fuel leak
next to my exhaust back pressure tube there is another metal tube that has nothing attached to it. (lower section) my truck is leaking in that area. can fuel come out of this tube? i cant find a pic anywhere of it on the web. thanks

Sounds like you are talking about the fuel bowl drain tube. If you open the yellow-handled valve on the rear of the bowl more fuel should come out the tube if that's it. You can rebuild just the drain or the entire fuel bowl for not much $$. Look for kits at riffraff or dieselorings.

That is the tube for the fuel bowl drain , Sounds like your drain valve is leaking.. it's not uncommon.
it is easy to replace the o-rings.
Here is a link. you can also find instructions on how to do it here.

If it smells like diesel fuel then it is for sure the fuel bowl drain valve. If it does not smell like diesel then it could be your water pump leaking and the belt slinging water over there but you would have engine cooling issues and the level in your degas bottle under the hood would be dropping.
I think it is your fuel bowl drain from the info you gave us but wanted you to know that there is another explanation for wet battery cables.

when its leaks, does it make it to the ground? if so where on the ground does it drop out at?
I only ask cause I have a intermitent leak and it is fuel. drops from the back from the motor and tranny area.
I have looked in from the back (I have a van) and can see the valley and it is moist, but nothing flowing that would match my drop. when it decides to leave its mark its about the size if a big grape fruit.
and doesn't always leave its mark. frustrating for sure.
bad thing is its hard to get the back of the fuel bowl cuase of the van part

MtDewX, There are two places your fuel could be coming from. The line that runs from the bowl to the back of the passenger side head suffers vibration damage at the clamp under the spider after a lot of miles. The other possibility is you have an o-ring that has given up on the fuel bowl or fuel line up in the front of the engine. Either way, they are pretty easy fixes. Just takes time to take everything apart to get to the suspect and then re-assemble stuff. Dry the engine valley really good with rags (stuff a bunch of them down there, let them sit for a bit, and then pull them all out). Then run the engine for a while and check the valley again. If it is wet towards the front, the fuel bowl seals are suspect. If it is only wet in the back, it is the line for the passenger side head that is suspect.

already replaced the passenger side fuel line. at first I thought it was oil, but it smells like fuel. and I thought the valley would have had more smell and more wet if that makes sense. anyway already looking into the fuel bowl. some seals have already been replaced, I just have to figure out which ones cause I didn't do the work. but if i dig in and find it was them. then I will not be very happy. no garage and winter is coming sucks on timing. lol
thanks

Fuel bowl rebuild/re-o-ring is not bad at all. Print Guzzle's instructions, pull it off, find a comfortable chair and go to town. Then toss it back in and you are golden. 2-3 hours tops, and you will have piece of mind for the next 20 years with those Viton o-rings in there.
