    1/2" line, single Bosch motorsport pump.
    Previous owner stated that with this setup he never had any surge and that it worked great, never had a problem.

    Now, my issue...I believe he means it to be a Bosch 044 pump yeah...
    I have contacted many suppliers, and I received the same response, that an 044 requires a primary pump to feed it, usually a intank lift pump, and not to be used as a standalone pump. There is no intank pump in my setup, as in, there is no option for intank.

    In my research I have read many forum posts about Bosch 044 pumps.
    Most stuff i read said that these are pusher pumps, run inline after a primary intake pump, and that you shouldn't run a filter before them, as that can cause issue with the feed.

    I'm guessing that he got away with it as gravity feed was enough to feed that 044.
    Do you think I will get away with the same kind of set up that was run originally? (Just not with 1/2" fuel line of course)

    Or, is there a bosch "motorsport" pump, I can purchase that is a "puller" type pump. (coz if there is, I'm having difficulties finding it). Really, doesn't have to be Bosch, just a decent brand, but needs to be screw in type fittings style.

    Any help here would be much appreciated.
