Is there a difference between an obd1 gsr fuel rail and a itr fuel rail?. I recently installed a 00 itr head and a itr intake manifold on my b18c1. I tried to install the fuel rail and there was no room for plastic insulator washers that go between the rail and the intake manifold. I thought all b series fuel rails were the same, but evidently not.

 

bump. bump.

 

I ordered a gsr rail on ebay. I went to acura trying to get those spacers (manifold to rail) and found out that they weren't needed on the itr. Anyways it fit perfectly. My tuner said it was a itr rail. I'll post a pic tomorrow.
I'd like to know too. Bump for this guy.
