I have purchased the exact same Summit Racing fuel rail, Summit Racing intake, and the same DW injectors that Ryan installs in part 10. However, I'm having the same issue that has been reported a couple times that the DW injectors will not fit into the Summit Racing intake. Was a solution ever found for this issue?

Thank you for what has been a great and informative video series and thank you for any help you can provide.

Hello and thank you for watching the series!

So I'm not sure why exactly DW has such an issue with this. I took the injectors out of the box and put them in the intake no issue. They worked great. DW has been less than kind about me saying this. I have no incentive to lie.

I would either get new injectors or if the return window has closed, I would order a bunch of different fuel safe injector O-Rings of varying size and try a smaller size. Just make sure its a good seal so you do not end up with any leaks. Let me know what happens!

Best,
Ryan
