Justin,
That looks like an electric fuel pump that someone screwed to the right side inner fender.
I see it is not hooked up.
Makes one wonder why it,s there especially knowing the truck is only showing 38,609 miles.
By the way THAT is a REALLY SWEET TRUCK.
KEEP it that way and Honor Your Grand Dad.
regards
steve sr.
