Ford 7.3L Power Stroke (1999-2003) :: High Pressure Power Steering Hose
My high pressure power steering hose just blew at the "B" nut at the pump. Meaning, the fitting is still in the pump but the line is out. Do I need to replace the whole line or is there a retainer I can swap out?

I've found everything there is to know about disconnecting the high pressure oil STC line from the oil rail on the early 6.0's, but I can't find anything about reconnecting them. Do you simply press it back on? Should there be an audible "click"?

I have an 03 Accent. The all metal high pressure power steering line had a leak. So I bought a new one for around 70 dollars from Hyundai. This part has a curved shape and fits around the radiator. The old one was difficult to get off, but the new one is proving impossible to get on. I cant get it into place.

Ever since i bought my truck i have had a bad power steering whine. Replaced the pump and its still there. I got the truck in 2006 and think i replaced the pump in 08 maybe. Anyway I've purged, bleed, changed the fluid. Pulled a vacuum on it and still no luck. So I've just dealt with it for 11 years.
Well i can remember reading something somewhere about ford up-dating or redesigning one of the power steering lines that was causing this noise.
My father inlaw just bought a 02 and its so pleasant not to hear that when riding in his truck. It made me want to investigate the matter. SO if its as simple as a updated line I'm buying one asap. He got rid of his Chevy because of the reliability I've gotten out of mine.
Ford Ranger / B-Series :: Power Steering Leak / Sensor On High Pressure Line?
I think I've tracked my power steering leak to some type of sensor on the pressure line, close to where it connects to the steering box:
I assume this is a pressure sensor? I got no CEL or anything like that when the fluid had leaked down to the level that the pump started whining pretty badly though. As far as I can tell by looking at pictures, the parts store replacement pressure lines do not have this sensor, or any provision to connect a sensor to it: Advance Auto Parts: Power Steering Pressure Hose by Powercraft - Part 71878
I may just put a replacement line on there and leave the sensor plug hanging and see what happens...

I blew a power steering cooler line yesterday and lost a bit of fluid. Removed and replaced the line, consequently losing most of the fluid in the system (during line replacement). Re-filled the system and now i have great power steering when driving but none at idle. If I bring my RPMs up about 150-200. I get it back in full force. Could my PS pump be on the way out or might this just be air in the system?

I've been watching fluid build up on what I think is the hi-pressure line on the hydroboost. It appears to be originating at the coupling in the line because it is dry back at the unit.
Is there an o-ring or nylon washer in this fitting?
Can it be tightened?
Does the o-ring or washer need to be replaced?
Is it a sign of something else, like a build up of pressure in the line that is too high?
I currently have zero problems or noise coming from the steering or brake system.

View 7 RepliesFord 7.3L Power Stroke (1999-2003) :: High LPOP Pressure - 75 PSI With A Warm Engine
I noticed this evening that my low pressure oil pressure was much higher than normal. I have a LPOP gauge that typically reads 12 psi or so at idle This evening I was seeing 75psi with a warm engine. Every little acceleration pegged the gauge over 100psi.
The factory non-functioning gauge says that everything is normal.
I am about due for an oil change. I was thinking that I would change the oil and filter as soon as possible and temporarily plumb in my mechanical gauge to see if the high pressure reading is real or not. I replaced the stock LPOP about 3 years ago with a melling and everything has been golden up until now.

