The smaller accumulator is a crossover from the 911. My guess is the larger accumulator was put in place in '78 due to the greater output of the intercooled Euro engine. For racing purpose (homologation) the fuel system was overbuilt on these cars. The system pressure for 930 CIS is also much higher than that of the 911. It would be interesting to see if, or at what point, the small accumulator would restrict power on a modified engine.
