I'm installing a Magnum 1.20 into a CG Ultimate .60 and I'm considering using the fuel dot method to avoid removing the cowling each time I fuel or defuel. My question is, does a four stroke 1.20 like my Magnum require any particular plumbing besides the normal 3-line setup? (1-fill from dot, 2-feed to carb, 3-vent) Thanks for your consideration, and please don't answer if you haven't actually done this.

THe Magnum is normally aspirated so just use your normal system.

No, the Magnum 1.20 is not pumped. Sounds like the 3-line deal is the way to go.

On your 3rd line, the fill line, you might consider putting a second clunk on it, making the de-fueling easier.

If you don't do this, bend the fill line down to the bottom of the tank. You'll have to twist all the brass tubes the same way to get them in the tank, then twist the fuel-de-fuel line down after it's inside the tank.

Get a Dubro refueler. It connects between the carb and tank on the fuel pick up line. A one way valve is operated once you connect your refueling line to it, so stopping fuel going to the carb.
