Hey.. that's right. Good idea.
.. my thoughts on the Chevy fuel systems:
The pump on the later years is in a submersible bucket ( 98+ I believe ) that is meant to help cool the pump. These pumps are cooled internally and externally in the tank - it is very important to not let the fuel get below a certain level.
I have replaced both the early and late fuel pump types across a few different models, ie. silverado, trailblazer, s10 truck, s10 blazer, suburban, etc.. I only use the AC delco parts for replacement, nothing else. My Chevy parts guy in Texas tends to get me around the same or slightly lower prices on OEM than the local parts stores for aftermarket - no warranty, but I havent had a "repeat" failure either.
I have had to replace the sending units for the fuel level floats also - the ones made before 07 had tiny wires on the contacts that could possibly get bent out of shape ( I dont know how they physically bend, just that they dont work after this - and on some of these later models it causes a Check engine light also ) These tend to cost about $100 where the whole pump module w/ bucket and new level module, etc .. is a little under $400 including the filter and shipping.
The last chevy pump I replaced wasnt exactly "bad" it was more along the lines of our dying Ford ones - it had a bad check valve or the internal mechanism wouldnt hold pressure .. ie; when you crank it, you had to crank and crank to build fuel pressure to start, when you let the key go, it went back down to 0 PSI. For the longest time the customer put it off until it started cutting out on the freeway at higher speeds - new pump fixed the hard start condition also.
Injectors - about 20 years ago these were replaced all the time. Not so much nowadays, the number of injector replacements have gone down significantly, especially in states like California where fuel is regulated ( California law says that all fuels need detergents in them ) .. my thoughts, use Fuel injector cleaner if your state does not have fuel regulations in place. Otherwise, fuel injector / system cleaner is a waste of money in California. I honestly never have had to replace a single fuel injector unless it was to upgrade to a larger #
.. like I said on the Fuel pumps, the last replacement I did was on a Turbo Volvo. First, the kid drives the car - the Oil light comes on and never puts any oil into it. The engine develops a rod knock, so I fixed that with a new engine. Then he runs out of Fuel. It was completely empty, puts another 2 gallons in, wont start. no fuel pressure .. bad fuel pump. My thoughts .. he cooked it running it dry - I didnt physically take the motor apart, just tossed it in the trash and went with a brand new replacement.
But yes I do believe that maintaining a constant supply of fuel in your tank is critical for the life of the pump itself. But the Chevy ones are typical to go bad before 100k miles whereas most Fords (Walbro) last well over 150k
