ImportantTo avoid personal injury and possible damage to the equipment, always observe the following warnings and notices when using the injection line speed pickup group.
All bare metal locations on the fuel injection lines must be repainted after removal of the pickup group and before the engine is put back into service. If this is not done, the bare metal fuel injection lines can corrode. This could result in a fire if fuel is sprayed on hot engine parts.
Always install the speed pickup group in a location as far from hot engine parts (such as the exhaust manifold, turbocharger, etc.) as possible. Keep the cables and amplifier away from hot engine parts.
Do not over-tighten the thumbscrew on the pickup, tighten by hand only. Use of any tools to tighten the thumbscrew may result in damage to the pickup.
Do not use abrasive materials to clean the inner bore of the pickup contact. Use of abrasive materials may result in damage to the pickup.
