I have a converted carb intake on a on-center Stage 2. The injector bungs seem to be poorly installed. The middle runner is lower than the other and that injector sits so low that the O ring barely touches the fuel rail. If that bung was raised the injector would be completely out of the intake tract and shrouded. I have two other manifolds not yet converted and the middle runner on those is also a fair bit lower than the ones on either side of it. Is this a common problem? Is it worth fixing? Should I consider a sheet metal intake rather than trying to fix this? Does anyone have one for sale? Are Wilson or Hogan the best choice?
