I say newish cause I jumped the fence from the 48-56 section. Just got a '96 cclb 4x4. It was a construction company work truck, so it's had a tough life. It's had some money spent on it, and it runs good, but it is puking fuel at a pretty steady rate. It looks like it's filling up the valley and running down the back of the block. I felt around and didn't see an obvious culprit. It also seemed to a lot worse after sitting in a warm shop vs. 30° outside temps. Any weak links or trouble spots to check first? Here's a pic of the junkyard refugee, after I ditched the utility box, and dropped on a donor box.
thanks
Nice find man!! The best thing to do is start it, let idle, and climb up there start looking around. It's really not that horrendous. It's either a fuel line going to the heads, the pump, or the bowl itself, but you should be able to spot it pretty quick if it is leaking that bad. If you can afford E-Fuel, or piece together kit yourself, it's the best and first upgrade I would do to an OBS other than the downpipe and Air intake.
I agree with Byron and Tom. Most of us have been down that road one time or another. My suggestion is to take some paper towels and with a long screwdriver, push / pull and mop up as much liquid as possible. Once the valley is somewhat clean it's a lot easier to find leaks. The actual fuel bowl itself has been known to crack at the bottom contributing to leaks. The fuel pump does have a weep hole at the bottom towards the passenger side, hard to see but fingers can find it if everything is clean. Just be careful as climbing up on the engine with it running is somewhat dangerous, just be alert please.
Thanks for the tips guys. I've never messed with a diesel powered vehicle, so it's been a little intimadating diving into this. Guess I'll roll up my sleeves, and see what's going on.

Don't even sweat it. You can't really mess up anything as far as digging into the fuel system....and we are here to help. Keep us posted.
To add to Jims advise,also be aware of the hose running from the radiator to the degas bottle.If your like most guys,you lay on the engine
compartment on your left side.There is a small plastic nipple on the radiator that this hose connects to.Its easy to snap it off with your weight.
You might want to remove the hose,just two small hose clamps and the hose pulls free from the degas bottle and radiator.
This from my experience,there are any number of plastic/electrical connection on these trucks that can break if you get to
carless.
A topside creeper makes working in the engine bay far more civilized. Definitely worth the investment, in my opinion. I did not go the e-fuel route, but did replace pump and all the associated soft hoses when mine started leaking.
So I think I have it fixed. Replaced fuel pump and lines. It was spurting out the weep hole on the underside of the pump. It appeared to be a fairly recent replacement. When I took it out, the push rod just fell out and was loose in the pump. With the new pump, lines and clamps it seems to be high and dry. Just wondering if it's just a failure of a cheap pump? Or is there a larger issue that would cause premature failure?

I doubt it. All new pumps are made by Carter and all are the same, if new. Probably the other owner pulled one from a junk yard and installed it.
