i just did a comparision on 2 pumps cause i had them i use the jabsco pump in stock location definatly plug and play says it flows 3.5 gpm if i am correct i didnt like the flow of it could barley see the water moveing in the upper cooler so i switched to a flo jet 3.2 gpm under the hood a little more work but damm this thing flows i would recommend doing a better pump than in the stock location you can use the same stock wires for the stock location under the hood drivers side is the harness green oragne and black you can tie in right there even with stock lines would only take mabey 10 min to have the pump hooked up i love the flow jet it works like mad and you can get it for 65 bucks at any camping store
