280 Sport Fuel line sizes

[stanton]

I need to know what size fuel lines to run from the tank to the water sep. to the fuel regulator to the rail and the recirc back to the tank.

Thanks guys.

I have 3/8" line from the tank to a Raycor filter , 3/8" out of the filter to a Bosch 984 pump, 3/8" out of the pump to a 10 micron filter under the cowl and 5/16" off the fuel rail back to the tank. No problems here. Remember to use good high pressure line on the pressure side of the pump and standard grade on the return side

Good Luck!!
