GM Delco part.

This is for the TBI 88-92 or carby version V8.

     Due to the fuel pump being a pain in the butt and wallet to replace.. some people have gone ahead and made a youtube video's on changing the pump. This is one of them (copy and paste this into a new separate page)

Not a fun job this... 

Smarter way ongoing would have been an access hole for servicing.. like this..on the hump of the hatch diff area.
