I recently bought 1000cc grams injector and I'm having an issue with having them fitting. It seems as if there to short cause when I turn the key to prime the engine gas start spraying everywhere. I am using the RBC manifold

 

Got any pictures of them installed? I have Grams 550cc injectors and have had no problems with them so far. Either you bought the wrong injectors for your motor or the fuel rail isn't on correctly. Also check to make sure all O-rings are installed and seated correctly.

 

 

Looks like the injector isn't fully seated. Try taking it out and see if anything is in its way.

 

Are their o-rings on them?
