Hi AJ:
Rebuilding a Q-jet is a medium size job for an experienced shade tree mechanic and a BIG job and learning experience for a shade tree mechanic who has not done it before. If you have the will, the tools, the shop space, and time you can do it yourself. If not, you will have to find a old school mechanic who can do it. There are also companies on the internet who will sell you a rebuilt one in exchange for yours. If you think you can do it yourself, there will be some downtime on your truck....maybe a week to get it all done and re-installed on your truck. An experienced Q-jet professional mechanic can do it in a day or two. Buying a rebuilt is fastest way but also the most expensive. Either way you go there are plenty of people on this forum to help out and answer questions.
Regards,
Henry
