I am trying to replace the fuel pump connectors (the fuel line ends) on my 2000 Chevy G3500. I've been to Carquest; they sent me to the dealer. The dealer sent me to Carquest.

The connectors are quick disconnect fuel connects. They're something like part no. 800-163(1) at the bottom of page 332 here: http://www.dormanproducts.com/catalo...Disconnect.pdf

One is straight and the other is a right angle. Anyone have any idea what the GM part number is for these?

 

They are not serviceable with any parts from the dealer, you must replace the lines. The Dorman ones in the picture are to be used with a special tool. Shops that have it by the kit like the link below. Then order replacement pieces as the are used. You can not do it without the kit as the piece is pressed into the plastic line.
