LynMar Posted 3 hours ago Share Posted 3 hours ago Hello all, I’m new tho this forum, also I’m new to truck, I recently purchased a 2000 Mack RD 688s. Under one of the injector bases has a fuel leak. I check the bolts and they are very tight. Can someone tell me if there’s a gasket or Oring that need to be replaced?
