I want to make my 99 f250 reliable to take Ca to Tx and back. Belts, hoses, w/pump, rad. - all good. I recall something on the hp pump should be replaced on our older 7.3's. Any suggestions of items I can replace in my garage now instead of on the highway? 165 k miles and 17 years old. Thanks

165k isnt alot of miles. Not on a 7.3 anyways. If all maintenance is up to date I would just make sure I have normal spares/extras and tools and go for it.

What wolf just said.
Get a diesel orings emergency glove box oring kit. An extra cps. Enough tools to handle a repair if needed and roll! Mine has 330k+ and I wouldn't hesitate to drive it cross country.

Thanks. I always carry too many tools on the road, a spare serp. belt and a spare CPS. I love my old f250 cab, plan to keep it another 5-10 years, would like to replace o rings elect to avoid break down on the road. Anything, o-ring replacement, spare sensors, etc. I can replace easily now- items highly likely to fail in the next 100k. I'm going to keep the truck- money spent on it will add confidence going on the road, and is a lot cheaper than a newer, head bolt stretching diesel. Thanks

That oring kit I mentioned has basically every oring that could possibly need replacing. If you are just wanting to go through and freshen it all up get the kit and have at it!

The hpop things you are speaking of are the high pressure oil lines that go from the pump to the heads. Lots of trucks out there with 2-300 K on the original lines, others have had them blow out much sooner. I chose to replace mine at 150K. The new ones are updated from Ford. I also got all four STC fittings new instead of rebuilding my old ones. The ones on the pump take a while as you need to drain the hpop res. and clean the threads really well then dry and apply special lock tite. I got the threads spotless and waited 24 hours for everything to dry out then followed the instructions to the T. With the new fittings and the red ring printed on the updated lines to verify full insertation, assembly was a breeze, they just snapped right in with little effort. Heard horror stories about guys thinking theirs were fully snapped in only to have one blow out and spew oil everywhere. If you choose to keep your old fittings at least get the oring kits for them and clean all the dirt out so they will snap in easily.

With regular fuel, oil, and trans service, you should be good to go. About the only spare item I carry with me is a CPS and the tools to replace it. Have faith in the ole 7.3L!
