Hey guys. I ordered the fast injector spacers. They came with new O-Rings. I installed the O-Rings on the spacer and now i cant get the spacer into my LS6 intake. Should i stop being a Nancy and force it in or what is going on?? I don't want to pinch or rip the O-Ring but if it is necessary to use more force i can.

 

Did you put any oil or petroleum jelly on the rings? It should be snug. It has to seal 60-80psi consistently.

 

WD-40. Oil or jelly would be better to use.

 

WD40 isn't really a great lubricant. I've always used oil.
