I was talking to someone at a swap meet (I can't remember who, but I think it might have been Kevin 'Tee Tee'). We were talking about Tokheim pumps that have a sheet metal cap on the globe hole, but still have a socket under it. He said that Tokheim sold some risers that had a male socket one one end, and a female socket on the other. These would screw into the factory socket below the level of the dome, and extend up about 6 inches so the bulb will be in the middle of the globe.
Does anyone know if there's a source for one of these, either new or used?
