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

SOURCE: 1985 Ford F-150 Failed Smog - Gas tank failed pressure test.

Basically what he does is pressurizes the tank and all the lines up to the charcoal cannister.
Anywhere from the hose from the filler neck to the tank could be cracks or loose clamps.

The top of the tank has a seal for the fuel pump and rollover valves. These are rubber and could be leaking.

Under the hood you will see the charcoal cannister inbetween the radiator and engine on the passenger side. The hose could be unplugged or cracks. Or the cannister may of failed. The cannister is unseviceable
except for the valve thats on it if it has one.
You could spend a couple hours trying to find the problem especially if it on top of the tank.

What the shop will do is pressurize the tank again and with the smog machine sniffer they can stick it where you can't access to see if it can smell fumes.
Takes a shop 10 minutes to find the area if you want to know.

SOURCE: location of fuel pump on 1988 Ford F350 460 engine

there could be 2. one is in the tank,this one is there for sure. the other is in the frame rail ahead of the switching valve,if you have 2 tanks.Otherwise look for a cylinder with fuel lines and 2 wires.the fittings on inline fuel pump might take a special tool,they will look like a bell.that tool can be bought at parts store, should be under $15.

1985 ford f350 diesel will not allow the ignition to engage. Dash light says water in fuel. I put on a new fuel filter. Did not help. Can I bypass the sensor?


The Diesel engine doesn't have an ignition system. Also the dash light shouldn't cause it not to start? You said you changed the fuel filter right? After you started cranking it again did the lift pump fill the new filter up. I have had these before where the lift pumps go bad causing low lift pump pressure which causes the water in fuel light to be on. Did it die going down the road or did you shut it off and can't get it restarted.

There is a box on the passenger side, under the heater core. It's black and about 2 in by 2 in big. there is a white button on top. push the button down, noting how firm/loose it is. If it is loose, then the switch will need to be replaced. For reference it's called a inertia switch.
