    Ok, with the exeption of you radix guys. I need to know who has installed a walbro pump in a 04 or 05 with a returnless fuel system. ( In tank Pump) I have a walbro gss342 pump for my denali, the walbro pump is about 1/2 inch in diameter smaller then the stock pump, I am trying to figure out what I can do to make it fit snug. I dont really want it free floating in there. Granted the fuel pump sock will help support it some at the bottom. Need some help here please..

    The same thing happened to me, I was sent the wrong pump for an '05 silvy I installed a Radix on, the '05 had a larger diameter pump than the one i received. I bought another one that fit.
    I can't think of anyway to secure it, you might want to buy the right one, I know it's a pita though.

    good luck,
