[DML] Re: Purpose of Fuel Accumulator



You are right, the accumulator has 2 functions. One is to maintain
"Rest Pressure" so the motor will start when warm-hot without the cold
start system. The other function is to reduce the pulsations from the
fuel pump. It does affect idle quality when the accumulator is bad and
is noticeable. 
 Wear eye protection and gloves and keep your mouth closed (Ha Ha).
Use proper fitting wrenches, hold back and DO NOT allow the metal
pipes to twist. You may have to replace the short rubber line if it is
in bad condition. If your accumulator is throwing chunks of diaphram
(little black pieces of rubber), you will see them if after removing
it and you shake it they will come out, then drive the car for a while
and replace the fuel filter. The filter will fill with those chunks so
it should be replaced too, just not at the same time to give all the
chunks time to get in there.
