Apologize for drift, but I heard that also. Plus install extra filtration from lift pump. I can tell you changing the fuel filter is a pia for me anyway cause Ive had to pull the fender liner to get decent access to it.Guys I know with CP4's in Dmax's swear by installing a lift pump to take some of the heat of the CP4. I have no personal experience with this but it seems to be a very popular add-on and they say it works well. Just throwing out what I've heard.
