[DML] Re: Fuel pressure/accumulator question



A bad accumulator cannot be definatively tested in this way. I had a
car with the classic hot start symptoms. I removed the return hose,
did not see ANY fuel come out and assumed the accumulator was OK.
After chasing the problem around I replaced the accumulator and
corrected the problem. I cut the old one open to make a definative
analysis and discovered the return port to be completly blocked by
bits of the diaphram. I guess you could poke something into the port
to make sure it is clear before testing in this manner, it may make a
difference. The port has a small orifice inside to limit the return
flow so the pump can get up enough pressure to get the motor to run.
