FiTech Fuel injection

[noreastfish]

I bought a FiTech fuel injection system for my 1970 Challenger with a 383 engine. I bought the command center so I don't have to run a return line to the fuel tank. I do however have to run a vent line to the tank. My question is what would be the easiest way to do that. Should I try a T into the vent line from the filler neck to the gas tank. I don't want to drill into the gas tank. The car is all stock and I'd like to keep it that way. Any help or ideas would be appreciated.

Just get a new tank for FI:

If you can return the command center I would send it back...    To many problems & no enough benefits...    But the Tanks Inc EFI tank & run a return line...

I have to concur with 1 Wild RT, a new Tanks Inc tank and pump will serve you way better with less problems.

As to you vent, Pick up a new filler tube and put a vent in the top of it near the inside quarter panel, then run a line through the trunk floor. This is how I did my Challenger. I believe the 73-73 (maybe even the 72) had a vented filler tube, but I could be wrong on that.

If you search through the FiTech owners facebook group, it won't take long to see how problematic the FCC is.

My Father in Law bought one, but I convinced him to return it and run an in-tank. No problems thus far.

If you have allot of emission control hard lines leading from your OEM gas tank that you are not using, you can one of those as your return, as long as the ID of the hard line is large enough

There is another option:  I forgot what company it is (Maybe Moroso), but it is replacement gas filler hose that goes from the gas tank to where it connects to the filler neck.  Halfway up the hose is a metal collar with a hardline fitting that your return line attaches to.  The fuel then runs down the inside of the filler hose and into your tank:  I believe the FI Tech instructions even tell you where to get it

A couple of points;

1. I talked to Fitech at Barrett Jackson last month and they have brand new FCC that they swear is completely redesigned and overcomes all of the issues attributed to the original version. They showed it to me and explained why it was/is better. They were pretty convincing and I have to say that I would consider using one. The new one can be mounted anywhere and in any orientation.

2. You can puck up a new sending unit as there are those that have a second inlet. I know this because I just got one for my Cuda because my old one died and I ordered a SS version off eBay and it came with one. The second inlet could be used for a return line easily enough.

I went with the Command Center 2 to avoid the same things others have concerns about.  There are lots of opinions around, and even some of the suppliers are selling the newer Command Center 2 matched to other brands of efi.  First - it works fine.  My 1973 had a factory vapor return line, I and I hooked it up with the assumption that the fuel return would pass through the vapor separator that feeds the four lines going into the tank.  When I first started running the setup, it stalled, put me on the roadside.  The CC2 got very hot and shut itself off.  Roadside diagnosis, I found the return line was pressurizing.  It cooled after a bit and ran and got me home.  I took the return line and bypassed the vapor separator by the tank, to dump return to one of the tank feeds. Dead-headed the other tank lines. Also drilled a 1/8 hole in the bottom side of the tank cap to vent the tank for sure. Problem solved.  The CC2 runs cool, using excess fuel to cool the enclosed pump.  With everything else heat soaked under the hood at 160-190, the CC2 body shows 115-120.  Feeding fine.  I don't like the bulk, but I do like the consolidated system which is slaved to the ECU with variable pump rate control.

Thanks great information. I like the concept of the CC but the size is a bit of an issue. That said, the Fitech guys told me that it could be mounted in any configuration and if that is true it might be a little better. I would probably try hiding it perhaps the front valance, but then you have the issue of it being in a location that will be damaged in a front end collision, but I guess it isn't worse than the gassers..

I got one and chose a different electronic fuel pump
very satisfied----
