Just looking for help identifying a the hoses in the picture below. I've looked at the coolant system diagrams (specifically the one here: viewtopic.php?t=54222#p541602 ) but can't really work out where that blue-tee piece is. Obviously added by a previous owner but I don't know where in the system it is or even if it looks alright.
I took this picture under the driver's side of the Bongo I've been looking at buying. You can see the fuel filter and air filter housing above it. Apologies that the pic isn't the best quality.

Here's another pic of the underside (looking toward the front). I've circled the coolant drain nipple on one of the pipes there. You can see that the underside, in general, isn't too bad.
