    Where can I buy a larger fuel pump for my '04. I think the stock pump is not keeping up
    with 6-7 psi of boost and 44lb injectors. I did a search, but didn't find a source to call.

    Walbro makes the larger volume pumps. You may have to email or call them for your application.

    Just got mine this week too. Call Magnuson customer service & tell them you bought a used Radix off Ebay or something. They included installation instructions when I asked.
    Gone, but not forgotten!
