Just got the bad news! LB7 injectors! Looking for price confirmation...

[stilly]

Well, I did what I could to hopefully avoid what appears to be the inevitable, but my 2002 LB7 injectors went to hell (93k miles). Aside from the typical symptoms of bad injectors, the shop tells me the everything is rusted and shot (Chicago truck for one year). They're quoting me two prices, one for OEM and the other from "their parts dealer". Here's the quote:

OEM, Shop Parts dealer
8 injectors: $3200, $2860
2 return fuel lines: $168, $168
8 fuel lines: $927, $732
O rings: $49, $49
Return line gasket: $21, $21
valve cover gasket: $130, $130
Labor ($95/hr): $950, $950

Total (before tax): $5445, $4910

So, bottom line: Is this in the ball park?

OEM or their parts?

Is there anything else I should be doing while they're in there?

Thanks in advance. JIM
