Don't want to put an electric pump on most of the cars for a number of reasons and no doubt I could prime them but I really don't know why I should have to. They all have aftermarket stock pumps and clear fuel filters. It's not a huge deal but mainly irritating cause I like my cars to work right. The one with the least trouble is my dually which is a GM with a Q-jet, it has the carb filter with the check valve and even after a month or so it fires after minimal spinning. I'm reasonably sure I'm not the only one with this issue and I'm thinking surely someone make an inline filter with a check valve.
