Re: [Amc-list] tbi adapter for 196

I have my return line in the filler neck!
Easy to do as you say.
I bent steel line in a 90* bend, drilled a hole in the neck, then I used the drill bit to elongate the hole so I could pull the line back and keep the inside portion as close to the inside of the filler tube as possible.
  I carefully tack welded the line into the neck, then soldered it, last I cleaned it all up, very, very carefully and JB welded over the solder! Overkill, yes, but hey I don't wnat any leaks!  
  It's kind of cool, with the car running I can hear and see the return fuel running back into the tank on the American!

  For grounds on mine, when I was doing the install I had the underhood Wrangler harness so I took the 10 gauge wires in that harness and used them to connect all the existing ground points on the American body.  I ran it from the Firewall connection to the block by the old coil mount and from that point it crosses over to the fender mounted starter solenoid. I installed the heavier grounds too.  I also installed relays in the headlights to take the load off the old headlight switch.

   Once I had everything up it all works good. I have never had any issues with the system at all. Not TBI, but the same basic principles apply.

Having done only one system, my '63 Classic wagon, the hard parts were:

tank return line plumbing (BUT SEE BELOW)
fuel pump in frame rail
wiring harness (note)
throttle linkage
mounting computer

tank: I had the tank out, drilled a hole, installed a real return line.
Waste of time and prone to creating leaks. What I would do next time is, add
the return line to the tank filler neck, at the tank, with 12" of steel line
to run the fuel inside, rather than just drip into the neck. I can see no
downside to this, and you can probably do it on-car.

wiring harness: mine was easy, as it came with the Howell kit I bought from
Russell. You'd have to lop out one from the donor car. The big connectors to
the computer would be a pain and/or expensive to do yourself. But if you had
to add, or extend, etc, one or more of: fuel pump relay, fuse, MAP sensor,
IAC, or injectors, that's just two wires each thing. (I would NOT! use
crimps for those, but strip, twist, SOLDER, and heatshrink. Too critical.)
The harness ground is CRITICAL, and goes to the intake manifold, NOT the
chassis. The manifold is where the injectors are....

throttle linkage: likely full custom. But it's just metal.

Then there's the tuning part. You need a laptop, some hardware like Moates'
AutoPROM ($300). The actual tuning process is easy, if you are comfortable
with a spreadsheet. It seems likely that I'll do the 195.6 at some point.
