    I am getting my fuel pump & pulley installed tomorrow! Will it be possible to disassemble the stock pump from the filter to see how bad it is in there?

    Stock pump will slide out from the filter which shrouds it. Then cut the filter open.

    Did anyone buy a new snapring for the fuel tank? Dealer is saying it should be replaced rather than reused..I told them if they can get it today to get a new one but if not reuse the old one. Anyone ever have any issues reusing it? I know I should make a new thread but I figured more people here have probably done the pump swap and will see it.

    Upgraded my pump three different times. Haven't used but the original ring and o-ring.

    Correct me if I'm wrong but the Walbro GSS342 is the unit that'll work in 2nd generation correct?

    Yes. It is not a direct drop in though. You will need about 6" of submersible fuel hose, and a stainless zip tie.

    If you want to additionally install the external fuel filter, look to the part numbers earlier in this thread.

    Cool, thanks. I have an Aeromotive 10 micron filter with a ball valve that'll go on as well. Not a big fan of hose clamps so AN stuff will be utilized.

    Does the fuel filter get clogged?

    What if you were to pull the screen off the OEM pump, and put an external filter on. Would there be any repercussion from have the pump unprotected?

    That is otherwise known as the "sock." Its only purpose is to protect the pump. Not the injectors. You still need to remove the OEM filter and replace it with an external one.

    ~100-103 LPH. The factory system uses 43.5 psi. *Note*(As referenced from Delphi's OEM replacement.)

    For N/A use .5 to .6 BSFC (Brake Specific Fuel Consumption).

    For F/I use .6 to .75 BSFC

    Optimal LPH = (Max HP x BSFC)/ 1.585

    This formula, will calculate the flow requirements for Engine HP.

    Pretty quickly you'll see that the OEM pump is out of its flow capacity, at 300 brake HP.
