Re: [DML] Accumalator

Nick, The accumulator doesn't have anything to do the with the bucking, it 
just holds pressure on the system after the car is turned off. 
#1. My first question is: How old is the fuel pump
#2. How much gas was in the tank
#3. Does the bucking start when the voltage goes down to 8 volts.
Answers to the question: 
#1. If the pump is old and as the level of gas goes down the pump will not 
self prime it's self. The roller bearings that actually do the pumping will 
wear and the space in the pump will widen and this could be one problem. Some 
cars have a primer pump totally immersed in the tank. They must have had some 
forsite into this problem.
#2. The level of gas coupled with the old pump will have a harder time in 
keeping gas to flow. Thus a bucking if it misses a beat.
#3. If the voltage drops that low, then the relay in the RPM relay will open 
and shut off the pump for an instant. Thus the bucking.
#4. Check the connections to the Inertia switch. If they are not tight, they 
will heat up and seperate for an instant and you will have the bucking.
