Here's one to consider: For the momentary prime switch,
use a double pole, double throw switch. Wire one side as NO to activate
the high boost for prime, and wire the other side as NC in series with your low
boost switch. This prevents both high and low boost being activated
simultaneously -- which could happen if you accidentally bump the prime button
while the low boost is on. Dunno what would happen if both high and low
are turned on at the same time, but I've posed the question in the past and
nobody seemed to know. Given the price of the pump, why not spend an extra
buck on the switch and be safe?

[And no, other than priming, I've never used the boost pump on
2 ES's and 1 Legacy! Took my last Legacy to dens. alt. of 19K once and all
the boost pump did was make it run rougher. Problem up there is not enough
air, so more fuel pressure doesn't do much.]
