    I looked at a couple places up here in Canada and they were unavailable but there appears to be one at PartsAvatar available.

    I ended up making a pump out of a Carter M4891 Hi flow SBC pump. It is rated at 12o GPH free flow. I basically just removed the Chevy arm and refit with a Buick arm.

    It was reasonably easy to do. It would have been super easy if the arm would have slipped inside. It is just a hair wider than the chevy arm so I ended up opening the channel up inside about 1/16" with a die grinder and carbide bur then a cartridge sanding roll. After that the arm slipped in ok. I was going to do a forum post with some more info.

    So any SBC fuel pump will work with swapping the arm?

    If so, what fuel line do you use if using a a Quadrajet and sbc fuel pump?

    Yes, the SBC CV mechanical pump I use, I got from Jim Weise when he built my current engine. Jim just swapped it to a Buick arm.

    As far as fuel line is concerned, the SBC pumps use the same 3/8 metal line with 5/8-18 fittings. The bends for the fuel pump outlet connection would be different, but that is about it. Or, you could simply use a conversion fitting from 5/8-18 to -6AN and use braided or push lok fuel line. All you would need is two of these, one at the fuel pump outlet, one at the Quadrajet fuel filter fitting,

    Or, you can use one of these in the later Quadrajets with 1" (1972 and up) inlets,

    And use an inline fuel filter in your braided line.

    There are Chevy fuel pumps (small and big block) that have that same deep bowl as the Stage1 pump. Just the pump arm, and make a line, and you can use them. Have a look on Rockauto. They have plenty of pictures so you can see what you'll need to do. Here is an example,
