Flexfuel sensor
 

Looking for the part number for the flex fuel sensor .
My truck didn't come with flex fuel. It's a 2015 4 Silverado 5.3 with 373 gears . Looking for the sensor and where does it connect to .

Thanks in advance

not sure on number but its in the fuel tank. HTFU BTW, I was kicking it with your SCTC compa's at truck wars.

Flex fuel sensor connects up under the cab near one of the crossmembers. It's a dummy plug that most of the of trucks have dragging along up here when they are packed full of mud lol.... you always see it hanging underneath as not one here is ordered flexfuel as e85 doesn't exist here anyway. You have to cut the fuel line and or add the line from a flex fuel truck to add it.

I'm picking mine up when I go up there for vacation.

It is not in the tank either.... youll see the dummy plug on the drivers side of the truck... about a foot or two in front of the tank on the frame rail.
