Ford Super Duty (1999-2016) :: 2003 F250 V10 - Fuel Smell / Gas Tank Vent Leak

New to me 2003 F250 Super Cab 6.8 V10. Great condition inside and out. 68,000 miles. Began smelling fuel (gas) a few days after driving it 250 miles from purchase location. Traced leak down to the top of the gas tank. Staining was visible around the rear vent. Applied about 5 psi to the tank and sprayed soap around until I saw bubbles coming from a hairline crack at the rear vent connection. Its where the fitting for the hose comes out of the tank.

My first choice would be to hot weld the crack. I'm not very comfortable with the idea of a heat source near a gas tank. I'm not sure, but the heat from the plastic welder might be hot enough to ignite fumes? Second option is to try some industrial 2 part epoxy (PIG) and seal it with that. Is there pressure inside the tank, and if so how much? Can try this fix with epoxy or JB Weld?

Ford Super Duty (1999-2016) :: 2004 F250 - Fuel Pump Relay Location

I am trying to diagnose my fuel system, but I cant seem to find the fuel pump relay. My truck is an 2004 f250 crew cab work truck with 5.4L. it seems that the relay can be mounted anywhere from behind the radio or in the engine compartment as well as built in to the fuse box under the steering wheel.

Ford Super Duty (1999-2016) :: Fuel Leak Under Hood?

I noticed a raw fuel smell today while driving. I came right back home & found fuel spread all over the under carriage. I popped the hood & found the fuel bowl and surrounding area wet as well as fuel puddled up in the valley.

Before I tear into things I'd like to get input about common causes. I've read that the separator valve gets it's o-rings eaten up by modern fuel. Could this possibly be it? If so are there special kits that deal with the low sulfur & biodeisel?

Ford Super Duty (1999-2016) :: 2001 F250 V10 - Bad Oil Leak

I have been leaking oil on one of my work trucks. I do not know what the part is called or named. the leaks seems to be coming from above or behind a part that the driver side motor mount. As you can see in the image, the part has a sensor and a concave dip that runs along the middle of it. Well, I stuck my fingers behind that and it has a dip on the other side too which face up and that dip was puddled with oil. I need to know what that part is called or named or what is directly behind it that can be causing the leak. I hope its just a gasket and it is not cracked.

Part that is leaking behind. 2001 Ford F-250 Super Duty V10

Ford Super Duty (1999-2016) :: F250 - Head Gasket Leak?

I've been trying to figure out what is going on with my '99 F-250 V10, you can check out this thread for the back story

[URL]....

I did a compression check and the results seem inconclusive to me- see image.

Before I did the compression check I started to take the intake manifold off to change the gasket set and it's about 50% done. I'm at a crossroad now. Do you think I should finish switching out the intake gaskets or do you think it's more than likely a head gasket? I would hate to put it back together, it still smoke and have to take the intake and everything else back off to do the head gaskets.

Someone had mentioned a possible small crack in the cylinder wall that is closing up when the engine gets heat in it and obviously doing the intake and cylinder head gaskets would fix it if that's the problem.

Ford Super Duty (1999-2016) :: 2001 F250 Under Dash Leak

I'm from SC where we are currently getting our rainfall for the next 3 years, so it's an occasion to find leaks. My 2001 F250 has developed one right in the middle of the passenger side dash, I saw it running down a white vacuum tube and dripping off to the floor mat. Is there a place in the cowl that will hold water and leak?

Ford Super Duty (1999-2016) :: F250 - Leak In Front Axle Shaft

Check out the pics. 99 f250 4x4. I have a leak in my front axle shaft. It looks like it is coming out of the dust cap on the end of the front shaft. I am pretty sure it is differential fluid from the smell. Is there a seal before the dust cap? Is the shaft hollow with fluid in it? I thought it was just in the differential and if it leaks it is at the seals where the axle goes into the differential not at the otter end.

Ford Super Duty (1999-2016) :: 2008 F250 - Exhaust Manifold Leak

is there a set of headers for my 2008 f250 5.4 rwd that will install somewhat easily without me throwing tools across the garage? I see a lot more options for the older trucks. I have a pretty annoying exhaust manifold leak and I figure I might as well throw some headers on if im gonna be in there. I really want to go for sound rather than power. I think I saw a set by flowmaster that looked decent.

Ford Super Duty (1999-2016) :: 2000 F250 - Rear Hub Seal Leak?

I have a 2000 F250 4x4 7.3 - About a month ago I drove across town and then noticed a strong hot brake smell from the rear of the truck. When I drove home about 2 hours later it was gone and didn't return until today. Today I stopped at a light with my window down and got the same hot brake smell, looked in the mirror and saw smoke coming from my drive's side rear wheel.

I carefully drove home (the smoke was now gone, all i did was cycle the parking brake release a couple of times) and pulled the wheel off. Rotor was really hot but smooth and clean. Brake caliper and pads looked great (no sign of the pads glazing or dragging, dry as a bone). The inside of the rotor was wet with oil. The brake shoes and components were soaked with the same fluid/oil.

