2010 6.0 Fuel Pump Replacement

[97whitez71]

It's a 2010 2500hd 6.0 LTZ with 166,000 miles, long crank times to start after sitting.  VIN 1GC4KYBG2AF137816 , L96 and it's a crew cab with the short wheel base.  Everything I read points to bad fuel pump.  When I put my VIN 1GC4KYBG2AF137816 into ACDelco, it gives me several fuel pump options.  Based on my information, it points to part numbers MU1860 or M10216.  It appears MU1860 has everything but wanted to get some other opinions.  I figure while I'm in there, I'd like to go ahead and replace everything I can.  My questions are:  1. Is there a way to know which part number I need without having to remove the existing fuel pump assembly (this is my daily driver)?  2. When replacing the fuel pump assembly, is this the pump, fuel filter, regulator, and sending unit in all one assembly?  Or do I need to order any of that separate?  From what I can find searching the internet, this is all in the tank now versus the older trucks.  I appreciate the help and responses.  If I'm missing anything, feel free to let me know.  Thanks!

I bought the whole assembly from my local parts house on an 06 (about $140).  Every part needed is in the assembly.  Sorry i don't have the part number used readily available.  Very straight forward and easy to install.  I ended up just removing the bed. It was easier than dropping the tank, plus you don't have to worry about how much fuel is in the tank.  Hope that helps.

MrBullz, was that an ACDelco pump or another brand?  How long has it been since you replaced and how is it performing?  The ACDelco pump is $260 at O'Reilly's.  Thanks!

It was an ACDelco.  This was in my mom's silverado about 5 years ago and it is still running like a champ.  I messed up and bragged to my uncle that i could do it and replaced his with the same pump from the same parts house and that was probably 2-3 years ago.  They seem to go out after around 150k miles.  The first indication is the fuel gauge intermittently stops working.  My daughter has an Equinox and her fuel gauge quit last week so I guess I will be 3 for 3 soon.
