Hi Joe,

Can't help you with any spare diffusers. However, I would like to mention something that may save you from busting up any you get and/or incorrectly seating the primary injectors in the block (if you are installing them there).

The primary block diffusers have a small half moon shape key (bump) on the outside (talking about the old 13Bs here not the Renesis) that must be inserted to match the similar shaped depression inside the injector hole. If you do not, it will cause the injectors to set too high with excess force on them and the diffusers when you tighten down the primary fuel rail.

If you shine a flash light into the primary injector holes you will see the depression I am referring to.

Best Regards

Subject: [FlyRotary] injector difusers

Does anyone have any extra injector diffusers for the fuel injectors they would part with. I'm not sure if that is all that is needed. I had a picture that was posted here of the parts, but can't locate it. I tried to contact Bruce Turrentine this morning but the phone number I have has been disconnected, does anyone have a current number for Bruce. JohnD
