Ive searched for awhile and called ray. I am trying to figure out what this part number is?

It is the O-ring on the rail in question. This isnt the Insulator correct? Ive looked on the FSM page for the fuel system and it lists the air bleed socket and insulator and i didnt see this on there.

Im sure this is an easy part number and am just overlooking it.

Thank you for your help. I feel like a noob.

 

Yes if my memory serves right that is the insulator. It insulates the heat from the fuel rail (although not very well).

 

alright good. Just wanted to double check. there are only two insulators on the primary correct, part number ending in 257A
