Lauren Report post Posted October 7, 2015 I need to replace the heater hose on my 2002 Holiday Rambler Endeavor 330 ISC Cummins. Any suggestions? Where can I get the part and how difficult would it be? I live in the San Diego area. Share this post Link to post Share on other sites
wolfe10 Report post Posted October 8, 2015 Lauren, Welcome to the FMCA Forum. Tell us what is wrong with your heater hose. It is common for the engine-room section to fail LONG before the rest of the hose which is protected in the basement. If that is what is wrong, you really don't need to replace the whole hose. Let us know and perhaps we can offer reasonable advice. Share this post Link to post Share on other sites
