AirDog

Driving a diesel pickup and want a more consistent fuel supply? AirDog makes lift pumps with air and vapour separation for diesel engines, so the injection system gets clean fuel without air bubbles. Here you’ll find complete pump systems, filters and accessories for many popular diesel pickups.

Fuel systems developed for diesel engines

AirDog is an American brand from PureFlow Technologies that specialises in fuel systems for diesel engines. The idea is simple: diesel fuel can contain air, vapour and contaminants, which can cause an uneven supply to the injection pump and injectors. AirDog systems are therefore built to remove air and vapour, filter the fuel and deliver steady pressure. The brand is especially well known among owners of American diesel pickups from Ford, Ram and GM, for daily driving, towing and added power.

AirDog’s key products

The core of the range is the lift pump systems that sit between the tank and the engine’s fuel system. They combine an electric pump with a separator that removes air and vapour, and a filter set that catches water and particles. The systems come in different flow sizes, so you can choose based on whether the truck is stock or has larger injectors and more power. AirDog also offers replacement filters, install kits, tank sumps and other spare parts to keep the system in good shape. See each product for vehicle fitment.

Frequently asked questions

Why is air in diesel fuel a problem?

Air and vapour in the fuel can cause uneven pressure to the injection system. This can affect how the engine runs and put strain on the pump and injectors. A lift pump with a separator is designed to remove the air before the fuel reaches the engine.

How often should the filters in an AirDog system be changed?

It depends on use and fuel quality. Follow AirDog’s recommended interval in the instructions, and change them sooner if you often fill up at different stations or drive in demanding conditions.
