Any advice on how to install the lower injector seal on a 2009 ss? I purchased the seal kit ( ES73819) and I can only slide it down the cone about an inch before it stops. I already broke one seal when I apparently put to much pressure to slide it down the cone on the install tool. Is there a trick or did I get the wrong part number? It feels like the seal is way to small... The videos Ive seen doesn't require much force to slide...

 

2173425 is the GM kit.

ES73819 is the Fel-Pro kit.

they could be old stock.

 

Carbon, did the old seal come out ?
