IF YOU GOT A MECHANICAL TRANSFER PUMP YOU NEED A FLARE NUT WRENCH TO LOOSEN THE THREADED FUEL LINES.LOOSEN THE MECHANICAL TRANSFER PUMP BOLTS ONE OR TWO TURNS.MOVE THE PUMP BY HAND TO BREAK THE GASKET SEAL.USING A REMOTE STARTER SWITCH OPERATE STARTER TO ROTATE THE CRANKSHAFT IN SHORT BURSTS UNTIL THE FUEL PUMP CAM IS AT IT LOWEST POSITION.WARNING STAY CLEAR OF THE FAN AND DRIVEBELTS.DISCONNECT THE FUEL LINES FROM THE FUEL PUMP.REMOVE THE FUEL PUMP MOUNTING BOLTS AND REMOVE THE PUMP.THE ELECTRIC TRANSFER PUMP.TURN OFF RADIO FIRST THEN DISCONNECT THE NEGATIVE BATTERY CABLES. DETACH WIRES FROM THE PUMP.DISCONNECT THE FUEL INLET AND OUTLET LINES FROM THE PUMP AND PLUG THE LINES TO PREVENT CONTAMINATION AND LEAKAGE.LOOSEN PUMP MOUNTING BRACKET AND REMOVE THE PUMP.THE ELECTRIC TRANSFER PUMP LOCATED ON THE ENGINE MOUNT NEXT TO STARTER.THE MECHANICAL TRANSFER PUMP LOCATION IS ON THE RIGHT PASSENGERS SIDE OF THE ENGINE LOW AND NEAR THE FRONT.
SOURCE: Need to replace the original fuel pump in a ford f350
Not too much of a problem really.....you want to have a pretty empty tank. Your pump is in the gas tank. Best way to do it is have a digital camera in hand and take plenty of photos . Easy part is dropping the tank, unstrapping it, undo the wires and hose/tubing....remember to replace the gasket.
It's easy, take your time and you can do it. No special tools required.
SOURCE: replace fuel pump on 03 Ford F350 diesel
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
start yet
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
deburr edges
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
