Fuel pump is an essential component of a car or other internal combustion engined device. Fuel has to be pumped from the fuel tank to the engine and delivered under low pressure to the carburetor or under high pressure to the fuel injection system. Some fuel-injected engines have two fuel pumps: one low pressure/high volume supply pump in the tank and one high pressure/low volume pump on or near the engine. Two types of fuel pumps are used in automobiles: mechanical and electric. The fuel-injected cars use electric fuel pumps, while most carbureted cars use mechanical fuel pumps. The fuel pump is located inside the fuel tank in most of the cars. Electric fuel pumps can be either low pressure or high pressure. Fuel pumps are rated by pressure and volume.

Fuel quality content monitor is a modular device that uses laser light scattering to detect, recognize and measure the presence of free water and sediment in aviation fuel. It is a prototype device that has completed testing on navy aircraft carriers. It is used as an in-line, real-time instrument that has a ability to detect free water or sediment in JP-5 or DFM fuel lines.

It is robustly constructed in stainless steel with no moving parts to stick or fail in service. It is easily cut to length to suit tank depths from 250mm to 2 metres and is self calibrating at power on. It constantly monitors the fuel for any water contamination and warns if any is found to protect the engine from expensive damage. It is easily fitted in the fuel tank using the industry standard SAE 5 bolt fitting. Up to 16 Fuel Level Senders can be connected to a single network and the sender number is simply selectable at installation by means of the small rotary switch.

Fuel sniffer is a portable fuel dilution meter that can be used in the laboratory or in the field to provide rapid and accurate measurements of fuel contamination in engine oils. It is small in size and ideal for field or laboratory use. It is rugged and easy to operate. It does not require any chemicals and consumables. It needs just over 60 seconds to perform each measurement. It employs a surface acoustic wave vapor microsensor to measure the concentration of fuel in used lubricating oil samples by sampling the headspace in the sample bottle.

Fuel stabilizers are highly concentrated multi-functional stabilizer. It is specially formulated for use in gasoline, diesel and LPG fuels. It contains highly concentrated additives.
