Ford 6.0L Power Stroke Diesel :: Low Fuel Pressure - Hissing / Air Noise At The Upper Filter Bowl
I have an isspro gauge and did the blue spring about 5 years ago. Since then my fuel pressure is in the 65psi range.
Last week it dropped to 50-55 normal driving and I figured the HFCM was on it's way out (195,000 miles). Replaced the HFCM and the pressure was a bit higher, but not back to it's usual range. Then pulling the boat home from the lake a couple days ago, I saw it at 45psi. On a couple hills it went as low as 40 psi, so I was getting gripped...coasting downhill it only went back up to 50 psi and no higher. Got 'er home and currently not driving it.
In garage with Key On Engine Off, during injector buzz, I can hear a hissing/air noise at the upper filter bowl. Also, the bowl drains empty once the pump cuts off and the sound of air stops too.
I am hoping it's a regulator issue, but I don't know if they are known to wear out or go bad, or if something else in the upper filter housing went bad. So I ordered a new upper fuel filter housing which also has the oil filter tower attached and I'm assuming that these new units would come with the blue spring upgrade already done.
I can check for codes tomorrow when I bring my computer home from work, so I haven't checked for codes yet. I pick up the new filter housing tomorrow and will periodically check back here during the day tomorrow.
Also, while I'm at it: the new HFCM doesn't have the heater. Can I just leave the old connector from the harness un-connected to anything?
Ford 6.0L Power Stroke Diesel :: Slow Fuel Drip Off The Housing For Fuel Filter On The Engine
I have a very slow fuel drip off the housing for the fuel filter on the engine. Can't see where it's coming from. It started sometime after I changed the filter a couple of months ago.

I've got a leak that appears to be coming from the secondary fuel filter housing (the one in the engine compartment)... It's not coming from the filter, but from the side, where there are 4 allen bolts that attach a fitting to the side of the housing...Can I change out the gasket for that piece? I've already tightened the bolts, but the leak persists.

Ford 6.0L Power Stroke Diesel :: Top Of Engine Fuel Filter Part Number?
With an AD2 and no HFCM, need to have a part number for just the top of engine filter? All I can find (Motorcraft, AMSOIL, Racor) are the dual filter kits.

When I fuel up and open the cap on the filler neck I always hear a hiss. Never could figure if it was pressure or vacuum. Today, after changing oil, I opened my fuel filter bleeder to check for water and it just started slurping and gurgling with no diesel coming out. I lowered the truck, removed the fuel tank filler cap and heard the hiss. Raised back up and opened the filter bleeder and diesel came out. I now know the hiss is a vacuum. Is this normal? If this tank is vented I have a problem somewhere.

My truck is running fine but it sounds like there is an air leak on the drivers side of the truck. When it first happened I was passing a car and it sounded like a vacuum hose come loose. It made a loud hissing sound. Now I have come to the conclusion it must be associated with the turbo. I don't hear the hiss unless I get into the truck and the turbo starts making boost. The more boost is made the louder the hissing sound is.

I have a 2003 F350 with a 6.0. I just finished replacing my HPOP (Adrenaline Pump from Diesel Site) and fired the truck up and its making a hissing sound from the rear of the motor back by the turbo almost sounds like a tire leaking and its loud enough to hear over the engine. The truck is running and idling good but it doesn't seem to be quite 100% when I step on it.

Well I finally had time to change out my composite oil pan to the metal one. Nothing was wrong with the old one but Ive seen the composite pans get hit by a rock and crack so I decide to get the metal one. It didnt take long once I had the oil drained and its very easy to get to. Once i had the old pan off I did find two piece of sludge stuck to the oil pickup screen, they had a sliver of aluminum in them. My oil reports have been coming back with high aluminum content so I am not really sure what to think being my motor had 33k miles on it now.
I also changed out the fuel filter and when I dropped the frame mounted filter I found about a teaspoon of rust in it. I'm not one to run my truck down to E but I admit I did so twice since the last filter change. Since I found the fuel filter kit for 60 buck(ford dealer wanted $140) I think I will move my fuel filter changes to 10k miles instead of 15k. Last but not least I also added SPE 6.7 Full Lock Diff Kit which allows the locked rear end to stay engaged past 20 mph. It was a simple 10 min installation with just a few wires and easy directions to follow

Ford 6.7L Power Stroke Diesel :: Oil And Fuel Filter Warning
While driving from SD to Chicago today 2 warnings popped up at the same time saying to change the oil and fuel filters. Had both done 2500 miles ago. Am I right that the Dealer just didn't reset these? I thought these were measured by miles and driving habits.

I was going to change the fuel filter on my truck yesterday, but couldn't figure out how the guard comes off. It has a bolt but it also has a rivet in it and looks like its all one piece so Id have to drill the rivet to remove. I tried to just spin the housing off.
View 8 RepliesFord 6.7L Power Stroke Diesel :: Fuel Filter Metal Debris
While I was changing the oil yesterday, I also changed the fuel filters. The primary filter had some debris that was confirmed by a magnet to be metal. I have seen a little bit of this all three times I have changed the filters. The filter itself is very clean, but there remains a small amount of metal slightly more coarse than filings.
I don't really have any concerns that it could be coming from the HPFP because that is after the secondary filter and would not be returned to the tank. Also anything from the HPFP would have fouled several injectors by now. I don't even think there is any iron in the pump.
I guess it could be useful to put a magnet in the water separator reservoir, but I don't even know what good that would do since the debris is large enough that it is being caught by the filter and of course the secondary filter is even less microns. It would just be nice to know where in the world this stuff comes from.
Ford 6.7L Power Stroke Diesel :: 2014 - Changing Fuel Filter?
Noticed change in power after changing the fuel filters on 6.7 .... Seems like it has a fuel restriction at times maybe even air somewhere in the line. Thought I felt the truck hesitate after hitting the gas and Cavitating when I hit the gas petal. Both new filters are motorcraft parts. I did follow the procedure after installing filters by turning the key on 6 times waiting 30 seconds in between. Could it be a problem with the fuel pump. I should say I didn't have this until I changed the primary filter.

Changed my filters and this was in the bottom of the filter housing. I looked on the pleats and down in the center didn't find anything. Went to two Ford diesel techs one said is was the hpfp and should do the the whole fuel system. The other said if the hpfp was coming apart the shaving would not be in the bottom of bowl and to check the filter again in 5k miles. No check engine light, drives great, no other problems.

Replaced both fuel filters same as usual. Cranked right up and I let her run while I put up the tools and look for leaks. Notice it started running rough, so I jumped in and started to back out of carport and it went dead. Ran battery down and it won't hit a lick. Replacement (racor) filter same as last few changes. Running just fine before change so it has to be something simple, but what?

Ford 6.7L Power Stroke Diesel :: Lower Fuel Filter Housing Broke
This past week my wife and I took a short trip and returned on a gravel road. I went to start my truck the next morning and there was a puddle of diesel fuel on the driveway. When I looked under it, I noticed that the tip of the fuel filter housing is gone and is leaking slowly from there. I called the dealer and they would not fix it on warranty, the truck has 20k on it. The service man said he would not turn this into ford. I've had the similar problems with this particular dealer. It's obvious that a protective cover is needed for this. I kept the part and am thinking of sending it to ford.
