Gday, I'm hoping for some help. I've fitted ID1000 injectors with the blue Top Hat adapters, into an Aeroflow BA/BF billet fuel rail. Problem is, the o-rings on top hats dont seat into the fuel rail far enough, so I have fuel spraying out from between rail & top of cap. Top hat o-ring sits about 1.5mm into the fuel rail. The purple Top hat adapter caps look only millimetres longer, so dont look like they will seat right into the rail either. ...and the standard long length tapered adapters (for 1/2 size injectors) are too long. Has anyone else run into this issue? Cheers!
