For anyone interested, here are the price quotes (High?!?!) from my dealer today. The reason for my visit to the dealer (other than having a day off), was that I've had a problem with my gas gauge. I already had figured out from this forum that it was the fuel sending unit, but I wanted a quote from the dealer to replace it.
They read the following codes: P0464, P0463 and P0401.
New fuel pump w/fuel sending unit $882 (Note: it would be about $100 less for just a new fuel sending unit)
New EGR valve w/gasket $447
Clean the EGR passage tube $94
Anyway, I nixed the whole plan from the dealer.

I'm sure my EGR just needs to be cleaned (I've never cleaned it before) and I'lll do that soon, myself, thanks to the instrucitons in this forum! I'm going to live with a bad gas gauge, 'cause it's just an annoyance and the fuel pump is fine. I do need to investigate how long a fuel pump typically lasts.
Here's my info...
