What is this item?
I tried to get a picture of it, but its tucked back in an area that won't show up. I first thought it was my lift pump, but after looking at the service manual, I'm pretty sure my lift pump had been moved to the tank. There is nothing attached to the back of my fuel filter bowl, and there is written on the radiator support that the lift pump was replaced at 75,000 miles.
The item in question sits farther back and closer to the engine than the fuel filter bowl. Its kind of long and skinny(runs up and down), black in color, and has what looks like cooling fins, almost like heat sinks. Its on the drivers side of the engine, towards the back. It seems like I've read of some kind of heat exchanger for the transmission? Is that what this is?
