1997 F250 7.3 powerstroke, diesel leak

I have a leak somewhere under the turbocharger. It appears to be coming from an area where two copper tubes are tied into a fuel pump? I'm not sure what is exactly leaking but could use others thoughts.

this is to john buccella, it sounds like your fuel pump is going out. I had the same problem with mine with the same symptoms. Its called the '' high lift pump'' at auto zone and runs around $100. its fairly easy to replace and i recommend that you replace the hoses going from the pump to the fuel filter canister as well.

I have a 95 powerstroke that is leaking fuel when running. It appears to be on the passenger side near or above the starter. I

Can't tell but i think it is dripping out of the the hole on the bottom of the engine block, this is where the water bleed off valves dumps through when i drain the the fuel filter bowl if there is water in my fuel. Can this be the actual valve or o-rings that seal the bleed off valve? I checked on the fopsode of the the intake manifold and did notice some liquid in the valley, i don't know if this is diesel or water in the valley from the rain dripping down onto the valley, but it only leaks when the engine is running. Am i correct in thinking there are seals for the bleed off valve that can go bad? Please email me at or feel free to call me at 425-343-8284. I have tighter every hose for fuel and none are even wet with fuel. Any ideas please get ahold of me. Thank you, Brett.

I have a 95 f250 powerstroke that is leaking fuel when it is running and it appears to be leaking onto the starter and also its coming out of the bottom of the flywheel cover. When I shut off the engine it drips like Up to 10 drips but when its running it will drip 1-5 Drips every 30 seconds or so. But of course when I went to the auto parts store and looked for the leak emahen it was running, it wouldn't leak. I believe the leak is coming out of the drain hole that is for the bleed off valve when there is water in the fuel filter bowl. Are there o- rings or seals that seal that bleed off valve? And are the seals easy to change? Has this happened to anyone, and am I driving a time bomb if this isn't fixed immediately?

Fuel leak on 02 7.3 Top of motor is dry, including the valley, the passengers side front of motor is soaked??? ( Thanks!!

My son has 1997 F350 7.3 turbo. He had fuel leaks in the valley. After finding the leak which was the orings in the high presure regulator. He went to Ford and they said low sulpher fuel destroyed the orings and they didn't make a repair kit but would sell him another high pressure regulator for $450.00. We carried the regulator to Cardinal Rubber and they had all the orings to fit the high pressure regulator and it was fixed for less than $ 5.00.

Reply to #33 Tom:

Try changing the fluid and filter in the transmission. Had a Ford mechanic tell me it was a torque converter issue, and changing the fluid a couple times will help it shift better. Truck still has the issue, but when I change the fluid and filter, it gets better. The more often you change it, the better it will get.

Hi all! I have a 97 F-250 7.3L Turbo. I have had it in the shop and had $3000.00 worth the work on it and that was mostly for a fuel leak. Well, the mechanics replaced the fuel filter and 2 hoses # LMKFL35 and LMKFL34. I don't know if these are fuel hoses. You will have to excuse me as I am just learning the diesel engine. I am use to working on the gas engine. Anyway, they found the valley of the engine full with fuel. They resealed the fuel system in the engine valley. They replaced the Fuel/Water Seperator Element. Well, now it is leaking fuel again. I was nearly out on my destination of a 1700 mile trip to see my sister who is has end stage cancer. I was leaving Salt Lake City and was heading for Wyoming. Luckily I caught this fuel leak before I got into Wyoming as there is nothing out there in Wyoming. It is just me (a female disabled women) and her dog traveling alone. Luckily, I have some expierience with automobiles. Anyway, I do not know what could be causing this to leak again after the mechanics said they had it licked. I can't travel from Salt Lake City to Houston, TX with my vehicle doing this. I love my F-250 and would never part with it. I bought it brand new and it is my baby. Can anyone out there give me some suggestions. It is leaking at the bottom of the engine near the oil pan as that is where it was leaking before. My mechanic told me if it were to leak again he would have to take out the turbo to maybe see what would be causing it. This would cost me a arm and a leg for this. I do not think it's near the turbo. I am getting the impression that I am being raked over the coals here. Any suggestions would greatly help. Please e-mail me as I would best see responses via e-mail. Thank you so much,

Sue and Samantha(puppy dog)

Thank author of this post/comment"Trans o.d. light flashing"

Please be advised, sometimes it is not the trans!

I spent over 4, 000 dollars to learn it was the instrument cluster!

My truck spent the better of 6 months in and out of the trans shop, they just kept throwing parts at it.

A trip to Ford proved out that all I needed was a junkyard cluster.

I had that problem with my 97 7.3 Turbo power stroke. Your Glow plug relay is bad. You can get this at almost any part store. I believe the last time i replaced mine it was under $30.00. It is located under the cover (on top of the motor that covers your fuel filter. It is a round cylinder with 4 studs coming out the top. Remember before you replace this to remove your battery cables first. This will help with the cold starts. It also helps to plug it in overnight, but this should fix your problem.
