Weird part
I have an 03 Z71 Tahoe and I found this electrical device next to the fuel filter. The fuel line from the filter goes directly to this device and then a second line comes out of this device and goes to the fuel rail. Does anyone have any idea what this device is or does?

Re: Weird part
Looks like a fuel composition sensor, it tells PCM the ethanol content of fuel. Your truck is e85 compatible.

I know its E85 compatiable and tried that crap for two tanks back in 2007 and will never do it again. At that time the E85 was $1.99/gal and unleaded was $3.09/gal and while the engine ran smoother and seemed to have a bit more power below 3000rpm the trade off in mpg was not worth the price savings at all. I went from 17-18mpg down to 8-9mpg and used two tanks in one week effectively negating any cost savings.
