Ford Super Duty (1999-2016) :: Vacuum Elbow Cracked Badly?
Apr 15, 2017
I have a V-10 in my Y2K F-250. Under the throttle body there is an elbow on a vacuum line that is badly cracked. I went to parts store and bought a heater line that fit both ends (different sizes) but isnt the exact angle of the original. It fixed the hissing vacuum leak but now it is running pretty rough. Doesnt seem to be pinched but it's definitely different. The poor performance during acceleration wasnt a problem before but is very noticeable now. Could the line being different effect the performance?

Well I just bought a 2011F250 6.7 on Friday. The truck has 42000 miles when I picked it up and now has almost 42800 4 days later. I love the truck so far. But anyways its an early build so is there anything I need to look out for? I noticed today I pulled into a parking spot and went to back up and as soon as I put it in reverse the truck shook pretty bad. It did it a few times as I sat there and went from drive to reverse. Is this something that is normal?

So both the mirrors on my new truck are cracked. Driver side got hit, and the passenger side just doesn't respond, might just be a power thing. Anyways I'm wondering if there is any hassle to switch to a different style of superduty mirror? The 08 ones are really nice, if I can find a set for a decent price. Mine are just the basic ones, they look like half ton mirrors. I'm pretty sure they would just bolt in, and wiring really is no issue for me either. Just wondering if would encounter anything that might be an issue.

My '08 S.D. (5.4) has a cracked exhaust manifold, which I've heard is fairly common. Crappy Ford design. The local dealer has them in stock (imagine that, just like the 'non-bad' coil caps from some years ago, that they were instructed by Ford to keep at least 10 on stock at all times) for the passenger and driver's side. What are the part numbers?

I'm having a strange issue with my 2008 F350 6.4. I have only had this truck for about 2 months now. Every time it gets wet (from rain or a carwash), the 4x4 low light begins flashing, and the truck surges badly at low speeds. When I get above about 25 MPH, the light stops, and the truck runs normally. At the next stoplight, it happens all over again. After a couple days of dry time (?), the truck is back to normal (until it gets wet again). I have found a couple of old threads involving some similar symptoms, but they were never resolved on this forum (that I could find). I believe the transfer case selector motor has been replaced at some point, as it has a Dorman brand sticker on it. I wouldn't think Ford would use Dorman parts as original equipment.

I was just in the middle of doing the V Code leaf spring swap and noticed a broke part where the u-bolts sit and what looks to be attached to the trac bar. The piece is broken in half and I am not sure how this happened or when. The piece is welded to the axle.

I hit the trailer tow mirror on a column parking in my parking garage downtown...
The Orange Reflector on the integrated turn signal is cracked. The black housing has a little crack too, but is so minor I could just leave it.
I don't trust the parts man at the stealership...
Are the orange reflector and the black mirror housing all 1 piece? How to remove that outer housing to replace it?

my 2000 f550 master cylinder reservoir plastic is cracked from vibration and it would be good to know if it can be replaced separately than having to purchase a new complete unit.

How to diagnose a vacuum leak without a vacuum leak diagnostic tool.
My ESOF won't engage, AC/heat blowers default to defrost - classic symptoms. And while we can leave without AC/heat, we really need the ability to engage 4x4 low, especially as we get higher into the Andes and the roads unsmooth.

How and where to check? This probably has been covered a million times.

I have manual hubs on my truck. Can I pull those vacuum lines and plug the holes?

While rummaging in my garage a couple of days ago I stumbled upon a vintage Stewart Warner mechanical vacuum gauge. I would like to install it on my truck.
My question is: Where is a a good connection point for the vacuum line? Detailed direction/photo preferred as I am both Ford and V10 engine challenged.
Same question with respect to following gauges:
Volt
Oil Press
Water Temp....

I have recently developed a vacuum leak on my 2002 F-350 V-10 under the passenger side of the dash. It is only audible when I am accelerating moderately to heavily or when the truck downshifts going up a hill. None of the vehicles HVAC or ESOF functions seem to be affected by this leak from what I can tell, but it's rather annoying to listen to this loud sucking noise every time I hit the gas moderately hard such as climbing a hill or merging onto the freeway. I don't know how I could search for this leak since it only happens when I'm driving and accelerating and not at a stop. What might be going on or where I should begin my search?

Truck has been neglected for a while so this upgrade/repair I installed Powerstop brake rotor, caliper, bracket and pads. New Timkin wheel bearing, Moog U-Joints, and new inner/outer axle seals. Also replaced all the brake hoses and the remaining original rusty brake lines. About a month before I replaced the failed Auto/Manual vacuum operated locking hubs with Mile Marker units, which do not need the vacuum line, the drivers side was missing. and was letting water into the wheel bearing. So I decided to plug them and remove the vacuum lines from under the hood as well.
If there is interest I can get pictures of the vacuum lines, and what I changed under the hood. That was pretty self explanatory.
Could not find a google search for the thread size of the vacuum nipple in the knuckle. It is a 3/8"-24 fine thread.

I don't have any leaks at the moment, but after inspecting my vacuum lines they're starting to look brittle and I want to replace them proactively. Is there a kit to do this or should I just cut a section off and take it in to an auto parts store to match the size, and buy it by the foot?

So my auto locking hubs have not been working for a couple years and I have just been locking them manually as needed. But now I have a boat and I like putting the truck in 4x4 at the landings just for added safety. It's difficult to manually put the truck in and out of 4x4 for just a few minutes when I know I have auto hubs. Plus I recently got aftermarket rims and they cover the manual locks, which can be accessed with a screw driver, but again, tough.
So today I bought the vacuum solenoid valve, whatever its called, and installed it, and they work! But the vacuum pump will not shut off while the 4x4 is engaged. The auto hubs work, my a/c controls work, everything works fine, the only symptom is the pump not shutting off. My a/c stays right where I put it, it doesn't go into defrost or anything, not even for a second, like it used to when my solenoid first started failing. Is the pump running normal? Or is there a leak on the other side of that solenoid? Should I even worry about it if everything else is working?

When I put my 06 f350 in 4x4 my ac defaults to defrost. I assume this means a vacuum leak. My question is, is the white tube supposed to be open for air intake or plugged off with something?

Having trouble with vacuum on my '06 CCLB V10. I only lose vacuum while towing, not sure why. Lines all seem like they're fine. I have no issues while unloaded. What could be causing this?

I have a 2004 F-350 diesel. My vent selector is always on defrost so I suspected a broken hose but traced all out and all seem to be fine. I disconnected the line coming from the pump to the tank and no vacuum. The pump doesn't seem to be running but it's hard to tell with the engine noise and vibration. What tells the pump to run and how can I bench check it?

Its hot in St. Louis and my windshield sure is staying cold (ac blows from defrost vents only).
1999 Ford F350 7.3 diesel 4x4 (4x4 lever on the floor). About a month ago, the ac starts blowing out of the defrost vents only. I assumed it was a vacuum issue.
Lines looked good; very plyable still. Canister looked fine. The vacuum pump on the pass fender well smelled burnt, so I replaced it. Got the new pump in and it didn't work. Checked the fuse panel and found two blown fuses, replaced them and the pump worked.
Here's my issues: if AC max is used, the vacuum pump stops working and air blows through defrost only . If the dash switch is in the off position and then turned back on, air blows through defrost vents again and vacuum pump will not work.
Is there a solenoid or switch to this vacuum pump that I'm not seeing?
