Tanner Posted January 31, 2016 Share Posted January 31, 2016 Hey guys, so tonight I went to start the mj and fuel starts pouring out between the rail and the regulator, my question is are there just seals inside the end of the rail that can be replaced or is that more likely a problem with the regulator itself?

schardein Posted January 31, 2016 Share Posted January 31, 2016 I'm more familiar with the later HO setup, but I googled some pictures and looks like there is an o-ring where the regulator attaches to the rail. Link to comment Share on other sites More sharing options...
Tanner Posted January 31, 2016 Author Share Posted January 31, 2016 That's what I was thinking but I wasn't quite sure Link to comment Share on other sites More sharing options...
Tanner Posted January 31, 2016 Author Share Posted January 31, 2016 So quick update, the seal comes with the new regulator. So I have that ordered and should be running tomorrow morning. Thanks for your help Link to comment Share on other sites More sharing options...
Marine1Texas Posted February 1, 2016 Share Posted February 1, 2016 yes it is basically a rubber oring. A regulator that is faulty would cause extra pressure, but should not cause the oring to fail. Like any other synthetic rubber life span with gas and chemicals is not forever! However a good time to replace the oring and maybe the regulator. Make sure your orings on injectors are in good shape too. you can get them in a pack from most auto parts store! Link to comment Share on other sites More sharing options...
Tanner Posted February 1, 2016 Author Share Posted February 1, 2016 Yeah thanks! I replaced the regulator. I recently rebuild my engine so I bought some 4 port 5.0 mustang injectors as well Link to comment Share on other sites More sharing options...
