Fuel Pressure Regulator vacuum line part number

[stagrlee]

Having a hard time finding the right part number for my fuel pressure regulator vacuum line. Its a 2004 L59 5.3L Tahoe. Its part number 1 in the following diagram.

 

 

 

 

 

The parts lookups I'm getting (wholesalegmpartsonline and similar) are giving me GM 17113556 which is the wrong line. That line is for the fuel pressure regulator that has the vacuum port facing upward. The Flex fuel pressure regulator points outward to the left fender. on the flex motor. You end up with part number 8 (below) which doesn't fit the Flex motor. Anyone know the right part?

2004 had returnless fuel system and the regulator is on the meter in the tank. Check if your truck has #1 Flex Fuel and #2 two fuel lines, if it only has one it's a returnless system. My 2004 5.3L is.
