Hey guys my fuel pump went out and its been about a little over three weeks since I drove my truck. I was suppose to fix it by the Chevy show but didn't get a chance to because of money and also because i left out of town. Am back now but my question is does anybody know the part number for a fuel pump. I have a 99 s10 blazer 4.3 automatic 4 doors. I want the ac Delco fuel pump because it is oem. There is two types that I found one is part number MU85 and the other is MU1063. They sound the same MU85 comes with sealer the other one doesn't and the rest sounds the same. What is the difference and how would I know which one to order. (Do I have to wait till I take out my tank to see which one I have?) Let me know what I can do guys. Thanks a lot
