I went with a TanksInc tank for my 68 Charger and I'm not very happy with it. I used their in-tank pump setup and I will not go this route again. I had clearance problems and leak problems. In my other car (69 GTX) I used a stock tank (Spectra IIRC) and an Aeromotive Stealth 340 pump. In this case a hole was cut in the top of the tank, pump installed and the tank sealed back up. Two AN fittings are welded to the top of the fuel pump cover. Much cleaner and less prone to leak. The TankInc uses NPT fittings. Same issue and worse, you had to keep dropping the tank to work on it. After three drops, your out. Spectra in, no leaks, not errors. Craig

I thought I saw somewhere that Spectra was making EFI tanks for older models ... If so, whose selling them? I got a great deal on a Spectra EFI tank for my 71 Challenger through Rockauto. Discount code and everything. It is basically a stock tank with some EFI stuff thrown in it...

So does it have a recess for the pump ?? It is built into the side of the tank. I'll pull it out and take some pics tomorrow.

The B-Body spectra tank has a tub like area the pump sits into. It seems to work good, but I never ran it with real low fuel level? Power the pump with a fuse to make sure it works before installing the tank. Originally, mine (early production) had the power wire touching the metal frame where the wires go through the sending unit plate and shouting out. Fix was easy, just rotate the wire connector, but finding out after installing the tank and filling with fuel. Link to old thred https://board.moparts.org/ubbthreads/ubbt...tml#Post1934775

The pump location on the Spectra tank presents limitations - if you need a higher output pump for a higher HP application, what do you use ??
It was mentioned the Tanks Inc. had issues with leaks. What kind of leaks are we talking about - fittings, gaskets, what ??
It looks like the Tanks Inc. pump mount is specific to their pumps and any others require major surgery to the mounting flange BUT they do have a good selection of pumps. Are there any issues with their pumps ? The first leak I had was with the venting. I filled the tank and the expanding fuel with heat sprayed fuel all over the spot where I parked it. Luckily, that was outside. Remounted the vent even higher and remounted the tank. My error. Second leak, NPT threads on pressure side would only show up with the pump running. Not a big leak but still was flooding the top recess of the tank where everything mounted. Drop the tank, put Indian Head on the threads on it and the return as well. Remounted. Third leak was on the AN to NPT fitting on the pressure side. Very slow leak but filled the garage with gasoline fumes and complaints from wife so dropped it the third time. Bought the Spectra from Rock Auto. Got very good at draining the tank. Pulled my Ram to the rear of the car and used a Holley electric fuel pump to transfer the gas to truck. Lower it with a piece of plywood between a floor jack and the tank. The advantages of the Spectra tank: 1 It's outlet is exactly where the OEM was. A short piece of injector line with injector clamps hooked it right in. NO LEAKS 2 The ground strap to the tank can be also reused although it is not needed for the pump and fuel sender returns. I like having the tank at electrical ground for safety. 3 Last but definitely not least, the fuel sender for the gas gauge is the proper resistance for the Mopar system. When the tank is full, so is the gauge. Likewise for empty. The Tanks Inc sender is built to Ford specifications so it will not go to full with a full tank, just to 3/4. Never got the opportunity to see what empty or close empty looked like. I did use a MeterMatch from Technoversions to correct the gauge for full but that is another cost to add to the system. 4 The Spectra uses OEM vapor seperator and vent system making that part work much easier than the Tanks system. One other thing to watch with the Tanks Inc is the feed wire for the sender. The attachment nut can easily be stripped with just a nut driver tightening it down. I bought the Tanks because the Spectra while announced was not readily available. There also was not a lot of information about the Spectra. When Rock stared stocking them, the price alone made it very competitive. BTW, both tanks hold the exact same amount of gasoline. Hope this helps. Craig

Awesome, how'd you get that inside pic? Scope through vents?
Forget it, filler tune opening.......duh

this is the answer Fitech came with when I asked what the minimal L/ph need to be for my Fitech Efi: Hi, How much does the EFI, part number 30002 need? With the Fuel Command Center the pump delivers 340 l/ph. With the external pump, part number 40005, the pump delivers 225 l/ph. What is the minimal flow rate the throttle body (30002) needs? I'm looking for an in tank pump and would like to know which possibilities there are. Thanks in advance! Robin Answer: Hi a 255 LPH pump will support you up to 600 hp, and works well with the go EFI 4. But either pump will work. Anything else let me know --- Thanks Kirk Spiger Tech Support FiTech Fuel Injection 12370 Doherty St. Suite A Riverside, CA 92503 Phone –951-643-3848 www.fitechefi.comNot real satisfying...

The reply seems pretty clear to me. The command centre will support up to 800 HP (340 lph) but your 30002 is only rated at 600 HP as is the 40005.
How can it be any clearer - and I got all this from their website !!
So if you're looking for an alternative to an FiTech pump, look for one that matches or is greater than the 40005 output. I thought in all accuracy when using the command center, it requires a low pressure pump to feed the command center, and that, and the line size, distance, routing could also factor into the HP level supported? And Command center effectively does not have to counteract any acceleration negative effects if mounted in front of the engine?

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

I pulled the Spectra CR9CFI pump out and it is a Walbro (USA) Part number GSS342, 255 lph pump. Reference: http://walbrofuelpumps.com/255lph-walbro-gss342-intank-fuel-pump.htmlI bought a Walbro TIA485-2 pump, 450 LPH that will run E-85 and I was going to run it in place of the GSS342 pump, but I would have had to modify the bracket holding the pump, and just decided to use the GSS342 pump for the time being as I have not gotten the new ECU and flex-fuel sensor wired in. The CR9CFI with the GSS342 seemed to perform just fine with the old Edelbrock XT EFI system, but I'm probably under 500 HP at this altitude.

One reason I did not get the Spectra originally was the lack of information from Spectra on what they were using. 255 l/h is fine for my application. Craig

May go this way...
