    one gallon may be pushing it a bit.

    about 1/2 gallon. then you find yourself at a place like dexter where you have to drive to the rope and back to the outramp, takes a bit more. but even with that little amount, i'd be concerned with vortexing the suction in a 1 gallon tank if it gets low.

    Never measured but i'd say the 405 uses less than a gallon on N20.... No sure about the 418 but seems about the same... Stark or RJ might know for sure. I'd say about a half to 3/4 of a gallon on N20

    X2 I would shoot for a 2.5 gal tank and be safe. Last thing you want to do is find out it wasn't enough with a single gallon.

    I would think a 1 gallon tank is smaller than advisable. There are to many what if's involved. What if you are given the Ok to start your motor and for whatever reason it starts hard, you have now pumped it several times, but it starts and the motor is running. At the last few seconds before green light, the course is red lit for one of many reasons, you now go through the process again for your run. you have a problem.

    I assume there is a good deal on a 1 gallon tank or you already have one, but it is smaller than practical. Don't consider it for weight as fuel weighs about 6 pounds per gallon and the most weight saved would be 10 pounds.

    Weight is the only thing to consider here...10lbs is alot...if I wasn't worried about weight then tank size wouldn't be an issue

    Have the tank sumped, for a little better low fuel delivery, and capacity.

    I run the small imco. Its a 2.5 gallon with an ice tube that takes away space from the fuel capacity but adds weight from the cap and tube inside, and I just about never use the ice tube. Except in really hot weather. One pass at firebird uses noticeably more fuel than at Ming, considering the longer drive to the out ramp. Truly a 2.5 or 2 gallon tank would be cool. They don't weigh much especially the spun aluminum IMCO ones.

    I think Mudpumper is pretty close on the bottle about 3/4 of a gallon.
