Do I have to remove my fuel filter and bowl to attempt a repair on my HPOP leak?

The leak drains into the first valley of the block. This is after a cleaning and about 300 miles driving. I thought it may be the IPR but, it's looking pretty dry:
Some more pics .....
The HPOP line fittings are dry too. Where else do there the HPOP's tend to dribble a leak of oil from?
Ford 7.3L Power Stroke (1999-2003) :: Small Leak Under HPOP Driver Side Near The IPR
After cleaning entire valley on my 2001 f350 with 7.3 I have found what appears to be a small leak under the hpop drivers near the IPR. HPOP lines are clean and dry. Possible for IPR to leak at 120k miles and what will need to be done to fix.

Have another oil leak, just finished the pan flange gasket last weekend, made it 150 miles, now a new leak.
Took the spider out and everything on top, cleaned the valley up good, the fired the truck. HPO lines are good, but have a drip off the back and bottom of the HPOP, when I reach under it from the back, its right below the large 2 inch circle.
What this might be? was thinking possible orings somewhere under there where it seats, but its been 6 years since I replaced all the orings, don't remember exact layouts.
Ford 7.3L Power Stroke (1999-2003) :: HPOP Hose Leak At Cylinder Head
I have an oil leak where the HPOP hose attaches to the cylinder head. I have the removal tool for the hose. I assume I need a new fitting. What's the torque spec for this fitting, and any additional tips I need for doing this repair?

I'm having Hard start when Hot problems, starts fine when cold. It takes a couple of minutes of cranking for ICP numbers to hit 500.
So far I've replaced:
ICP sensor
IPR
Injector O-rings.
Still didn't fix the problem.
I also washed out the engine, and put uv dye in the oil, let it run, to find any external leaks, but I found nothing. I don't thing it's the HPOP, because it's able to sustain high ICP numbers when I hold down the throttle.
My next step was to remove the HPOP and replace all it's o-rings, but I assume since I don't see any leaks, the o-rings aren't the problem. Is there anything else to check, that could be causing low crank ICP numbers when hot?
Ford 7.3L Power Stroke (1999-2003) :: Oil Leak Is Coming From Fitting Connected To Lower Part Of HPOP
Last couple of days I've been chasing a small oil leak. Finally figured out it's coming from one of the hoses connected to the lower part of the hpop (hpop hose). Leak is coming from the fitting connected to the lower part of hpop. Do I need to replace the whole hose and fitting? Just the fitting? is there a replaceable washer or oring?

I tried a steel with rubber insert washer, but it still leaks. I might have overtightened or something. It seemed good for a while. Who has a solution for this leak?

So I tried to replace my thermostat and housing and the housing bolt snapped off. Ok so I tried to extract that bolt off and the extractor bolt snapped off inside. I am guessing it might just be easiest to replace the water pump now? I am pretty much at the end of my mechanical rope which is short anyhow.
View 6 RepliesFord 7.3L Power Stroke (1999-2003) :: Leak From The Rear At Drain Valve
After checking my fuel bowl today for contaminants, I put the lid back on and then noticed a leak from the rear at drain valve. I know, I already ordered the orings. It was doing one drip about every three seconds with the truck running. However, I turned the yellow thing a couple times and the leak stopped. Not leaking right now. Maybe it wasn't shut from previous owner.
Second question.....After stopping leak and after routing my fuel drain hose, I decided to give it a try. No luck. Nothing out or drain. Based on my first fuel filter change, it may be clogged up. So, do I run wire from the bottom up? Or do I run wire from top (bowl) down? Just so you know, sucked the bowl dry with a vacuum device before I reinstalled the filter.
Ford 6.0L Power Stroke Diesel :: 2003 - Weak HPOP / High Pressure Oil Leak?
My 03' 6.0l hpop only makes about 1700 psi at wot, at hot idle the ipr is 25.1 and the icp is about 580. It runs pretty good but it seems the crank time to start is getting a little longer sometimes, other times it fires right up. It makes no difference if its hot or cold. Do pumps get weak or do you think I have a leak?....

