[QUOTE="psduser1, post: 96480, member: 735"] Dennis, Tarm, thanks to both of you for your replies . Both well thought out and explained. The links Tom posted above is what I read before, and is what is contributing to my confusion, somewhat. I know that cooler fuel makes more power, seen the numbers firsthand on a dyno. Not huge gains, but still there. Having said that, I would agree that the basic design of the 7.3 makes a cooler on the pressure side almost useless for strictly making power purposes. I'm more interested in maintaining (controling) temps at the tank for pump life and so forth. Granted, I've gotten pretty good life out of my current pump, and is like to continue that. Now that the fuel is returning from approx 210 deg heads, Dennis, your saying its a nonn-issue, based in x mi. of service. I can see the logic there. Thats the same lofic im using when I lean towards dual stock pumps as opposed to a Fuellab. However, Tarms points about lubricity and viscosity are directlh related to that same service life. Theres just enough info to bug me! iI think Ill run something for a cooler, not sure what yet. The biggest reason for changing my fuel system around after all is reliability. [/QUOTE]
