Questionable Leak

[Wardster]

'03 Duramax/Allison with 104K miles.

 

Within the past week I noticed a couple of different drips on the floor beneath the truck. The first appears to be coming from a gasket on the transfer case, so I was wondering if any others have had the same problem and what costs are involved in replacing it.

 

The second leak looks like it may be coming from some type of cooler located in the front of the fuel tank. The lines look like they run from the tank itself, but I have no idea what it is for. As I indicated in an earlier post, I made the switch to B20 (biodiesel) about 175 gallons ago and I am not sure if that has anything to do with it. Thanks in advance for any comments.

The cooler on the front of your fuel tank is your fuel cooler. Any liquid leaking from there is fuel.

I had one of our mechanics take a look at the truck and he said the only leak he could find was the one at the transfer case. It had already coated everything else behind it, including the fuel cooler. I need to pick up some of the Auto-Trak II fluid as indicated in the owners manual and get the levels back up, then make an appointment to have the gasket replaced.
