95 7.3 spraying fuel

[TexasAggie09]

I pulled into the HEB parking lot this afternoon and smelled a strong smell of diesel. I shut the truck off and got out and I'm POURING fuel from the bottom of my truck under the engine. The heads are wet as is the turbo and a lot of the engine compartmen. With the engine on, fuel is spraying up from underneath and to the left (pass. Side) of that plasic cover on top. At a quick glance it looks like it's coming from a line possibly. The engine runs fine and I limped home. Any ideas what this is? I'm afraid I'm going to lose all my fuel among other things.

check the fuel lines, fuel plugs, make sure the fuel filter cap is on tight, and fuel drain plug is closed.

I've been reading up on the fuel separator valve and how it can leak (due to the o-rings) but I'm still not convinced that that is what's leaking. I haven't had much time to mess with this this weekend but I did snap a few pictures and take a video of what's going on. Does anyone have any insight based on these pictures/video? Thanks!

HOLY CRAP!! i wouldnt run that truck. looks like one of those fuel plugs on the head came off

What exactly do those fuel plugs do? I'm totally new to diesel engines...would the best thing for me to do be to get all those harnesses out of the way and see what I can find?

Its either a fuel plug or one of the lines that go to the FPR ruptured!

If you were closer to the DFW area I would come fix it for you but your like 4-5 hours from me.

I appreciate the offer...even if we can't do that. Either of those things...fuel line to the FPR (what the heck is the FPR? fuel pressure regulator?) or the fuel plug...are those expensive/difficult to fix? I'm pretty mechanically inclined but my "garage" is an apartment parking lot and I'm a broke college kid. Should I just start unhooking the harnesses and whatnot on top and try to drill down to the leak?

FPR is Fuel Pressure Regulator.

Both should be reasonable to fix! Try to move wires around and pin point where its spraying from.

with out getting your hand chopped off from the fan and belt.


just dig around with it off and look for any thing that will show where a leak can come from.
