Great news, I get to order another VP44. After thirteen months my rebuilt ip died. Yes I was on 5x5, the fuel tank was low so I probly sucked some air and blamo another dead VP. I guess what I would like to know is what rebuilder seems to have better luck then others. Is the $1600.00 dollar pump better then the $949.99 dollar pump. Any help in this confusion would be appreciated. Thank you................. Ran..... Yea I know- P pump it!
