Hey guys - I bought a 99 Z71 with the 5.3L and 4L60E. It has the push
button 4X4. It had 75K (miles) on the clock and now has 120K. I've never
had any trouble at all but I'm wondering about the fuel pump and the relay.
I'm about to put 4,000 miles on a trip. It seems that most folks say the
pump on chevy's last about 100K. So should I change a good pump or wait
until it makes me walk? Thanks for any input!
