I've got about a $1000 saved up and am wondering about the rasp. I bought my truck with 90k on it from a dealer. They used the truck to do dealer transports. They replaced the vp44 and lift pump at about 80k. Only thing i've done is install a pressure gauge which I keep a close eye on. I realize that I could replace the lift pump multiple times for the price of the rasp. Any thoughts on the pros or cons are appreciated.
