I got a set of 780cc Siemens-Deka Peak and Hold Injectors the other day and when I tried to install them the top part of the injector doesn't slide in to the AEM fuel rail cuz it is a little too big.

Is it always like this when you upgrade to injectors this big? or do I need like a different type of fuel rail? or do I have injectors made for the wrong car?

By the way they are going in to a GSR

 

I dunno why but Siemen injector just sounded really funny to me...

 

Im using Dekas, but w/ the stock rail. Fitment was tight, but needed to use two oem injector seals each on the rail end.
If they dont fit, then just make the holes in the rail bigger.
Got a drill press? or take them to a machine shop and explain what you need.

 

Ok, thanks man...Do they actually make direct fit injectors for hondas though?
