I've been looking at Gilbarco 1004 and 1006 pump pictures here on the site as well as reading some posts. Very Interesting.
What is the difference between the 1004 and 1006 models. I think on the 1002 vs.1004, the 1004 has the retracter cable for the hose, not sure about the 1006.
Also, do they all have a sight glass?
Any other differences anyone can identify would be appreciated.
