slanty 8 Posted April 1, 2018 Share Posted April 1, 2018 Recently the boat has become quite smelly after a period of motoring. I think I've narrowed it down to a leak on the high pressure side at the injector - see photo. Just wondering if its a good idea to snug it up or do i need a pro? If tightening it up is the the upper or lower nuts? All thoughts appreciated. .. Quote Link to post Share on other sites
wheels 543 Posted April 1, 2018 Share Posted April 1, 2018 The upper nut. The one with the line going directly into it. Give it a nip up. The lower one is the return line and has no pressure.Then give the nuts a wire brush and spray a little protective paint around them to stop rust destroying the threads. 2 Quote Link to post Share on other sites