View 2 RepliesFord 7.3L Power Stroke (1999-2003) :: Testing High Pressure Oil System / Air Coming Out Of CCV
'99 7.3, 258k miles, looses oil fast, oil found in coolant (though not a lot) and the fuel bowl is full of oil.
I re-ringed the oil cooler. Most of the coolant and oil is drained. The HPOP holds its oil level and does not leak down.
Someone shared the below test. Though it says #4 ORB, the actual thread on my IPR is #8. I removed the IPR and threaded in the #8ORB to air hose adapter. I regulated the pressure to 20 psi. The air is rushing out of the CCV.
I suspect I am missing something in the below test and that I'm pushing air back through the low pressure oil pump and into the crank case.
The test shared with me elsewhere:
Apparently someone named "Cody" on the forum did a test and it was labeled that way.
AIR TESTING THE HPO SYSTEM:
7.3L Powerstroke engines may experience hard start and or no start issues. In some cases the no-start issue may occur only with the engine hot. If the observed ICP pressure during cranking is less than the required 500 PSI, then the problem is in the high pressure oil system.
One of the first checks that should be made is to remove the plug from the top of the high pressure oil reservoir (in front of the fuel filter) to observe if the reservoir is full. If the oil is standing within an inch of the top of the reservoir, then the problem is in the high pressure oil system and could be caused by one of three things:
- The high pressure oil pump itself
- The IPR Valve
- A high pressure oil leak
Tools: Adaptor ORB #4, Air Compressor capable of maintaining 90-100 psig, Air Line Adaptors which will allow connection to the #4 OBR , IPR Test Harness, Grease Gun Whip or any whip with a .0625" NPT.
Remove the IPR valve and insert the ORB #4 Adaptor. Attach Shop Air and pressurize the system. Wait for approximately 30 - 60 Seconds while the air travels throughout the HPO System. Listen for air escaping through the Oil Fill Tube (cap removed).
External high pressure oil leaks would have, of course, been obvious. The primary concern is internal leaks under the valve cover(s). These could include leaking injector O-rings, or leaking injectors. Listen for any air escaping under the valve covers and correct if present.
If the center injector O-ring has failed, high pressure oil may be forced into the fuel system. Remove the fuel filter cap and observe for air bubbles in the fuel. If necessary, individual fuel lines running from the fuel filter assembly to the cylinder heads can be disconnected in order to isolate the problem to which side it is occurring.
2. 7.3L: If no air leaks are observed, the next step is to isolate whether the problem is with the IPR or the high pressure oil pump. Remove the IDM fuse or unplug the IDM or injector connectors at the valve covers to prevent starting.
3. If this test does not assist in diagnosing the issue, remove both valve covers and witness oil from the deflectors as being uniform, look closely at the injector base for any sign of air or oil escaping during test. This is an indication of a loose injector or O-Ring failure.
The same can be done at the ICP Ports (Oil Rail) on either side to determine leaking O-Rings in that Bank.

Next mods are for the fuel rail cross over and the high pressure oil cross over. I see the unused ports will come in handy.
Fuel delivery? any specialty mods to run the fuel lines? I see it's a #4 ORB fitting. Anyone ever use a "T" or a splitter off the fuel bowl to have a quad line set up?

View 1 RepliesFord 7.3L Power Stroke (1999-2003) :: Low Power - Fuel Pressure?
Low power on my 2003 7.3 F350. The truck runs fine but I can tell it is low on power (seat of the pants). I figured it to be fuel related so changed fuel filter and oil with no change. When that didn't work I installed a fuel guage and this what I found. Key on no start fuel pressure 45 psi. Start truck the pressure will get up to 61psi. Under a load it will drop down to the low 30s. I have dropped the tank mixing chamber screens clean and so was the tank. Changed fuel pump and now under a load it drops to the high 30s. Does this sound like the fuel pressure regulator is leaking by and causing low pressure under a load? Truck is stock besides superchips 1705 programer.

So my transmission drove perfectly fine I just wanted to put an upgraded torque converter in especially after driving a customers' truck with a low stall converter. I know their not like for racing or anything but it's a work Truck with some mods to the motor nothing crazy. So I went ahead and bought a low stall triple disk converter and I drove around the block fine and went to go on the freeway and got into fourth but lost it as I hit 75 (was not flooring by any means and had it in the stock tune) now it will not go past second gear. Once it did this the o/d off light started to flash and I decided to do a stall test.went to 1800 in a Second. Suppose to stall around 1200-1300.

Ford 7.3L Power Stroke (1999-2003) :: Fuel Pump Fuse Blown
So the other day my 20amp maxi fuse for my fuel pump decided to blow, put a new one in & everything has been going good since. Is it just a fluke or is this an indication my pump is going out? I inspected wires off the pump & connections for corrosion & that's good, fuel filter is also new about 2 months ago & I always run #1 diesel with a little additive in the winter.

So, I have a 1995 Jeep Grand Cherokee (Orvis edition) with about 270,000 miles. It still runs great and has been really useful in the snow this winter. A couple days ago the power steering pressure hose blew. My mechanic wants to replace it, but I can get a replacement hose locally. Is there any reason I shouldn't just do this myself. Do I need to worry about the fluid sprayed around the engine? The serpentine belt is only a few months old and squeaked only a little on the three mile drive to get it home.
