Edelbrock 500 rebuild kit?

[Mac]

Even though the instruction sheet says that the accelerator pump cup is not included in the kit, I found what sure looks like a cup and related pieces to install it on the plunger shaft. The new cup is blue in color and some surfing the net tells me it's Viton (Woo hoo, ethanol resistant).

Has anybody else run across this and are these other pieces a new system for retaining the cup?
Thanks

Since you guys were zero help (lol) I called Edelbrock Tech and was told "Oh yeah, we're throwing the alky resistant acc. pump cup in the kit now" and " yeah, the instruction sheet is long overdue for update"

Hope this helps somebody else.

Thanks for the info Mac.  I have a carb I need to rebuild and it's nice to know that they're upgrading for alcohol resistance.
