[QUOTE="TARM, post: 75070, member: 578"] Well you could be returning on less than a 3/8 line and have far less restriction that your regulated pressure. All one has to do is hook up a hose of a given diameter to the pump inlet dumping into a bucket and you will quickly see the what amount of pressure you are looking at. 160 GPH can be handled with a single 3/8 hose. If you think about it whatever you have as the smallest hose size on the pressure side is all you will need on the return size in most cases. Symmetrical hose sizing I guess you would call it. We are dealing with a restriction of less than a total of 3/8 cross sectional diameter going thru the heads at points. So if you can adjust your regulator to drop pressure far below what you plan to run it at then you can see that hose capacity is all you will need for the return. Back to the cooler. No I it should not cause a issue will return flow. When you add up all of those core rows they add up to more than the flow of the main 3/8 in and out lines. To be clear as I do not want to give the wrong impression: There is nothing wrong with running a larger return line. Other than cost and dealing with the size it just gives you more capacity.
