Tube diameter...LAPump
When I ordered my pump from LA, it said to not cheat on diameter. I measured just behind the head and at the base and the chart said to get the 1.75. When I got the pump, man, I had to really lube my head, to even stuff my unit in half-erect. After I finally got started it was OK but should I have gotten a larger cylinder? The head is a tight squeeze but the shaft still has room. Is this abnormal or something?
