Thank you for the advice about lubricating the O-rings at quick disconnects fuel line connections.
Bad weather keeps me from vehicle reassembly for 3 days.
I am trying to figure out the signature detail stuff.
I appreciated your experience/wisdom in several posts.
Yes, you are correct.

Since then, I posted numerous issues/obstacles that hindered my progress.
Most issues were due to severe rust / aging causing disconnect delays, and manhandling caused additional $$ component damage.

2003 Tahoe with 5.3 Liter Flex fuel :
Fuel line rusted and dripping just like the OEM brake lines rusted and burst years ago.
I ordered stainless steel replacement set ($200 ) which includes:
3/8 inch supply, in two sections but no fuel filter included
5/16 inch return , in two...
The wiring loom / harness that feeds into the 4WD Encoder Motor 7 pin wiring connector was friction burned/frayed due to the fact that it was riding on the drive shaft.
I cut the black plastic connector away from its loom so as to leave behind 7 cleanly severed ( but way too short ) wires...
I was looking for the disconnect in the wrong place. The disconnect is not immediately at the fuel pump. Rather , it is upstream along the wiring closer to the rear axle. It is a black disconnect plus a grounding eyelet .
1997 k1500 Suburban 5.7 :
Trying to unplug the electrical connector at the fuel pump.
It appears to be a cream colored cube with the wires entering from the side of the connector.
I do not know the technique.
I do not see/feel any squeeze side wings.

Tahoe 2003 5.3 liter with Auxiliary rear heat controls located in the front overhead ceiling:
I am having difficulty identifying the correct replacement part for the Auxiliary Rear Temperature Blend Door Actuator.

Installed the new temperature blend door actuator and followed the recalibration process.
Because ... I received incorrect $40 Temperature Blend Door Actuator from a national auto parts chain (although the Auto Parts spec sheet said " 2003 Tahoe 5.3 exact fit " ).

Perhaps my post was misleading; the issue is only in the rear . The front HVAC is AOK.
I dissected the Temperature Blend Door Actuator one more time because I could not understand what was wrong. Took many iPhotos.
When I edited the photos , enhanced the contrast, made them larger, made...
Before spending $100 for a Rear HVAC Control Module , I swapped the rear seat area (auxiliary) Vent Actuator ( which works) for the rear Temperature Blend Door Actuator.
To my surprise, the Temperature Blend Door moved.
This contradicted my theory that the rear HVAC Control Module...
front heat AOK, coolant AOK.
Rear vents blow only cold.
Took apart the rear passenger side covering to reveal the HVAC system:
Hot coolant gets to heater core and return coolant line gets hot: heater core AOK.

car was loaned to family member and now there is no dash indicator light that normally would show the transmission gear: P,D, Low, N, Reverse, etc.
