At first I thought this was a low profile aviation pump.( Low for wing clearance) But has a globe mount, and I don't think any aviation pump would have a globe on top, and then how would they measure the fuel. All the short aviation pumps Iv seen had a computer on them.
You are probably not far off a gentleman came over and looked at it today and said they had one just like it at a airfield here locally and it was serviced by Texaco. He said there was no need for the computer because the hose had a counter on it that measured how much fuel went into the plane.
