I installed a so-called "leakless" Model B-style pump on my 1929 Model A (which has a 1932 "C"-head on it), and it leaked from the packing nut, the rear greasing port, and even from the top mounting bolt! I then pumped some grease into it, and then added a tiny O-ring to the brass cover over the greasing port, and the leaks finally stopped. (The leak from the top mounting bolt decided to behave shortly after that, for some reason).

It worked fine until recently, when it blew-out big-time! It had only had about 700 miles on it when it failed on me recently, and regreasing the rear port did nothing to stop it.

I will never buy one of these again; instead, I sent it to James Rupert for his expertise in rebuilding it. Once I get it back, I'm hoping I'll have better luck with his rebuild work than I did when it first came to me new (and "leakless").
