Good analysis. There are a couple of easy tests for the accumulator - Clamp off (vice grips) the one hose that comes off the end of the accumulator by itself. This is the low side relief. If it is leaking badly internally, this will fix the pressure problem. You will still have a hot start issue, but the fuel pump pressure will not be able to bleed off back to the tank and should build up quicker. An alternative or second test to this is to disconnect this same hose from the accumulator, and then clamp it off. Put a short extension hose on the accumulator and direct it into a jar. Jump the RPM relay to activate the fuel pump. If you get more than a 1/4 cup or so of fuel out of the accumulator (you should expect some as it compresses), it's leaking internally.
