AAH - interesting speculation about the accumulator. Typically this tends to be discussed over hot start problems? But one of its roles supposedly is to smooth out variations in pressure from the pump. I can't offhand visualize how those would happen - it is a roller or vane pump, which sounds like its output pressure should be pretty steady. But typically what we know is system pressure, which is past the accumulator and the FD pressure regulator - and I've not seen that fluctuate.
