I'm slowly working on a 6.0 swap in my 2005 1/2 ton. I picked up a used TBSS intake manifold from Craigslist. It was complete with the throttle body, fuel rails, injectors, and most of the PCV and EVAP hoses.


I was pulling everything apart to clean it and check some things, and I noticed 2 of the injectors have some type of adapter and gasket in the plugs, but the other 6 don't. Part number on the injectors is 12580681.


Anyone know what these are and if I need to get them for the other 6 injectors?





This is what the other 6 injectors look like without them.





They just slip out really easily.

 

I think that's actually just the seal from the injector harness itself that popped out. I have had them stick in the injectors like that. Just remove them, your harness should still have them in there.

 

Thanks! That's what I needed to know.

I got a little worried since the harness in my 2005 will have the mini Delphi end on it and wouldn't have the right seals, but I looked at the adapter I bought off eBay again and they came with the seals in them. Looks like I'm good to go with the injectors.

 

Actually looks like a broken connector, but as stated just take them out

 

Free spare seals!
