    Default Mechanical Fuel Pump Question

    I am gathering parts to switch from blown carburated to blown injected on e85 on my 540 bbc and was wondering what size cam driven fuel pump I need to run. Any help would be greatly appreciated!! Thanks

    I've had years of good service out of an Aeromotive cam drive pump.
    It draws fuel up out of the tanks good.

    Yea that sound's right. I would make sure at the least have it flowed so you know where your starting at. It's safer that way.60 ish bucks well spent

    Like PITW said, that pump will be fine, and you HAVE to get any unknown pump flowed, or you are just throwing darts at the board in the dark, NOBODY can give you a base tune without knowing the volume/pressure/rpm of the pump. Its why you CANNOT use a Aeroomotive pump. Nobody is going to flow it for you, and there is no indication its even sized correctly for your application. There is a reason there is dozen MFI pump sizes. One size does not fit all. Each pump is application specific.

    I didnt gather that this was for a mechanical injection setup.
    For that Bob's right you would need an Enderle pump with a specific flow rate for the application.

    The Aeromotive pump I use is for a regulated system like EFI that I run.

    If you are running a mild ski boat and towing people on tubes, then the 80-A1 might be enough pump. But it is not near enough for a high powered, blown injected alcohol 540 racing engine.

    The Enderle 80-A is around a 4.5 gallon pump and the 80-A1 is around a 7 gallon pump. You might be able to get away with the 80-A1, but the Enderle 110 is the way to go in the high performance blown injected alcohol 540 racing engine.

    Also, Enderle just came out with a pump that is in between the 80-A1 and the 110, called a 660 or something like that.

    Lastly, these pump rates are not absolute--the pump must have a flow tag and if not then it must be flowed prior to its use.
