Nice, I didn't get that far.

Thanks! I'm sure that's the problem. I wish it were cheaper though…

I can't say that i have seen that on a NBS before.. Wonder if it was added at some point.

Not sure about the Tahoe but it's on my esky and the Denali too i think. I still feel dumb for suggesting it tho.

Good luck OP hope you get it solved soon

I'll post result when I buy the new pump...

Any word on what happened when you replaced it? Part numbers listed previously show they are discontinued. Does anyone have an updated part number?
