Anyone put a fuel cell in a 64-66 Cuda? Bad idea? Fumes?

Hello all,
I need a new fuel tank and am going efi. Thinking about putting a 15 gal fuel cell in the trunk of a 64 Cuda. Bad idea?
-I would build a firewall but still concerned I would be chasing fume issues.
-Want to cut a hole in the cell for a stock magnum efi pump (which includes regulator and plug and play with my stock efi)
-Other option is Tanks Inc efi tank, pump, regulator.

If you have had luck with a cell in the 1st gen Cuda or similar, please let me know!

There is only a small difference in vapor barriers between the fastback and any car with a trunk.

The "vapor barrier" is the trunk floor. THERE IS NO vapor barrier in any trunk car. It's a piece of cardboard, and the rear seat. Plus, the rear speaker holes / package tray is not sealed either LOL

LOL, when I saw my email alert that GRUMPY PETE responded to my question I braced myself for a "GRUMPY" response like "hey dumb *&^ just put the fuel cell in and figure it out!" But instead Grumpy and I will be on a mission to figure this out, LOL
 
I personally don't like the sound of it, but let's "go back............"

Mustangs and a few other cars.........in a Mustang, the tank top is the TRUNK FLOOR. For many many years, lots of 'murican pickup trucks had the tank in the cab behind the seat.

You will never make it at a dragstrip with a trunk fuel cell unless you provide a firewall between the tank and passenger compartment.

Thanks for the response, yeah history has provided many iterations of fuel storage location. A wall would be necessary. Mostly I am looking for a "success story with venting" on this particular vehicle.

You could buy a new oem style replacement tank and modify it for an EFI pump.

That's totally logical and I went that route theoretically, however, it would require a hole cut in the floor board to make room for the top of the pump, essentially putting me in the same boat as a trunk fuel cell. It's kind of either put the entire fuel storage under the car, or the entire fuel storage in the trunk. Regardless, I appreciate your input, this forum has really helped educate me!!!!

Oh yeah, I had 2 buddies go get a 396 C10 shortbed from North Dakota, drove it back to So. Cal with a leaking gas tank that was IN THE CAB! They said it wreaked of gas the whole trip back and had to drive with the windows down the whole way. They found out the tank had a split seam on the top so it never leaked fuel, just vapor. That is unbelievable design work.

Yeah, hard to believe some guys sat around and thought that was a great idea for location of fuel. Crazy.
 
woulds this work ?

Bad idea. Don't run a cell. There is absolutely no reason to.

You can hook the factory fill to the cell and vent the cell under the car. That would eliminate any smell but you'll still lose your trunk.

Here are 2 viable options and you can still keep your trunk.

1. Hot rod city garage makes aluminum fuel cells that bolt in the factory location. They can be setup for EFI, etc.

2. Aeromotive makes stealth tanks and EFI pumps that work in them. These require a bit more fabrication work to install but have some other advantages.

You could step down the mounting surface of the pump, or create a hump in the floor with an access door.

Or...contact those guys roccodart440 mentioned and see if they offer something that fits your car.

Here I spent 2 minutes Googling and found your answer:

Fuel Injection Gas Tanks

Yeah, in my original post I mentioned the Tanks Inc EFI Tank as a route I may go.

Get a stock tank and modify a top corner.

That's actually a really great idea and a guy on this forum had success with this in a dart. Unfortunately, with the older cuda the best corner for the pump places the hump past the trunk and forward a bit into the rear deck. A huge cost savings but didn't like the idea of the top of the fuel pump being in the travel area (even with a small fabricated box to cover it)

no diff from a cell in any trunk, "vent to the outside!" I would seal the divider anyway. Only sealed battery beside it if it`s in the trunk too, or you should use a sealed battery box. I prefer a sealed battery back there anyway .
 
The issue with a cell in the trunk is that you lose the trunk and when you fill it (if you don't hook up to the factory fill) you get fumes in the trunk when fueling the car which stink and can also cause a combustable vapor hazard.

Thanks for the input, an important point regarding hooking up the factory fill. I'm already now leaning towards the Tanks Inc EFI Tank.

I really didn't think about doing it that way with my last car and deleted the car door. Looked great, function not as great.

I also replaced the trunk floor with a shaped tub so I could sink the cell down and still have a trunk. This worked ok but was unneeded and added a lot of work sand money to the car that didn't need to be done.
