Thanks again for the input, I didn't get a chance to get into it with the 300D today as I was off helping put up a shed to house the budding PORTLAND BIODIESEL COOP's new processor. (gobiodiesel.com) but I will be back at it soon. While I like the IDEA of shop vac priming, I'm not sure I'd like to try it just yet. Love that '59 though. So, ideally I'd like to replace the hand primer,but the one listed in the Fastlane looks nothing like mine. Mine screws down tight and has a grey plastic handle which fits inside rather than over the pump body. I dont have a manual yet, so I cant really see how it would fit. Any idea? -Keith
