Jeff, thanks for the explanation on the pump dates. My 68 has the pump in the bottom picture on it. Been running it for 10 years now. Hope it keeps pumping. I still have the exact same box like in the picture also. I hope the pump I have coming is suitable for my 66. We'll see, we'll see. The pump photo's are great, Thanks, Bill.
GD64, thanks for the link, I have added it to my list to check out if what I have coming doesn't work out. Bill.
