if i remember right around 72-73mm with 11mm oring

 

We have some aluminum sleeves made up that will allow you to run a 14mm o-ring on the rx8 injector rather than the standard 11mm.

 

i am interested can you post up some pic

 

Here is a picture showing it fitting just as described previously.

Middle is the injector as it is in the RX8 (11mm o-ring w/ shorter grommet)
Right is with the previous linked parts
Left is fit snug in the rail made for a 14mm o-ring with the taller upper grommet to stop it from not seating in the bore.
Rail is adjustable in height...
What wrong with my solution again?... without explaining it with a picture of 11mm o-ring trying to fit in a rail made for 14mm o-ring??

 

you are the first person that i heard of doing this

personally i wouldn't do it that way i think thats a setup waiting for a disaster

i wouldn't be surprised if under high pressure that o ring got pushed down

especially under high boost

11 to 14mm spacer this would be better solution for running 11mm injector in 14mm rail with taller grommet

this will let you run the injector with original 11mm o ring in a 14mm fuel rail

personally i wouldn't do eather of this solutions...i gave up on rigging 14mm rail long time ago

i would have a proper rail fabricated

there is couple of shops offering custom fuel rails for around 150$

Karack - posted that he could fabricated them

 

This is the rail you are talking about needing. Primary Rail to accept 11mm o-ring Injectors, right?
