It is still a 12mm I had it at AFI in modesto and the owner mike went through it and said it was in great shape It just wasn't what I was needing for my truck I am just wanting a good stock dd. He was gonna do some work to it to make it work for me but decided to go with a stock pump from the wrecking yard. He told me it was pushing out 600cc's of fuel no problem.
