She's a 2008 Ram 1500 4.7l v8 magnum 4x4. Got it used and am fixing and upgrading things to get it and keep it in good shape. I'm needing to replace an AC line and water pump next. I've read reviews on different (expensive) parts brands but I need honest opinions on what's going to work well and last but is also affordable

 

Rock auto is a good place. Their shipping is expensive though. I normally visit several websites and local parts stores and compare prices.
