Yes, I have done this several times. The gas tach does NOT work
automatically with a diesel engine. You need a diesel tach and an
alternator with a "W" connector. If you want to use a gas tach you will
need a signal converter. These are commercially available. They still
connect to the "W" lead of the alternator but they convert the
electronic signal to one compatible with the gas tach.

Gas tachs connect to the ignition coil. Diesels do not have an ignition
coil.

If you want more info feel free to ask.
