Thank you Leon for producing another fine product.
In my experiments with alternative fuels, I have tried diaphragm pumps, trash pumps, and belt driven straight gear pumps. In choosing the right pump there are always compromises like weight, fuel source, volume and mobility. Yours is by far the best overall in these. It is very fast, easy to move and the electric motor is so much better than starting an engine in most places I collect oil. I am happy to share this review and recommend this pump to my friends. I wish I had had this pump from the beginning.
Best regards,
Nolan
