I'm wondering if you need a special crush washer on the side with the large opening? It looks like you need something to keep it centered. I spent $135 on this thing. I don't want to put the banjo bolt back in. TIA

 

Ill be installing mine within the week. I bought the 2 seals that Maxdatrix offered. Not exactly sure why 2 are needed. One say from fuel rail, the other from Pulsation Damper... But yes, it looks like one is a normal washer seal and the other is a larger washer with teeth to the inside... Not 100% clear on the install though

 

That makes sense. I wish I had known that I needed that fancy washer. Thanks
