My SSR: 04 UV, BOD 2-18-04, SN 5550, lots of polished billet, Superchips, K&N - Previous 03 and 05 owner
The entire assy has to come out anyway so I would just replace all of it. Longevity is hard to estimate, if you keep it above mid level the pump might last longer than if you ran the tank dry due to heat buildup and additional wear but it's really a crap shoot.

I really agree; you have the 7+ year old pump in your hands and it isn't much fun getting it there. Go ahead and replace it as a complete unit.
i would also agree with the 'change it out' theory while you have it out as the service life of the pump is a real moving target with these GM vehicles. They may run for a long time but I have had them fail on many vehicles with only 60 to 80,000 miles on them and result in an expensive tow bill. Pump assemblies can be purchased very reasonable when you are not in a bind, I would suggest that it be done now ahead of the desperation moment.
something that is said as a 'not to do' is to run around town on a regular basis with a near empty tank
there is a school of thought out there that the gasoline in the tank is part of the cooling equation. Now the pump is housed in a plastic cylinder which is supposed to retain a resevior of fuel to act as a transfer of heat away from the pump but just as a measure of caution I think it is a good idea to fill that tank at a 1/4 capacity.

Reason: spelling
If the fuel sending unit is not reading or irratic try a can of tecktron or better yet seafoam fuel additive before the chore of replacing. Sometimes they get gummed up.
In my experience changing out a fuel pump/sending unit the fuel gauge never works properly again!!! Good luck, Rob
There is a bulletin out by GM on the Fuel Sensors. They will help pay for replacing it if it fails. I just had the one in my TBSS replaced. My cost was $130 at the dealer. Regarding Fuel pump: I had the fuel pump fail in my 2006 SSR at around 23000 miles in 2008. So they can fail early..
