This, I also have a C6

 

I used the LOKAR kickdown kit and it works perfect!

 

Yes, as is the case with a lot of carbs also. FiTech told me that they use quick fuel throttle shafts. I used the Autoloc cable, which is a Lokar knockoff for like 1/3 the price. My only gripe is the trans bracket was a PITA; the bolt was a bit long and the head too large.

It also doesn't come with the bracket to attach to the carb/tb

 

fuel tank wise ,is it better to have in tank fuel pump vrs mechanical for the efi conversion?

 

The pump doesn't necessarily need to be in the tank... But an electric pump of some variety is going to be needed as the mechanical pump doesn't make the pressure needed. Usually the electric pump will be mounted on the frame as close to the fuel tank as possible.

I keep going back n forth on carb vs EFI. I think the reliability of EFI even extremes (weather, altitude, angles, etc...) is winning me over. Probably worth a few hundred extra for this.

 

That's where Im at,,just recently someone did a write up of a superduty tank,that it fits highboy frame,,,tank has fuel pump in tank,,just putting thoughts togeather

 

If you already have that then heck yeah your halfway there. Most of these EFI systems require a return line. Be sure to account for that as well but that may also be taken care of.

 

Ah, tell me about it!! Living in Alaska here and also hate having to babysit it for 5-10 minutes in the morning! Currently have a sticky throttle situation to iron out which makes it even more annoying!

 

I have the 30003 setup on my truck...few bugs with my truck but I have it up and running good now

 

So why is the fuel commander a needed item? For simplicity, lets say you only have one fuel tank. Can't a person just use a regular high-pressure electric pump and add a return line, eliminating the factory mechanical? I don't really want to add a bunch more "stuff" under the hood, and I have a basically stock 400, so I'm not figuring on big power. Is the factory fuel line just flat too small out of the tank?

Another possible option, I know guys have hung later-model fuel tanks under these - could a person use later-model tanks with factory, say, '94 era in-tank pumps?
