hey guy here is my problem I have a 1996 mack / BPL 1200 HDR KVM 32XL Im not familiar with the accumulator system on these truck and how they operate. Can someone shed some light on this subject. The only thing I can get from other pump co is not much help. OK here is what its doing when we got the pump I thought it was broke I heard this noise which I thought it was gears grinding but it was the accumulators cycling, well thats ok but then one day it quit cycling. its working now but that worried me things don't fixed itself so if someone has more skills or knowledge hit me up at motorob0405@aol.com or 4042275847 send a PDF,Video ,break down anything I need to know more.

thanks Robert
