5.7 vs 6.1 Injectors

Anyone know offhand if the dimensions are different between the factory 5.7 and 6.1 injectors?  I went pretty closely back to stock, and I could've sworn I saved my old 5.7 injectors, but all I could find were some factory 6.1 injectors.  They seem to work well enough at first, but eventually the number 8 injector (closest to firewall on passenger side) will break the seal and start spraying fuel in the engine bay.  Changed the o-ring and it still did it eventually.  Maybe the 5.7 injectors are a touch taller?

That's a real possibility. The factory rails have been living in a box getting thrown around and went through a big move.  I'm going to pull it off and check.  Thanks, Guy.

Yep. Looks like the last port was bent a tiny bit out of square with the rest of them on the fuel rail.  I was able to bend it back, we'll see if it stays sealed up.
