Fuel Supply

Many engines suffer from a poor fuel supply at full load. The fuel pressure breaks down; the engine runs too leanly with a full boost. The exhaust gas temperatures rise to over 950°C, something that can actually lead to the melting of the piston.

In our shop, you can therefore buy all parts required for a top-notch fuel supply with gasoline and diesel that prevent the mixture from being too lean. We only have high-quality components for Volkswagen, Audi, BMW, SEAT and many other car brands, e.g.:

Matching Components for the Fuel Supply

The components of the fuel supply system should be matched to one another. Injection nozzles that are too big or a fuel pressure that’s too high can also cause damage to the engine. Increasing the fuel pressure with a fuel pressure regulator should be done only for fine tuning, because doubling the fuel pressure brings no more than roughly 25% of the flow rate. Increasing the fuel pressure from 3 to 6 bar, for instance, brings only approx. 25% more throughput. In such a case, you should install larger injection nozzles in your car.

Top-Notch Accessories for Your Fuel Supply

Our range of accessories for fuel supply is of absolutely high quality and perfect for engine tuning – for all car brands, from Audi to VW. The Aeromotive A1000 fuel pressure regulator made of billet aluminum, for example, is designed for a performance of up to 1000 hp. Its setting range is 0.3 to 1.0 bar. Our own plug & play fuel pump for 2L TFSI engines is ultra suitable for high performances of up to 500 hp. It improves the fuel supply of performance-enhanced engines, especially in cornering. Our pump is as large as the standard part but significantly more powerful. It can be easily installed by plug & play.
