Thanks for contacting GMG! We learn a lot from our customers and attempt to get back to everyone; but, it’s not always possible:(

If you have a non-sales/product question and are looking for advice, you must REGISTER and post your question in the FORUMS area.  This is to ensure that the Q&A will become public so that others can benefit from the exchange between GMG and you (so assume your Q&A will be public!).

If you have a direct sales/product question, please use the form below to send us a part request or to learn more about our military diesel generators. For all military generator parts or generator inquiries, please include the model #, part # (or NSN #) and part name as found in the military generator parts manuals. Please provide detail so we can ensure we understand your need. Contacting us via email is preferred as we receive many inquiries. Please remember that all general questions regarding advice, must be made through our FORUMS area and you must REGISTER to participate in the forum.

Fill out my online form.


Telephone: 802-659-4455

Our HQ Location: Please note that we do not have a retail location.  All sales are by appointment only.
