Anyone have a set of these things they'll part with? I'd rather not have to pay $9 each.

Is there any substitute?

I used regular o-rings and stacked them until it was appropriately set.

What injectors are you using?

Search Advance auto, they sell them as a set, EDIT found them P/N 158-0431.

Injector O-rings for an 88 ford ranger 2.3l they are nice and thick use just one per injector..I had the same issue and didn't want to spend that much for oem replacements. Work and seal like a charm. And yes I am talking about a replacement for that upper left part.

I bought mine from Advance Auto. Beck-Arnley makes them.

Yea man i lost mine to when i built my motor...11$ a pop over here my cost fucking brutal.
