I know I could use a typical electric pump but I really don't want to add wires and brakcets to my AAR or even either of the RTs. I'm aware they are better pushers and your point about pressurizing the entire line is logical. My thought of the pump on the engine is more from an appearance stand point not to mention there isn't a heavy fuel pressure requirement but in some cases a volume concern with a pump but I would think most any quality electric pump would out perform a stockish mechanical pump.

The other issue I am fighting is why should I have to do anything they worked fine for years and I guess the answer there is the fuel is way worse than I thought and/or I am becoming more in tune to the issue since it is longer between driving each of them now. I'm in PA for a couple of weeks again but I will start experimenting with different fuels when I get home. The Coronet has good fuel in it now so it will be a good test sitting for 2 weeks.
