Boy, it’s 4:30, what happened to the day!
I wanted to put a few post scripts fuelled by a few comments I’ve recently gotten putting this manual together:
No, I didn’t make it a total “nuts and bolts” pictoral, listen you need to use common sense, I don’t want the steps to be so detailed you just can’t get through it! I’ve seen some like that! Read the FiTech manual if you feel the need to get technical, I’m interested in installing the system as simple and serviceable as possible. Yes, you can interface FiTech to your distributer… hey but why? You will not get improved mileage or make your teeth brighter…. all that does is make it more difficult to figure out when (not if) something goes wrong.
The diagnostic tree back in the 70’s was using your eyes, ears, nose and hands. You want fuel…. you want fire…. and the beast will run. That’s what you want to look for on the side of the road. The FiTech NOT connected to your distributer can be diagnosed that way. AND if you have to, spray WD-40 down the throat of the throttle body… the distributer fires the plugs and “Bob’s your uncle” it will run. You need this….
Recently there was a Facebook thread on “tweeking a Q-Jet carb”. I have to tell you knowing what I know now twisting springs, bending linkages and turning screws ….. I’m just over all of that. Yes, one of my coaches has a carb. and I may leave it for a bit…. I mean we’re alike in that I have to afford things like this too! But from now on, when a customer tells me they want a reliable coach…. d o what’s needed…. now along with new Timken wheel bearings, a quad bag system, block your exhaust crossovers and be sure you have 30R Ethanol resistent fuel hoses…. you also should consider fuel injection. Now not just any, you want the new, self learning active fuel injection systems we now have. Forget burning chips or looking for a chassis dyno…… unless you want to, I have a good friend with a direct port system. He likes it and wants it, hey no problem with that and if you have a current fi system just be sure you have lists of replacement components, a diagnostic tree for servicing and the knowledge needed to support the system. With that you can call any system reliable.
The FiTech system is by far less complicated and easier to service, also being just out, their support is really good. I will say for the first time I can easily understand and program the system, the price is @ $1000 complete hardware hey and it really looks cool in there
Does it get better mileage, more horsepower, torque… anything? Hey, what’s wrong with doing it because it works better? The fuels today I’m convinced is formulated to be pressurized and squirted out of an injector not sucked through a Windex bottle. We’re not dealing with the same chemical makeup of the fuels, carbs are no longer suited to work. We’ve been “band aide” fixing issues we know carbs have today. I’m done with that too …… fi systems are compatible with todays fuels.
I hope this discussion has helped you understand more FI and the new equipment out there.

Agree 100%! I have two old Porsches with carbs and we have the same issues because of the fuel that is available. With the lower price of these systems these days, it’s silly to continue playing with carbs (unless you have a frend at the airport where ethanol free fuel is still used in private aviation) or are fortunate enough to have access to some of the remaining ethanol free gas stations.
