friends i just had to post this my fuel pump had quit working so i installed a new one and my car seemed great but for years i have had a ticking sound close to my fuel regulator under the valve cover well i bought a used ccrm box and was just checking it out on my cobra to see if it works well the car started faster and ran smoother,so i took that box off and installed my old one soon as i did my fuel pump would not kick in so changed back to the newer ccrm and all i can say is the tick is almost gone and at times it goes away my car runs like a wild cat on steroids she pulls harder even gets sideways when i get on it off the like i am one happy camper
