    Are these engines interchangeable? If my truck has a dt466 in it, can it be replaced with a dt466E?

    Anything is possible, just depends on how deep your pockets are.

    I'm not positive but I'm reasonably certain the 466 is a mechanical fuel pump and the 466e is electronic. Meaning you'd need an ecm and appropriate wiring harnesses. Won't be too easy or cheap

    I know a 466B will bolt in where a 466A was, but that was 20+ years ago.

    DT 466 A & B were fully mechanical, while the E series is full electronic, including most dash gauges.

    It may can be done, but I wouldn't try it, even with a donor truck, because the wiring nightmare.

    Anyway, a 466 B is a much better engine that is easily turned up, and will give less problems and last longer than early E series engines.

    Probably easier to make the electronic engine mechanical.

    How can you tell if you have a dt466 or a dt466E?

    Most likely by looking at the fuel pump.

    We had several single axle dump trucks with dt466 mechanicals in, and 1 with a dt 466E. Stick with the mechanical, if it’s blown, they are cheap to overhaul. And they are peppier than an E.
