I just swapped the pump in my '99 silverado as a preventative measure. It was a royal PITA.
Spend a couple of bucks and get the Delphi pump; it'll last you another 9 or 10 years. I've heard some of the cheaper aftermarket pumps failing after less than a year.

Thanks for the tip.
I've resigned myself to dropping the tank, that way I won't be so pissed if it comes to it.
But am looking to check the system from one end to the other before committing to it.
Nothing worse than doing the big job expensive only to find it was something relatively minor and cheap like a bad regulator.
