    Default Fuel pump on the 8100 vortec again...

    So I have heard that the 8100 vortec had some fuel pump issues and my truck's problems point to needing a new fuel pump. So I will be needing a new fuel pump. My question is should I order another on from GM or is there a better aftermarket company I should go with?

    I would go with any trusted aftermarket pump over a stock one from gm. It'll save you a ton of money and like you said they had problems with these stock pumps. I just replaced mine this winter. Just one tip I learned is when you get a new pump make sure it comes with a new wiring harness/connector because the stock ones have been known to have caused problems as well!

    ^^THAT! I went with 2 GM ones when mine went out and wound up having the 2 GM ones go out 2 weeks apart from each other. My brother ordered an aftermarket pump (can't remember the name) and as well as a connector. Has been fine ever since.

    I went with a napa fuel pump. I have never had a problem with napa brand products.
