you must have "pump rub". it rubbed through and spewed fluid everywhere huh???? search google for duramax pump rub kit, fix your existing one with the parts and never worry about it again
No it just rotted away I will try to take pics. How do you tell if it is a hd or a xhd. I know it's a 263 but they offer different versions. If I had to guess I would think the 263 xhd came behind allisons ?
