Anybody used these yet? They are a company out of Australia...they come with o-ringed lower inserts like the ffe rails, but the 2 for the secondaries are way different, and im really not sure what size injectors are going to seat properly. Just wondering if anyone has a running setup with them. I would have just bought ffe rails but they seemed to be permanently out of stock on primary rails..

As you can see the primary lower inserts are just like the ffe ones, but those secondaries are vwey different and do not seat very deep into the lim. There's a good 1/4" gap between the bottom of the lower insert and the edge the old diffusers would seat down on to. If I even figured out what injectors to order would this effect fuel flow into the lim?
