If you use the 6mm stiff tubing that is supplied with the UAT there should be no problem with about 18" upstreamfrom the pump. I have been doing that with a Titan and have seen no problems. Down stream after the pump i run the 4mm to the motor and can be any length. I have always installed the small jetcat shut off valve as close to the motor as possible, it helps to keep lines full for the next start and also if you have to remove the motor it holds the fuel in the lines.

your right in all means , however as i mentioned the acceleration can cause a cavitation.
ans some accelerate 4 times slower then a Rhino or Merlin.
