Ishiftem, your story goes contrary to dozens and dozens of them that go the other way. But the difference is that the pump you were using
doesn't move enough volume to support a return system, if you had used an in-tank TBI pump, you would most likely have had no problems. Also, the return should have been -6, there's really no need for it to be the same size as the feed line. Just for example, no OEM system uses the same size for feed and return, virtually ALL of them are 3/8" feed and 5/16" return.
And one major major plus to a return system, cooler fuel, and as a result, no vapor lock, which can be a
huge benefit on a street driven vehicle, especially a daily driver.
