This item is not OEM or AC Delco brand. Standard is the aftermarket brand of this multiport fuel injection conversion.

A "cheap copy" I bought on eBay had really stiff tubing...couldn't install it. Question: Is the tubing in your spider flexible? I'm stuck in the middle of the mod with no parts to install.
