ROFL
Racecar part...need a degassing bottle that will hang off the fender and cowl support, and the Econoline bottle fit the bill just perfectly, right down to the two outlets on the top for return from the motor. It's an LT1 in a full size (Think Impala SS) sedan.
Was trying to explain how it was mounted to a buddy, and since i very very seldom work on Econolines now, I couldn't get a picture.
