Very interesting for a couple reasons...........I was able to call Greg about 3 weeks ago. He has been busy on helicopters. I have sent fuel pumps and wobble pumps to Tom Haniford for years. He knew these were for aircraft and didn't mind. He said he did lots of wobble pumps and I've yet to see one in an automobile. He has done them for both the Franklin and Ken Royce. I wouldn't rub "aircraft" in his face, however. As far as I'm concerned, Grant's link is good. Dan
