simple : obtain replacement pump from parts provider (no used stuff)
Now help me out here: thats the year they were bolted to the pass side front of engine
and not inside the tank right? (better go look to see for sure)
using a tube wrench unscrew the fuel lines (i use large wire nuts to temp block off fuel leakage)
with a 12 mm wrench undo the two side bolts holding the pump to block
wiggle pump it should come straight off
clean mounting place on block with solvent let dry
silicone back (or use gasket that comes with pump ) of pump
apply pump to block (depending on where crank stopped you may have some tension on arm you will have to overcome to get flange to meet block )
use locktite (blue)or simmiliar thread lock on bolts retighten firmly but not hang up the dog tight
use light grease or vasolene on tube connections don't try to tighten dry
Now the fun part your diesel now has air in the fuel system
there are two ways to remove this ( hard and harder)
your choice here are both methods
loosten the fuel supply line for #8 injector ( I did not say remove) 1 full turn ought to be enough
crank engine 30 seconds only
wait 5 minutes for starter to cool down
crank engine 30 sec again
did it start but runs rough while it's still running tighten #8 injector (caution fuel under high pressure)
engine smooth out good your lucky
engine did not start yet
wait 5 minutes
crank engine 30 sec again
if so tighten #8 injector up
Now here's something I've done to my diesel to make this much less a hasstle
trace fuel line as it comes up from pump
obtain a small low pressure electric fuel pump and a two short pieces of fuel line
and a few clamps
use tube cutter and cut fuel line just before it bends to go in filter
slide tube and clamps over pipe (both sides)
insert pump observe flow arrrow towards filter
the wires of pump can be stretched over to #1 battery terminals
now any time you change a filter or open your fuel system for any reason
all you need do is connect pump to battery
open sharader valve on top of filter for a few min
and start truck as normal
then disconnect wires and stow away for another day
