Roy and Bill,
I rarely get stuck with the big nozzle pumps but both of these approaches are good ideas. I have a wood shop so it would be easy to make something that would work. Roy, if you get a chance, post a photo of your device, seems this is over due for me given that Flying Js, which I have used a lot due to the RV lanes, are now pushing B15 to B20 in many locations. I do not like that level of biodiesel sitting in my tank in the off season so I avoid them now.
Roy, is 1/4 inch fine enough or if you could build it over, in some of the most useful step area would you use a couple of 1/8th inch steps to enable higher flow or is this fine at 1/4 inch?
