I have a bad duck bills in my aft vacu pump . Where do I buy them from and how do I know what model vacu gnerator I have, I have a 1999 Searay 400 Da I dont know how to replace them either. Is there a step by step process on this site.

Thanks
Paul
 
Try to test the system first to ensure the duckbills are the issue. You may have a leak somewhere else which is what happened to me (leak at toilet seal).
 
I have two questions . First how come I cant open links like that is posted above about the duck bills. It gives me Error messgae stating I dont have access. How do I get access this stuff.

Next question is I replace the the duck bills and I still have a leak because the vaccuum pump runs once awhile . How do you find the leaks in the system??

Thanks

Paul
