wolfe10 Report post Posted February 26, 2012 Most just replace the pump complete-- a well known problem. But, you could check with Cummins to see if a seal kit (O rings) is available. Share this post Link to post Share on other sites
jc21014 Report post Posted February 27, 2012 We are going to be looking at a 2001 HR with the Cummins ISL 370. Is this problem only on the 330 or other models also? Share this post Link to post Share on other sites
