We Service fuel injectors! We take your injectors and do before and after flow testing. We do a leakage test, spray pattern test, ultrasonic cleaning, replace the O-rings, pintle caps and injector screens. All injectors are numbered when you get them back so that you know which injector is associated with it's corresponding data. All for $18 per injector. Turn around time is usually 1 day after we receive them. Return shipping via USPS priority mail. Our shopping car will not accurately calculate shipping...return shipping is a flat $8 for the entire set of injectors. You can mail your injectors to us at PO Box 130, Odenville, AL 35120. We can take any major credit card by phone or you can mail us a check or money order along with your injectors.
