Hi Redrotors,
you're correct, the part # starts with 460, and thanks for the information, I'll try and get a pump gear from a winnebago dealer
here are some other pump #'s you may find interesting, I have these two other pumps my friend just sent me
0 460 494 237
this is my mechanical tdi pump 0 460 424 222 , my 12mm pump, vw gas engine killer, I'll show them the engine first then my tailpipe later
any help or break done on the part #'s greatly appreciated. I'm going to send pics to Spike_tdi hopefully he'll post all of them. I have 2 winnebago pumps so one is for sale, I had to buy both.
