Had A question this morning.I'm changing my fuel system from Tbi to Mpfi.The system I took off was a mercruiser system and was a returnless system. The system I purchased from Marine power is a returned system.I was going to run my line from the tank to the cooler then to the filter housing then to the pump and up to the rail.The problem comes in on return.Would I be better off going back to the tank with the return or to the filter housing.Idon't know which is best.
Thanks for any help
Doug

Best is back to the tank if you can and the easiest is to the filter/separator.
