Had anyone had good luck with either the Tanks Inc. EFI fuel tank or the Spectra EFI fuel tank such as here: Spectra Cuda EFI Fuel Tank Just wondering if these work well when there's 1/4 tank of fuel -- I mean, does it starve the fuel pump at an unacceptable level, or does each one work well?

As much as that at face value seems to be a plus, adding a considerable bit more plumbing, tank, wiring, etc, that still includes high pressure, in a area rather venerable in our older cars in even a minor shunt, seems to possibly offset that upside. So you're saying it makes more sense to have the entire system from the rear of the car under high pressure than just the front-mounted sump !?!?!?! Less plumbing than a full return system. Wiring - to the front or to the rear - what's the difference? The sump system is about as compact as any "in tank" system. The installation of a sump versus any other efi pump system is just so much simpler and faster. The sump just makes way more sense. You just need to find one that supports your HP. The Edelbrock one is pretty slick but makes no mention of what kind of HP is can support. The front mounted sump solves some problems, I personally don't see a great problem with high pressure fuel lines running, correctly placed, front to back. Nearly every modern car has this set-up. What I don't like is, with our older cars, with little designed in crush zones, the mounting of the sump system, that also has HIGH pressure, and more of concern to me, a quart plus of fuel, located basically where ever space allows, with little concern to accident impact intrusion, etc. The difference being, all this electrical hardware and fuel quantity, which does not exist in a rear fed High pressure system is now in the engine compartment, probably in front of the engine, with a lot of hot engine parts nearby. It is not a very forgiving location, and still being fed by a rear mounted low pressure pump rated likely at a slightly higher gpm flow rate then the sump pump. It would be the location and mounting lack of concern that gets my attention. It is a solution that I would consider, and aim one of the in car extinguisher fire nozzles at.

No one has a Tanks EFI tank in a Cuda or Challenger?
If anyone has, I am curious if there are fuel starvation issues at a quarter of a tank of fuel.
Thanks,
Mark Not yet. Have some more plumbing items to get but I hope to be installing in three weeks or so. I am not sure why there would be fuel starvation. The sock for the fuel pump is nearly flush with the bottom of the tank baffle. I have had the tank dry fitted with the sender and the pump. Will be doing clearance tests with the sender boom and float as they are close to the pump. will have those done this week. Craig

Any more info on this? I saw the Spectra tank being offered on EBay by tomsclassics advertising 55-85 psi but no gph rating or description of the pump used. I guess the easy answer is to contact and ask but I'd rather hear it from a member with first hand knowledge...I know there are Walbro knockoffs offered on many Chinese sites and I'd guess that's probably what's being used. I ordered a Spectra Performance CR9CFI Fuel tank ('69 Coronet) with internal pump from Amazon ($366.02) to try out. It looks pretty nice. Made In Canada. The Fuel Pump that it comes with is a Walbro (USA) GSS342, 255 lph pump which should be good for 500+ HP? There is a tub type baffle/sump in the tank that the pump sits in.

I was looking at a Tanks Inc one, but they are not out yet. I like the separate sender unit from the pump. On the Spectra tank, the pump and sender are combined and it was a pain to remove it from the tank. Only reason I removed it was to see what pump was used and how it was baffled. I forgot to take pictures, but it looked decent, so I will just install it and try it out. I'll post updates after installing the tank.
One thing with the spectra setup, the pressure and return lines are 3/8" supply, 5/15" return, and they are the regular style where you push a fuel hose over the connector and tighten it with a hose clamp. I guess it will be OK with the higher fuel pressures? I'll find out. I did buy hose to -6 AN adaptors so I will just use a short length of EFI barricade (Gates) fuel line from the tank to the adaptor, than connect my existing -6 AN fuel lines.

More good info... thanks. I too was looking at the Tanks, Inc. model but the e body version is around $200 more than the Spectra tank. From the info you've provided it seems the Spectra is tough to beat. Thanks again for sharing your experience and knowledge... Depends on the vehicle. For E body, the Tanks, Inc is about $40 more. I went that route as I did not know what pump Spectra was using and there were no tanks in inventory. Now they are in stock and I know they are using Warbro pump, I would just as easily bought the Spectra. Craig

What sort of HP will the pump in the Spectra support? The Tanks unit can be purchased with different pumps to support different HP levels. At stock voltages, I think it can do 550 HP from what I have read. Some people use a voltage booster to get more? I removed the sender/pump unit to try and swap in the 450 LPH welbro pump, but the 450 pump is larger in diameter at the bottom and does not fit the bracket for the 255 lph pump, so I decided to just use the 255 lph pump and see how it works. Hopefully I can get the tank installed this weekend and see how it works.

I have been watching this thread for another reason. I am building a 64 Savoy wagon thats getting a 5.7 Hemi and Nag-1 trans. The gas tank rests vertcally in the left quarter panel. I don't see any way to add an in-tank pump, so I have to have an external high pressure pump. Relocating the gas tank is out of the question.
