HMMM, That might just be normal... I don't know. The used accumulator you bought might be bad, that or the pump is just getting tired.

 

Well it's been over 2 years since I created this post and someone recently PM'ed me and asked if I ever figured this out. I guess I should update the group and tell everyone that I simply gave up on it and let it be. While I don't use the Rover all that often, it's still running and I haven't had any issues with the pump running more frequently than what may seem......normal?

Now if someone can explain normal operation on the EAS, that would be great. I've replaced/rebuilt all EAS components except for the height sensors. It seems to readjust often which causes the air pump to run somewhat frequently. Is this normal???
