Has anyone converted from carb to FI, what are the pitfalls and advantages to doing this?
Thanks

VW did it on all of their models in 1968-75.

Most people I see have moved from FI to carb because they are unfamiliar with the FI system.

Advantages: Better mileage, starts quicker, runs better overall (no fine tuning of carbs etc.

Pitfalls: Owners that don't know how to diagnose any troubles with the system, the cost of conversion. Get a Bentley if you are going to do this and if you can find a car with an intact FI system to transplant that should lower your costs.

The system is pretty simple if you take the time to understand them. Some complain that repairs are expensive but most owners report that the system is pretty bullet proof overall and have only had to replace the odd injector or intake boot. Relatively inexpensive.

Thanks for the input, I am seriously thinking about doing this, a transplant sounds good because all the parts should be there.
What is the best way to run a return furl line, (69) no fuel inj. evident on this chasis (standard) PO has installed a DP 1600 that I am cleaning up now.

It depends on if you want to do a proper job or just a job. I have a 412 that the PO ran a soft fuel return line back to the tank because the hard line had a blockage. You will need to run a hard return line either through the tunnel or under the underside. You will have to find a gas tank with a fuel return spigot or modify your existing one. In addition to this you are also going to have to change out your rear apron to a '75+ to fit the FI exhaust, then this also will present troubles having the rear fenders match up with the apron. You may have a little body work in your future if you take this project on.
