Alright, I have been researching and reading a NUMBER of threads regarding the FiTech EFI conversion.

I see that a few replace their gas tank. My question - is it a MUST to replace the gas tank? And - is it a MUST to replace fuel lines?

FiTech advertises the EFI units and combine with either the command center or external fuel pump. Can a conversion be completed with just these two purchases? (and some labor)

The external fuel pump includes fuel hose, so I assume it is required for use. The command center does not so I assume it uses the original fuel lines.

No, you don't have to replace your fuel tank if you use the Command Center. If you have a stock fuel line 5/16 ID then I would replace it with a 3/8" ID, but that is just my opinion. I just replaced my old stock line with a new 3/8" ID line as I'm doing EFI.

The Command Center uses the stock fuel line, and your stock fuel pump to get the gas into the Command Center, and in the Command Center is a high pressure fuel pump to get it to the EFI system.

So to answer your last question, Yes with two purchases you can have EFI. I would still replace the old stock line as it is probably rusty inside.

I just bought the FiTech EFI model #30004 Power adder. It is on back order until May 6, 2016.

I at least get the time to put in the new Tanks Inc. tank and run all the SS braided PTFE hose.

Has anyone with the FI Tech EFI had stalling issues on hard decal/braking, and if so were they able to fix it? I am having this issue with the MSD Atomic and wonder if going to Fi Tech would work better.

There are two pretty serious Autox guys that were sponsored cars I believe that run the FItech setup in SoCal without issues from what I know. Pretty sure they may be doing Optima USCA as well.

Is your EFI unit also controlling your timing? I have an MSD distributor and 6AL controlling my timing instead of the FiTech unit, no issues so far with stalling.

The car ran worse when the EFI was controlling timing so we went back to the MSD distributor and 6AL. I haven't read any posts where stalling is a problem with FiTech. MSDs forum is full of issues that don't ever seem to get resolved, including stalling.

I'm curious what is your fuel pressure doing when this happens? Is your tank baffled?

Using a modified MSD ready to run dis. with the 6AL and the Fitech timing control..
Runs just as good but maybe no better than the old way....ADJ the timing from inside the car is nice..
I have swapped back and forth at least 4 times with the timing control trying to fix different issues...timing control was not the problem..
Car has never stalled going down the road unless I screwed something up....AND I HAVE..

The fuel pressure is steady throughout at 47. The tank isn't baffled, has an in-tank Aeromotive Phantom 200 electric fuel pump. The stalling happens even with a full tank of gas.

Dear friends,
I'm thinking about to buy this EFI system for my '65 with 289. Will opt for the fuel sump thing too.
What about the timing option in the system.
At the moment I'm running the stock distributor with a pertronix and vacuum advance.
Can you give me some advices for new distributors and needed parts (brands and part#'s), that make the swap easy and almost a bolt on.
I live in Switzerland and do not have the option to buy these parts around the corner. so I have to have them ready to play.

Any suggestions are welcome.
I use my Mustang only occasional, but want to have the EFI thing. I don't need the latest state-of-the-art parts. So please give me some ideas for a nearly cheap buy (like Summit oder JEGS, or if needed MSD).

Many thanks in advance
Phil

Straight from FiTech that if your happy with your dist controlling timing there is no real advantage in having Fitech unit control timing. That being said if you needs are less than 400 HP I would buy the GoStreet unit and the Command center. This unit doesn't control timing but it's $795 and if you can catch the rebate for $75 That's $720. You just need the Command Center for $395.

Summit, Jegs or Pace

You can install the EFI system first and use your existing distributor and then upgrade to timing control later. Some people get into trouble when they do both at the same time and then can't figure out whether it is the EFI or timing causing the problem. I hope to install a similar system soon and get it running well before going to timing control.

Well I'm having issues now, I have the power adder version. My unit keeps shutting off while I'm driving. It just does a quick flicker, nothing else in the car is losing power. I've tried running the power wires for the unit straight to the battery. I've welded a ground to the rear trunk frame. My battery is new and fully charged and is mounted in the trunk. I'm not running any timing control, or fans (disconnected those to eliminate everything) I wanna pull my hair out lol..
