Hey guys I know I know this subject has been covered already but not in much detail here is the sketch.
I bought a 04 yukon denali 2wd with the awesome 6.0 it runs everything works I know its basically an easy swap from what ive researched im putting that engine in my 03 silverado single cab that came with the punk *** 4.3 only question I have is will I need new fuel lines? Aswell as a bigger gas pump? The one in the denali went out. Any help and advice would be awesome!! Thanks

 

gas lines and pump will work fine, youll probaby beable to get away with using the yukon motor/frame mounts also. just swap it all over it'll work

 

Alright I was making sure because I read in a thread that the v8 has a return fuel line and the v6 doesnt or some **** like that ill link it here when I find it it was from this site itself.
Yea should be easy i will start taking it out tomorrow the tranny mounts up the same right? Or do I need new mounts for that as well im taking them both out in 1 piece also will I have to get a different drive shaft?

 

nope your trans will bolt up and driveshaft will work
