This is a technique used to partially or completely remove the use of air pressure in the Fuel, Solution Tank of Fogging machines. The air pressure from engine is used to pressurize Fuel and Solution tank. This pressurized air forces the Fuel towards engine. Thus after pressurization of tank, separate supply pump is not necessary. Now a days tanks are made up of HDPE, Aluminum etc. which can explode on excessive pressure. To overcome this pressurization problem Tanks can be installed above Carburetor and Engine. Also, Fuel can be supplied to Carburetor by capillaries with multiple point fuel injections.
