https://www.flickr.com/photos/13718356@ ... 4648006172 the throttle cable and 904 kick down cable are installed. for the throttle, the OE Vortec TB has a cable bracket that caught my eye, in the OE application the bracket holds the throttle cable and a cruse control cable. I shortened the OE Vortec throttle cable considerably, had to add a 4 inch extension to the 68 Barracuda gas pedal arm to match the pedal travel to the TB blade opening ratio,, that took one port on the OE bracket Installed a Lokar kick down cable into the second bracket port,, added a short actuator arm to the TB cable spool to make the attachment. the injectors, rail, regulator are installed, removed the stock fuel tank and began preping the Tanks Inc fuel tank. On the list for this Saturday is installing the new tank, running lines from the tank to rail. concerning Quote: Slightly shorter fuel rail
I am installing this FI system: Clifford intake- Vortec TB- Rail, on the 68 Barracuda, however the final destination for this assembly will be on the 83 D150,, The D150 has a AC compressor that resides right in front of the TB. Makes that area around the thermo housing somewhat crowded. I am preserving the rail length to keep options open when it gets re located.

installed the fuel tank today,, went with the Tanks Inc unit,, long way from the pull a part and salvage yard parts that I normally work with,,, * pump is a made in USA Walbro unit * level sendor checked to within factory ohm's for full and empty * finish and fit of the tank and components were without issue. * buy through Summit, get free shipping pricy part, but I don't see myself being able to modify a stock tank to this level of FI readiness without a lot of effort: * internal full length E to W baffel to minimize front to rear slosh * about a 6 x 6 x 4 internal cup for the in tank pump to set in,, appears that it would be very effective in keeping fuel up and around the pump. https://www.flickr.com/photos/13718356@ ... 4755158732 included are some side by side photos of the OE and Tanks Inc tank,, the new tank went in with out a hitch. |

Quote: have it running
still need to:* wire in the fp, sensors - ecu,, this looks to be fairly straight forward * develop & input the fuel maps, figure out the Tuner Studio,,, as I have no real experience doing this,,difficult to determine if this step is a day, a weekend or a week... I am planning to do only ecu fuel control initially, get that running, then add ignition control. it will be running in March,, likely late March. |

the Fuel Injected Barracuda started today.. https://www.youtube.com/watch?v=OjyJG9Bqn04 the gauge that shows red on the lap top is the AF gauge, that matches the reading on the AEM AF gauge that I already had installed. Apparently the initial setting in the MS unit is plenty rich. plenty of blow by at the oil fill, as I had not yet hooked up the PCV hose, and that is the OE 68 motor, OE pistons, rings, bearings.. next step is figuring out how read the data logs and actually tune this thing.. |

I did not think a gas motor would start at 20:1, let alone idle at 2000 RPM, so I guessed rich,, but do believe your interpretation of the gauge is correct.I have some free time tomorrow AM,, will check it out closer, I had a just a few minutes of free time today, went to the garage, powered up the MS, turned the key and it started,,,, Right Now, Me Happy! |

You could be reading 20:1 because it is super rich and misfiring too. AFR gauges can lie to you this way. Been there... You can search around using reqfuel adjustments first to get the idle to be smooth and then go from there. I have seen several instances where relying on the AFR gauge can get you WAY off from the right mixture, due to misfiring. Lou |
