HPOP
hey man I was wondering if you could look on your truck to see which lines go where, I took my off to service, but I can't remember where the lines go. or does it matter? From HPOP to heads, I think the closer outlet from the front of truck goes to passinger side, is that right?

same size, but someone else said it does not matter. it's not marked on the HPOP, left or right. but ****, I did not have a torque wrench, so I tighted the nut with the thick washer into the HPOP hard as I could, tried to start it to get remaining oil/fuel out of cylinders. (I put new o-rings on injectors). It cranked for the first time, then just spinning after that. so I checked the bolt with the thick washer and sure as ****, it came loose, guess I need torque wrench.

I also replaced the hpop oil galley end plug seals with the updated ones. It is rare that they leak but I feel as the years go by that you will see more and more of them leaking. My stock ones were very hard and brittle so I am glad I did. You could do the front 2 but if you decided to do these the back ones need the up pipes out. So just keep it in mind if you ever need to deal with your up pipes. Here is a photo of old design and the new 1 piece ones.

I've had both go at different times on my 01. Neither time was convenient. The 2nd one was a real hassle because it was just before a bridge, and I had a trailer on the back. At the least, if you have the older style braided stainless steel type, have a generic HP hydraulic oil line made up that will fit and put it behind the seat. Also, if you see your oil pressure gauge go to 0 suddenly, throw it into neutral quick. If you leave it in fear while it's rolling it will pump all your oil out, and then, even with a hose behind the seat, you're too low on oil to get it restarted.
