Well, I couldn't find it on Ebay, so I may be just whistling up my sleeve here, but if it is on a fire service truck, it could be a pump cooler, or a radiator cooler, or a pump primer.
Since it appears to be attached to the upper radiator hose, and therefore full of water, I doubt if it has anything to do with fuel delivery. But I have been wrong a couple of times.
Let me know where to see the whole truck, and I will offer a better opinion.
