PMD, lift pump, or OPS are the 3 cheaper things to check, may want to do them anyway if they are pretty old.
Really? Let some diesel mechanics chime in here. You make it sound so easy Woof!:wings:
Some good sugestions here guys, but I got a couple of questiions.
1 How hard is it to change the pump? Do you have to remove the intake manifold to get at the pump? Thts what I have heard as I belive its mounted under the intake. I heard you need special wrenches.
2 What if any change in performance would I feel by changing to a manual pump as opposed to a stock pump with pmd.
3 Does it really py when I am qouted $1600 for high quality pump and pmd with a $2500 to $2800 install at a reputable shop with a garantee.
I would ove to go high budget but honestly folks, the truck might need a year of parking time before I make a decision.:smiley_drive:
Decisions, decisions. If you don't need the truck on the road ASAP, throw it in corner of the yard and get back to it later. Take time to think about the different roads to take. One thing I've from experience is that the cheap/easy road usually ends up costing more in the long run and biting you in the ******** later.
To get the pump off, you need to disconnect all the electrical plugs that's in the way, remove intake manifold, loosen all the fuel lines from rear of pump(mark them so you can put them back on in the right order later), remove oil fill elbow pipe thing on front of timing cover, rotate crank to get to the three bolts on the timing gear, then remove three mounting bolts in the valley holding the pump to the engine. I believe all you need in basic mechanics tools, nothing fancy. Only advantage I can see with running a manual pump is simplicity and not having to worry about that stupid PMD thing. I'm sure with any 6.5L you can run either manual or electronic fuel delivery system. To each his own...

Its not an overly hard job to do but it does take some time and some skill. The passenger side fuel lines can be a pain because of the way to turbo is mounted and some of the lines on the injection pump are a tight fit to get too, I have a few modified wrenches to get to these lines off easier. Its a hard call as to whether or not to pay someone to install it or do try it yourself. I have know people that have done repairs similar to this by themselves with good results and I've had a lot of trucks towed in after something went wrong and the owner wasn't sure what to do at that point in time.
The only advantage of going to a mechanical pump is the reliability factor, no performance gains. A pump shop can turn up the fuel on a mechanical pump if so desired but lets face it, its a 6.5, if your after hp you picked the wrong engine lol

Funny thing is that I have never seen a single 6.5 pulled off the side of the road with their hood open while driving over our numerous high canyon passes, see plenty of the other diesels though and just wave as I drive past. I have towed tandem/double trailers behind our lowly 6.5 with our Jeep on a flatbed and the pop up hooked to the back of that and it towed them happily, they were not designed to tow the heavy loads like our newer diesels but got good mpg and are very reliable once you relocate the PMD and replace the exhaust.

I usually removed the IP and injector lines as one unit, disconnecting the injector lines from the injectors and capping the injectors to keep trash from getting in there. I did a similar pump install with an International 6.9 in my old Ford 4x4.
Probably easier if you pull the lines and pump together. I did mine in a day. It wasn't fun. But it wasn't worth thousands of dollars to pay someone else to do it.
I'd stick with exactly what you have. My PMD never gave me an issue, but my truck never had the plastic over over the engine either, which probably helped...
