Hey, I had a pump blow up last year and I was able to repair it. BUT I just bought a spare one today for the low cost of 150.00us. I should have it on wednesday. Oh yea I installed the upgraded window reg. in my 5k with little difficulty. It seems to work O.K.? Not as nice as the cable version IMO. The cost was not to bad though it was 125.00us Marty S.
