That little black plastic oval thing? it's a spacer to keep the injectors lined up correctly in the rail. I "suppose" you could fake it with a couple washers... It would be even better if you still have your old one.

I am going through the same ****. Believe me, it's not worth it to rig something up. I did that and gas was leaking (very bad thing). I decided that the best and safest thing to do was go to Mazda and buy the OEM stuff. It cost < $4 each. Jay