Does this sound like a typical hub seal issue? Excuse my ignorance since I haven't had the rear hubs apart before but does the gear oil in the rear diff go into the axle tubes? I know the front tubes are dry but I didn't know if the rears are different. The amount of fluid on the brakes seems to be more than the little bit that is inside the hub. I need to pick up the parts and rent/purchase a couple of tools to replace the seal so I want to be as sure as possible that I'm on the right track...

Ford Super Duty (1999-2016) :: 2006 F250 - Coolant Leak Only When Truck Is Cold

I have a 2006 Ford F-250 coolant leak only when the truck is cold. Ive noticed it in the morning when I leaving for work. It looked liked it was coming from the passenger side yesterday and today it's on the drivers side when I'm sure is because my driveway has a small tilt to it I've looked everywhere I could under the hood and don't see it leaking.

I don't have any temp problems or white smoke and my coolant level has changed that much and for a few days the drip stopped now it's back. I tried to search for the answer but can't find it. I'm just wanted to make sure it's not the head gasket but I'm sure I would have a sign it it was. I will include where I saw it dripping from. It's parked on flat ground here ... That's where I saw a drip coming from driver side ....

Ford Super Duty (1999-2016) :: F250 - Header Gasket Leak / Passenger Side Only

1999 f250 with some mild upgrades. Trucks got 189,000 miles. Stole it from an older guy for 4k. In fantastic shape. As the weather got colder I noticed an exhaust leak. Took it to a muffler shop only to find that it's got an aftermarket header on the passenger side only. Is that common to replace only one side?. the gasket has gone bad and needs replacement. I wanna replace both headers?

Ford Super Duty (1999-2016) :: F250 - Exhaust Manifold Leak On Passenger Side

Should I attempt to replace the passenger side manifold with what I can get from Napa. I would rather pay 100 bucks for everything and do it myself. But, Im concerned about replacing the studs. From what I have read the studs seam to be the problems for most leaks on these vehicles. I have torque equip. and other tools to do the job. Just want others opinions about this project. How hard really is it? 1999 5.4L F250 SDuty....

Ford Super Duty (1999-2016) :: F250 V10 - Leak From The High Pressure Hose On Gearbox?

My uncles 1999 v10 started to leak from the high-pressure hose on the gearbox. Replaced the hose which lasted for a short time but is now leaking at the same spot. The hose swivels, is this normal, seems like a dumb design for a pressure hose. Also is there a certain trick to doing this hose? He also insists on using PS fluid instead of the ATF it calls for. Could this cause a problem with the seal?

Edit: Also the truck has been lifted on 35s since 16k miles and its now roughly at 170k. He tows with it as it is his work truck. But the truck is well taken care of.

Ford Super Duty (1999-2016) :: 2002 F250 - Diesel Leak On The Back Of The Engine

I have a 2002 Ford F2 50 that has a diesel leak on the back of the engine. I've already replaced the drain valve that was leaking. Then I noticed that the front of the engine was dry now but the back of the engine still has some pooling With a very small drip off the back of the engine between the transmission housing and engine. Not as bad as it was of course But still a small drip. Where this may be coming from? And how to fix it?

Ford Super Duty (1999-2016) :: 2005 F250 Seemingly Not Getting Fuel

2005 F-250, Diesel, 105K miles, all stock, fuel and oil filters changed in May, about 4000 miles ago.

three times in the last 4 days the truck has seemingly run out of fuel. Got a full tank about a week ago, at the same place I always go, so I doubt it is bad fuel. It ran thru a 1/4 tank with no problems.

4 days ago, it wouldn't start. It just didn't seem like it was getting fuel. It sat for several hours and then ran fine for about 15 minutes and then slowly died out. It wouldn't restart. It sat for 8 hours, and then started again, ran for about 15 minutes and I cut it off.

The next day, it started fine, I drove it 3 miles, cut it off, and an hour later it started but ran for only 10 -15 seconds and it slowly died out just like I was running out of fuel.

I started it this morning and it fired up right away. I let it idle in the driveway for 30 minutes, and it ran fine. I cut it off, went to start it 30 seconds later and it won't fire again.

The backyard mechanic I use for simple stuff wants to replace fuel filters and see what happens. BTW - twice when it wouldn't start, he hooked up his computer and it had no error codes. You can hear the fuel pump running when you turn the key on and the mechanic said he could feel the pump working when he put his hand on it.

Should I let him do that or is there something else we should be looking at?

Ford Super Duty (1999-2016) :: F250 V10 - Fuel Gauge Not Working

1999 F250 V10 gas. I changed out the fuel pump, and now the gauge doesn't work. Checked all fuses - they're good. Is there any possibility that I could have accidentally pinned the float under the pickup sock, or got it hung somewhere? Is this a common occurrence? Don't really want to drop the tank again - but looks like I will have to in order to check/fix.....
