2008 Mobius LSV with Indmar 340 | Fuel Injector Testing

[Jhendrix39110]

I bought this boat used in 2015, and haven’t done anything with the fuel injectors. I would like to test them individually to see if any are clogged or not working. How do I remove the fuel rail? I found the 4 screws that hold the rails in place but I can’t access them with the plenum on. I removed the 6 Allen screws in the top of the plenum but the plenum is still firmly attached. Any advice would be appreciated.
