Autotech Fuel Pump Internals continue to be the benchmark that imitators strive to reach. However, it is not easily duplicated.
- Each piston (9.8mm diameter) and cylinder in Autotech HPFP kit undergo a high-precision grinding processes many times during manufacturing, ensuring that the most precise tolerances are maintained through the final step. Not the cheapest way to make them but the best way.
- Each piston and cylinder are match-ground and serialized to ensure absolute precision and the utmost longevity.
- Autotech was the first to incorporate plasma DLC coating on HPFP components to reduce friction losses and increase performance. Others have tried to follow by adding a coating to their parts. However, the DLC process alone is not enough, it is not a cure for substandard precision. Â The parts must be precisely engineered for the process to take full advantage. Â The success we have in the field can attest to that.
