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

Hello freefallcrus
The fuel pump relay for the 2003 f350, is an integral part of the central junction block(fuse box) located under the left side of the dash. So in order to replace the relay, you would have to replace the junction block. Hope this is helpful.

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.

1988 F350 stopped running today. duel tanks both full. 73,000 miles on a 460 efi. Can it be in tank fuel pumps or is there a relay or fuse or ?


Do you hear the pumps run when key is in the run position? There should be a relay for the fuel pumps. However check and see if you have spark, have your ignition module tested, most parts stores can test them. Also check the ignition switch and make sure it is operating properly and not needing to be replaced.

I have a 1988 camper it's on a Ford F350 chasse with a 460 ci. engine. Has one gas tank with a low pressure pump in it and a high pressure pump on the frame rail. The truck runs for an hour and dies. at...


The catalytic converter may be fried. Very poor design of the restricted exaust ports.
And the fuel pumps are junk straight from the box. Around 94 Ford had to change the design of the fuel pumps.
I am not a mechanic but had the same issues.
I removed the catalytic converter and get the inspection done by a freind.
Your alternative is to change the entire exaust system to say a "Banks". Which is about $3000 for the paRTS.

1988 Ford F350 won't start


U will need to get the fuel pressure checked to confirm it is or isn't the problem, there is no substitute for proper testing work if u want to repair the truck in a min of time and a min of money spent on un-needed parts.

1988 Ford F350 engine turns but wont start


I had a similar problem. My truck would start fine until it sat after running a while and I shut it off for ten minutes or so.The engine heat heat would rise to the deisel fuel injection pump and the truck would whirl over when I tried to start it, but it would not fire. There is a spring in the fuel shutoff on the injection pump that expands with heat and, as it gets older, sticks so that the solenoid doesn't open. I found that a small amount of cool water poured on the pump would cool it enough to start.
