Going to FI

Post by whc03grady » Tue Feb 27, 2007 1:46 pm

I was wondering just how hard it would be to replace my current aspiration with fuel injection, assuming I obtained a working set up. Questions that come to mind are:
Would I need new heads?
Would I need a different gas tank?
What about the distributor (currently a 009 :pukeleft: )?
I'm sure there are many, many other things to think about also. I was planning on rebuilding the stock carbs that came on the bus and putting them on, but then I got to thinking that maybe for a little more work I could have the best of the best, that is, fuel injection.

In short, has anyone converted a non-fuelie to a fuelie? How much stock in Excedrin did you have to buy?
Ludwig--1974 Westfalia, 2.0L (GD035193), Solex 34PDSIT-2/3 carburetors.
Gertie--1971 Squareback, 1600cc with Bosch D-Jetronic fuel injection from a '72 (E brain).

I have not done it, but as I recall, some things to think about are:

1. You'll need a fuel tank with both an outlet and a return line.
2. You don't need new heads, the injectors mount to the manifolds.
3. Wiring from the ignition switch to the double relay, then double relay to everything else it feeds.
4. Support bracket for the air cleaner and AFM unit.
5. Somewhere to mount the computer.

Another option is to convert to the Bosch CIS injection that was used on the water-cooled cars. See this thread:

My understanding is that well-tuned dual-carbs are nearly as good as FI.

Plus you are going to have to tap the head for the engine temp sensor.

Randy,

What else might you be able to tell us about this "Temp Sensor" thingy?

I am a champion of the dual carbs, driveability has been as good as FI for over a quarter century (minus a little too much choke fast idle in cool misty conditions). They are simple, robust, and demand a functional dual vacuum advance distributor.

you tap the engine tin screwhole right by the #3 manifold stud for it. Can't remember the exact size...10mmx1.00 pitch I think. pretty simple to do.