So the water pump on my early 99 (158k miles) is starting to leak just sitting in the driveway, did a little research last night and read a few write ups. Just wondering if any tips or tricks I could use to make this go easier. Also any list of parts I should replace and/or might need. I read on one write up about replacing it with an Airtex water pump and was wondering about what people thought of those, I would rather fix it right then just go with the cheapest parts. Possibly there are better brand water pumps out there?

I did the extended seal kit and non-serviceable plug on my HPOP and now the CEL is on. It is throwing the below codes. The truck in all reality runs fine and even a little better on a cold start than before resealing, just the CEL is on.
P1280
P1209
P1282
P1212
P1211
I cleaned the IPR when it was out when I put new seals on it but could it go bad by just taking it apart? The ICP and IPR are definitely plugged in. The truck is all stock, no chips.
Ford 7.3L Power Stroke (1999-2003) :: HPOP Dying - Fix?
I started "Hard Start at Operating Temperature" you can probably tell that 300k has done a number on my HPOP. I'm wondering what to do... do I buy a new pump from ford? Buy from ebay? Or is there a good pump rebuilder in the Portland metro area? I've heard they are almost impossible to rebuild.
View 6 RepliesFord 7.3L Power Stroke (1999-2003) :: Low On Power / Injectors HPOP Or Tune?
So I have a 2002 7.3 Excursion and I think it is low on power. ICP is falling on its face when on a 60 or 80 HP tune. I have some boost leaks at the plenums and will work on that but that shouldn't cause my ICP to tank at full throttle. Following are some numbers I pulled with WOT runs up a 6% grade.
16PSI BOOST
EXHAUST PRESSURE 40
ICP 1900
80%IPRDC
this is with the 60 or 80HP tune on my DP-tuner. If I ease into the throttle I get
2700 ICP with
45%IPRDC
but if I stomp on the throttle it stumbles and ICP tanks.
Running the stock tune I can maintain
2700ICP at
40-45%IPRDC
Is this my HPOP being weak, or worn out injectors, to much of a tune or a combo of all three?
Ford 7.3L Power Stroke (1999-2003) :: No Start After HPOP Reseal
Pulled the HPOP reseal an oring that was leaking oil. Feel confident that I made sure the check ball stayed in place. Torqued the bolt to 96 ft lbs. Have fuel in the bowl.
We have cycled the starter about 20 times for 15 to 20 seconds. Batteries are charged.
Here is what the AE scan tool is saying after a few seconds of cranking:
ICP -160
IPR - 0.43
Duty - 63.67
Do I need to get a different reading/test.
I have read about stuck open IPR valve giving the low pressure problem, but the truck was running prior to pulling the HPOP.
Lets say I left out the check ball. Would the scan tool show 0 pressure? (Trying to rule out the check ball)
How about if I didn't get the spring seated in the high pressure oil fitting and instead it is hung on the threads and is compressed inside the HPOP. Could that be the case?
Not for sure it makes a difference, but the truck did fire off once on Ether for second.

View 14 RepliesFord 7.3L Power Stroke (1999-2003) :: Replaced HPOP Now No Start
This started out as a turbo pedestal O-ring change (leak down the back of the engine). Since I was going to take everything out to do that I figured I'd reseal the fuel bowl and hpop. Wound up replacing the up-pipes as well. Went ahead and changed the ICP and CPS. The truck started rather easy as I've heard its hard to get the air out. I drove it about ten minutes and then noticed it was leaking oil so I went back to check it. I found that it was leaking from one of the output fittings on the hpop as I guess when I tightened it back up after putting on new orings I damaged the pump by over tightening.
The oring and fitting were fine it was on the pump threads I guess. Anyway trucks got 280k miles so I just bought a new hpop from the stealership. Went home and installed it and the truck won't start. Pulled ICP out and cranked no oil coming out. The only other thing would be ipr (I cleaned with brake cleaner and air tip before putting in the new pump) so just to know for sure I bought a new IPR from the stealership and still NO Start. I didn't fool with anything else don't know what it could be. I checked the bolt in the front cover (tight), got to be a BAD (new) pump right.
