After looking into a economical solution to fuel injectors I've come across something interesting in regards to fuel injector modification. (not flow modification)
Below you have a standard Siemens DEKA 625cc injector that fits a "domestic" style 14mm rail
and here you have the same injector but has been modified to fit an 11mm rail.
Has anyone attempted this modification before or have any insight on it. Doesn't appear to be to difficult but you never know.
