You wouldnt want to use a hemostat such like Darock. Sounds like he only does it to divert the overflow from going to his muffler because of his particular muffler as it would have to fill with fuel before overflowing.
Nope. The hemostat keeps the fuel that's going into the tank going into the tank. The fuel going into the tank sees two paths. One into the tank and one into the open muffler. It goes both ways equally, unless the hemostat closes the line into the muffler. Uniflow systems usually are filled from the hoses that go into the bottom of the tank. Those would be the pressure line and the pickup line. I happen to T the pressure line for fueling.
