Boomba fuel rail issue

[Gslocum]

I just installed a Boomba fuel rail, but it seems like it was made for longer body injectors. Im running plug and play FIC 725s, which are stock body size, and they seem to slide back and forth between the intake manifold and the fuel rail, even when the rail is bolted down. Did boomba make their rails only for long injectors?

BTW, i've gently run the car and i havent noticed any leaks, but I don't want to pump 70psi through the rail to find a leak, either.

Did the 725s have the little plastic retainer on the tip that holds on the bottom o-ring?
