(OP) Well, that is the first marina that I've run into that only had the high-speed nozzle. The good news is that I don't usually fill up there. Googling the topic it sounds like this is also an issue on diesel truck forums as well. I did a quick check on Defender and they do have a 2" as well as the 1-1/2" fills. Scandvik Diesel Deck Fill
. I have a lot of projects that would trump that ... but maybe down the road. Until then, I guess I know to use a jerry can at that marina.
