What is this device??????

Hi Peter, it looks like a heat exchange unit, are the hoses connected to two separate chambers?

Inside there is a large coil of I/2" pipe. On one end there are
two small openings, so that makes 4 large...two small.
The other question is what vehicle was it used on?

....to engine oil coolers for mid 50s fire trucks powered by a 248/270 GMC engine...

Heat exchanger for hot water on a CMP ambulance?

Peter,

Have a look at the attached images. I am fairly sure that it is an "evaporator" which is part of the kit for the WASP flame thrower as installed in a Universal Carrier. I do not have access to a parts list to verify the part numbers but from the research that I have completed FUL appears to be associated with Flame Thrower parts.

I would say Colin has it.

I was darned if I could think of a reason that you would want to heat up gasoline to the point of evaporation. But a flamethrower would be a good reason.
