work table in the garage... wasn't too bad of a job for not having any real metal working tools, and it works just fine.

I'm getting ready to do the o-rings on the HPOP's of two vehicles, later to be followed by o-rings on the turbo, then to be followed by or-ings on the fuel pump, and the whole things topped off by new HPOP hoses and fittings into the heads.

I have to do this in stages just to manage costs.

 

Yes, I have a few HPOP wrenches that I have made up. I always keep one in the truck for good sake. If I took all the tools and parts out it would probably weigh a 1,000 pounds less!

 

Because i was not really sure if i needed the line or the fitting and time is short between now and the weekend when I will have a chance to fix the truck, I ordered both from clay. I figured if the line was good, I could replace the fitting and keep the line to go on my other truck that I travel all around in since I plan to sell the 2001. BTW< clay added the pump fitting to the website so it could be ordered if anyone needs it.

I figured i could then order the orings from diesel orings to rebuild whatever needed rebuilding for my truck. I also got the other truck an ebp tube as it is stopped up pretty good.

y'all have some great info in this thread on these fittings and orings to help me and many others.

 

I just found a "throw away" wrench that worked perfectly for a line tool. It is one of those wrenches that come with a product to assemble the product, it is a simple wrench punched out of a sheet of steel. I just had to sharpen the tips of the wrench a bit. I believe it is something like a 9/16 or 5/8 wrench. lol

 

I know that I have one or two of those as well, but just could not locate them in the mass of disorganized chaos I call my garage. I even tried to find one online to buy because I know they would only be a $3-$5 wrnech, but could not locate one there either. That's why I ended up cutting, drilling, and grinding on the piece of 1/8" flat bar I had to just make it myself. I wish I had more metalworking tools to make the job easier and end up with more of a professional looking tool, but the one I have works great.

 

hi guys' i have new HPOP lines in my truck, along with tool. do i need o rings for the pump fitting, or can i just put on the new lines? the lines are the new type from clay.

 

I have very organized tool boxes so I knew right where my collection of "throw away wrenches" was. I can check the exact size today just in case people want to know.

 

Sinson, you can put the new lines on, but I would suggest replacing the orings as well to have a completely new set of seals throughout the system. Otherwise, you have a new hose which will be good, but won't prevent your old orings from leaking and creating a repeat leak problem in the future. Remember, the orings are "normal wear items", and our trucks are getting enough age on them to where I personally believe it is a good move to change the orings altogether on a proactive basis, unless they have already been changed in the previous several years.

 

No, you are good to go, nothing else is needed to swap lines unless you want to be proactive.

 

ok, thanks. maybe i'll order o rings, the hose will be off any way. wonder if i already have them in that mechanics o ring kit from RR?

 

They should be in the combo kit that you ordered. Sounds like you are golden...

 

Thanks to the folks at Riffraff for getting my parts out the day I ordered them, the Valdez (as the guys at work call it) is back and running. So good, my wife ran off in it to the grocery store.

It ended up being the oring in the fitting that went bad. However, I replaced the line even though I had hoped to keep it for the other truck. The rubber dust shield on the old line was rotted to the point that it came apart when I disconnected the line. I could have used it but it would have made it a pain for someone else to disconnect.

I forgot to order two things when I made the order at riffraff- HPOP tool and inj harness. Had I had my die grinder wrenches at home, I probably could have used those but I ended up altering a door trim removal tool that worked perfectly. For the inj harness, I got one with the new style clip from the local parts house for $23. Its made by someone named Dorman but everything looked pretty good on it.

Between the harness and the line, the truck is already running much better. It still smokes a little at idle but I have pretty much decided that is just the way it is. I also did the GPR LED mod using an left over led from a CAT water in fuel sensor. They send an led in every sensor but the trucks are prewired for it.

Tomorrow the plan is to address the noses on both trucks and change them around to lay the plans for the 05 headlights on my 2000 model.

 

Reading a thread like this makes me wonder how concerned I should be about my HPOP lines failing me. How common is this? Are there any tell tale signs other than age?
And how hard of a job is it to switch out the lines?

 

Switching out the lines is easy....with the tool. It takes a little longer to do the fittings especially if you just rebuild them. The orings are supposed to be re-useable but they deteriorate with age. My leak came on all of a sudden. The thing with the fittings is that you have to clean the hole they screw into really well and then use loctite 680. I actually replaced the fitting last night and let it cure all night before I pulled the valve cover to do the harness and all. I found it easier to remove the icp sensor and the temp sensor on the back of the hpop reservoir to change it. I was concerned of hitting one of the sensors and damaging them.

 

Unlike the fittings on the HPOP, the oil rail fittings, plugs and ICP on the cylinder head do not require the 680 LocTite. It will not hurt if you use it, just not necessary on the heads.
