Default cold gas/hot gas?

I heard that hot gas isint good (like when the fuel line goes close to, or around the engine head). same concept with dirtbikes. cooler gas = better... so....

if I put the niromethane into the fridge before I ran it would it work better?

I've heard cooler fuel is denser, so better mileage. I have seen guys(and also do it on hot days) keep their fuel on ice.

One problem cold things moisture and that it warms up in the tank. The other thing when fuel is atomized it gets cold.

I put my fuel jug in a couple plastic shopping bags, and put it in my cooler on race days. Make sure the bottle is sealed up really well, you don't want any water being absorbed by your fuel. I'm not sure if it does anything at all but it makes me feel better.

In the fridge? Never heard of it but you have a chance it attracts watermolecules to it espcecially if it is already blend with methanol. Methanol attracts water, that is why we boatracers flush our engines with WD40 AND afterrun oil so there is no corrosion. Especially in the bearings.
Now back to your question: you have to look for yourself what length works for you for the pressureline. Too long results in less pressure which results again less fuel to the carb. Keep it short, not too short. For the fuelline: don't twist it around the head but straight from tank to carb BUT not too short! Exact length depends on engine.

The engine runs at 200+ that's gotta heat things up under tha body. The fuel in the tank is going to heat up and if the cold fuel is dnser then it will tune differently. I think keep it out of direct sunlight and run it at ambient temp.
