sorry for all the questions, So it will pull fuel from the tank? And feed the EFI? Is the pump submerged in fuel to keep it cool? Very curious about this. Never seen or heard of it. thanks
well I googled it and looked at your pics/post again. So you have the mechanical fuel pump feed this thing and then it feeds the EFI. Interesting
 
It is fed by the stock engine mounted low pressure pump. The unit holds about a gallon of fuel in which the high pressure pump is submerged.

I have a Holley red pump on the rear that feeds my command center.
 
The mechanical fuel pump feeds the fuel command center, the FCC has an efi pump in it which feeds the efi throttle body unit. The only line running back to the tank is a vent, but it doesn't constantly run fuel back to the tank, just for over pressurization I believe. When I run that line back to the tank, it's going into the filler neck which FITech recommends.

what size fuel line is that vent? Can you just use a duplicate fuel line like the feed for most of it?
 
1/4". I'm sure you could use another hard fuel line. I'm just going with 1/4" fuel inj. hose and I'll use some adel clamps to secure it.

okay. Since it's a vent I guess tracks wouldn't boot you for it. They typically limit how much hose you can have. I am seriously considering this EFI since my Holley died and I am fed up with it at the moment. If I buy a new one, thats ~$600 and if I send it out to a specialist for a rebuild, that's also about the same cost. So for about $1500 for thecomand center and the throttle body I could have EFI. Looking at the web site looks like it's upgradable for ignition control (I'm running a recurved Duraspark now).
 
If I could go back in time I would have done the fitech on mine instead of the full 5.0 conversion. Seems like a pretty good set up.

For me I'm not running my timing through my FITech. I've read too many threads on how hard it was to get it to run properly. But I'm sure since it's a feature it can be done.

Pat did you do the wiring on yours? I almost forgot you had the stock type EFI

I did read in the FAQ section that they recommend setting it up first without it.
 
Craig, I decided against the Command Center in my set-up and went ahead and installed a new baffled tank with an in-tank pump. Not much more money and since you have to run a line back to the tank anyway why not make it a true return system was my reasoning. After all the effort to clean up the engine bay I didn't want a big canister and extra lines cluttering things up. I wonder where you would even stick the thing!
 
you have a good point! Did you "buy" the tank or make one? I have a 70 tank in mine now so I can go an extra 100 feet or so...

I put in a 22 gallon not that I will run around with that much gas but for special occasions (HPT) it will be handy. The tank needs to be made for an in-tank pump featuring baffles to make sure the pump pick-up stays submerged. I bought mine. Decided to go stock in appearance so went with a Tanks Inc unit. Glenns makes some nice pieces too but his is more obviously modified.
 
I have an Aeromotive tank (Tanks inc tank with fancy pump) on teh fastback and will be going with another Fitech prolly.

The coupe has a 22 gallons tank with a Holley inline feeding the FCC up front. My vent line is just routed to the radiator support, it should go back to the tank tho. My fitech doesn't have timing control, I opted for the 8 injector meanstreet version.
 
Detailed the majority of the undercarriage on my 68 coupe for our upcoming National show. Will do the front area on Tuesday.

Spectra makes a tank with a return and outlet in the stock location on the sending unit for the tank. It has an in tank efi pump as well and it's relatively cheap. Just have to run the electrical and the lines, which you could use stock fuel lines for.

I bought a wiring harness from RJM, but they are no longer in business I guess. It was plug and play. Took me maybe an hour to wire everything.

I had the original harness but the engine was speed density so I decided to upgrade to mass air. It was way easier to buy a whole new setup.

I would want to go stock appearance as my car looks like a 100 point original restoration...
but seriously thanks guys for all the info. Any of you actually have it on a running car yet? I have a pretty radical cam (108 LSA with lots of overlap) but again I saw in their FAQ that 8+ manifold vacuum will work. I get about that...
