2000 F350 7.3L

It looks like I have the fuel leak coming from somewhere within the valley. From what I read and watched, its likely either the filter housing or the fuel line. So, I am gonna rebuild the filter housing and then also replace the fuel lines while I have it out (cuz why not).

With that being said, while I have everything out, is there anything else you recommend I replace?

The engine also appears to be leaking oil, but from what I have seen in some videos, there is a chance that its just black fuel that picked up some coloring from residual oil laying around the engine. However, I will have it open on the top, so I am looking for any line or fitting replacements that are recommended. As I get everything out, Ill clean it up, but I'm not sure without starting the engine back up, if I'll be able to see where exactly the oil could be coming from. Hopefully the oil I see dripping off the back underside is either part of the fuel, or at least coming from the top. I really am hoping no leaks are coming from anywhere else...


While I'm at it, I also noticed that the green vacuum line that connects from the air intake is severed, so I'd like to replace that while I'm in there. Does anyone know a part number for that? And, also, need a master cylinder cap. Not sure where the last guy left it, but if anyone knows the specific part number for that, I would appreciate it.

Thanks.

 

One reason "why not" rebuild the housing and replace the lines is the loss of opportunity to learn, know, and recognize what actually caused the current leak.

You can remove and reseal the fuel bowl, remove and reseal the fuel drain valve, and, remove and replace the hard fuel lines in the valley... and still have a fuel leak, due to a distortion of the fuel filter gasket in the fuel filter cap.

Imagine the frustration of putting in all that work, only to still end up with a dirty valley again, drenched in fuel.

The instructive value of locating the source of your current leak is not to be discounted.

 

Wastegate Lines

Fancy pants billet brake reservoir cover

Fancy pants Braided fuel lines

Fancy pants HPOP lines

If your HPOP lines are OEM they should be replaced, they age and can pop. OEM will be bare stainless braided, revised has covering.

 

You get a "like" just for the oh-so-appropriate thread title.

Along with what others have mentioned, take a peek up under the pedestal for the turbo to see if that is where your oil is leaking from. If so, you may want to consider these:

Awesome Guys, thanks for the responses and links!

I'll let ya know how it all goes!

 

Fuel lines replaced. HPOP line replaced, with new seals on the one I didn't replace and the plug. Rebuilt the fuel filter housing.

No leaks so far. Seems it may have been a success.

Now onto the brakes. Its losing fluid, I think from the front right, hopefully the storm passes tomorrow and I can get in and look at it. Any common problems with the brakes I should look for while I'm messing with it all?

Thanks again for all the help.

 

Most common problem with brakes are the slide pins siezing up.

 

If the rubber hoses are OEM I'd suggest new ones.

 

for sure if I was going to "dive in the valley" I would do the new turbo 360 bearings and new o rings on pedestal and check EBPV seal and replace.. I love my EBPV for use as exhaust brake..
