    Ok, So I scored a government surplus 6.2 still in the metal shipping container. I intend on putting this in my dually tow rig. My questions are:

    1. Does the injection pump require 24 volts for the fuel cut off?

    2. Are the glow plugs 24 volt?

    3. Will I be able to use the water pump that is on it, or are they different?


    I think that is all for now, unless y'all can think of something I am missing. Thanks in advance!

    Mike

    As I understand it...whole truck is 12 volts..except for starter. Glow plugs are 12 volts units with a big resister in series to drop voltage from twenty four. Everything else, lights, fans, guages, etc is 12 already..including the fuel cuot off solenoid in the injector pump.

    However... I learned all this infor from this forum...I would confirm it with somebody who has done it.

    Re water pump. I haven't heard of any think. What kind of engine was in your tow ring..454 big block or diesel?

    Thanks for the input. I just recently bought an '84 dually that was originally a 6.2 but the PO had swaped it out for a 350 when the 6.2 died. I'm going to put it back to diesel.
