Fuel Chilling System?
Whats up with this? Do you really see extra gains from cooling down your fuel?

Design Engineering's next generation method of chilling the temperature of fuel before entering the intake stream - the CryO² Fuel Chiller System!
The new CryO² Fuel Chiller System uses the cryogenic properties of liquid CO² to charge a series of internal cryogenic chambers surrounding the center "fuel" chamber. As the fuel passes through the center chamber, the cryogenic-charged chambers super cool the fuel by maximizing the thermal transfer process removing heat four times more effectively than any other system available today.
As the temperature of fuel is reduced it increases in density. The denser fuel results in better and more efficient burning of the fuel - consequently generating more power and greater fuel efficiency.
Under hood heat created by high pressure fuel pumps, headers, exhaust manifolds and other heat generating components all combine to raise the temperature of fuel and creates a potentially lean condition or “vapor lock” that can damage the engine.
The CryO² Fuel Chiller System can be used along with your existing CryO² system, or a nitrous oxide system, to lower fuel temperatures and improve HP and efficiency and reduce the chances of engine damage.
Each CryO² Fuel Chiller System comes complete with two (2) -4AN and -6AN fittings as well as two (2) 3/8” barb fittings and mounting brackets and hardware. Also in the kit is a 2-foot length stainless steel braided hose for use with -4AN fittings to allow a connection to other components such as a CryO2 Air Intake or CryO2 Intercooler Sprayer.

Features & Benefits
- Removes heat from fuel greatly improving fuel density
- Super cooling efficient design maximizes thermal transfer process
- Reduce chances of detonation
- Cooler fuel reduces chance of lean condition and vapor lock
- Utilizes DEI's CryO² system or existing nitrous system
- Lowers air & fuel intake charge temps improving horsepower and efficiency
- Easy install

Don't need it. LPG is already quite cold 
Apparently you only get a 1% drop in volume per 15°C drop in temperature. Not a lot aye?

Vapor lock is a problem for carburetted engines or cars with other, severe problems underhood.
The name of the system makes me think it uses either flowing Carbon Dioxide or dry ice, either of which will need periodic refilling, or else it is a total scam. I lean toward the latter.
I did a little looking around and it seems that you can cool the intake air charge (slightly) by using colder gasoline, but any power increase on a car with just a couple hundred horsepower will be "in the noise." The increase if any would be more than offset by the cost of the cooling system . . . and probably using a different dyno or having different ambient conditions on dyno day would make a bigger difference (by a lot) than using this type of thing on a small four-banger.

Even if it would work - I don't know how trustworthy the info on the site is - you do need the tank and installation kit PLUS this fuel chiller. The prices on the site are not really in favor of installing their gear ($390+$340 = $730). But there is a potential increase in hp due to the decrease in fuel volume and cooling. I don't see this being effective enough to warrant the purchase of only this part of their system. The combination of parts seems more interesting regarding power gains - but still a bit too expensive.
