WitchHunter Performance can clean & test most all auto, marine, and motorcycle fuel injectors.A look at a few of the many types of Fuel Injectors we service. |
|
Bosch top feedProbably the most common type in use. Fuel goes in the top and exits out a single hole in the bottom. Most have a high impedance coil and uses a tapered needle (pintle) that seals into a tapered seat until energized. |
