Just picked up a G&B model 80-18. My question is, what does the -18 designate? The pump has Mobil colors/signage. Everyone have a nice weekend. Thanks in advance for your help. RON - CONGRATS!!!

NO IDEA??

I went through all my G&B 80 literature and cannot find an answer for your question. In the parts/repair manual they mention that when asking about parts to be sure to include the complete model number, such as "Model 80-18," but they don't say what the 18 is for. Incidentally they also mention that there are the 80-1, 80-50 but they don't mention what these are either.
If you are interested I have sales literature and parts/repair manuals available for this pump, just email me if interested. jhsim@swbell.net.
