Fuel Pump.. Am I Crazy?

[DSN46]

Out of curiosity James, what have you been feeding those fuel pumps? Brand and Octane?

With my old K5 Blazer (1986) it always got "regular unleaded" (because they only had regular or premium back then) from a Shell station near my house unless I was on a road trip and had to stop at a truck stop somewhere. As for the 02 Suburban it always got fed 87 octane from Quick Trip or Shell... I always try to stay with Tier One fuel if at all possible. Now here is a caveat to both of those. I got the Blazer with 45K miles on it and the Suburban with 60K miles... so I don't know what they were fed prior to me owning them.

Replaced the fuel pump on my 07 Denali at just about 200k. from talking to a few other fullsize GM owners though, it seems fuel pumps tend to die in these things between 100k and 200k. Not a bad preventative maintenance measure to get it replaced at the halfway mark really.

EDIT: also, I replaced it myself and it honestly was not as bad as I thought it would be. I've done break jobs that took longer. Took me about 2.5 hours altogether taking the tank out, cleaning it inside and out, replacing the pump, then reinstalling it.

Thanks! The deed has been done... was done this morning at the dealership. I understand that it is not brain surgery to replace the pump, but I've done a couple and just didn't feel like messing with it on my back in my garage this time.... once I got over fifty years, some jobs just don't appeal to me anymore.
