:help: I realize that the duramax's don't have lift pumps. I am thinking about adding one to mine to help out fuel transfer in cold weather. this is the first diesel I've owned that didn't have a lift pump and am finding it is alot more sensitive to cold weather than my other ones were. I think a lift pump would help an am wondering if any of you have installed one, what kind did you use and was it as easy to do as I think it should be... also will this cause any warrenty issues..

thanks... loving the truck...:grd:
