: Our fuel injectors are manufactured strictly for use with high performance engines for racing and off-highway use only, and are therefore subject to the unusual stresses normally associated with this type of use. Since the operation of these engines is far in excess of the safe limits that are usually set for engines, breakage and failures are common, and are an accepted risk in racing. Also, the history of racing has always been one of trial and error by the users of this type of equipment. Therefore, because of the many unknown factors involved in experimentation, and because of the safe limits being exceeded by virtually every part in the engine, we do not offer a warranty of any kind on our equipment. It is purchased and used by the buyer at his own risk and with this understanding. If any of our parts become defective after purchase, the buyer assumes all cost of service or repair.
