Remote gas tank and electric pump

[Brianpfreeman]

Have a 30 coupe I’m going to get running. Gas tank is rusty and leaks. Overall has good patina paint. I was thinking of buying a new universal tank and mounting it behind the seat. I would fab filling neck and have to open the rumble seat to fill the tank( which I’m completely fine with). People that have relocated their gas tanks for any reason, what tank did you use and what pump did you use? Will be running stock banger and 12v system.

One of our club members installed a '32 tank at the rear of his Tudor for that exact reason.

I installed a barrel type 12 gallon tank in the rumble seat area of my coupe. Drilled a hole in the floor and ran the gas line up the drivers side (away from exhaust) and then over the transmission and up the firewall. Uses a 2-3 lbs carter fuel pump mounted in the frame rail close to the tank. You cannot run a zenith with the fuel pump. I switched to a weber and it's been fine for 2,000 miles since June.

Thanks for the info. I have a zenith carb. Why won’t it run? Pump over power it?

I mounted a15 gallon rectangular tank behind the seat
Plumbed hardliners up to pump mounted on passenger side frame rail
Using Holley 1-4 psi pump into a 94 carburetor

The pump you are using is overwhelming the float and needle valve
The original carbs were designed for gravity feed
On racing karts with motorcycle carbs we used to make a bypass type fuel feed
It supplied fuel to carb but not pressurized the return line creates enough restriction that the carb will feed without flooding

Do you have any pics of your setup?

Tank is from Tanks inc

Nice looking set-up

Another advantage of a remote gas tank is that you can gut the original cowl tank and put an AC unit in it. Or radio, or etc.

I Have been running an updraft zenith with a 12v system and a pressure regulator on my car for over two years and no problems. It can be done.

As stated above, run a return line then use any electric pump you want, it won't develop pressure for the Zenith but will feed the carb just fine.

[Brianpfreeman]

Can you explain a little more? Are you hooking up the return Line to the pump so it’s very low pressure and blocking the feed line After the regulator? Sorry only built street rods with modern EFI stuff, so trying to make sure I learn/understand this right.

Good idea

Similar to efi put the return line as close to the carb as possible
This will make sure to push any air out of the system
It doesn’t require the pump close to carb
I would suggest the return line same size as the supply from pump

I have A/C with the original tank.

Don't like the idea of gas tank in the car, didn't the gov make ford remove the interior model A gas line, that's why the B has rear tank?

[johnneilson]

As I recall, Ford didn't do too well putting the gas tank under the car with the Pinto.

[Benson]

The Pinto gas tank problem was NOT the fact that it was under the car.

It was with HOW they did the installation.

From Wikibooks:

https://en.wikibooks.org/wiki/Profes...Daxle%20design.

Design Flaw
The Pinto controversy centered on a single design flaw which made this “carefree car” a potential deathtrap. Ford engineers chose to place the fuel tank at the back of the car, directly between the rear bumper and rear axle. This fuel tank placement was common for domestic and foreign cars at the time, and was considered a conservative choice compared to the untested above-axle design. However, the potential dangers of this placement were exacerbated by other decisions made in the design process. Due to Iacocca's cost constraints, the walls of the fuel tank were exceptionally thin. The fuel tank design also incorporated four poorly arranged bolts, which protruded from the rear differential directly adjacent to the tank. [2] Rear-end collision tests showed that, in collisions over 25 mph, the protruding bolts punctured the thin walls of the fuel tank, resulting in fuel leakage. Sparks into this leakage had a high chance of ignition, culminating in fatal consequences.

While this flaw was discovered during testing, the short time frame of the Pinto’s development meant that final tooling had already begun.[8] Ford did not deem the fuel leakage as a major design flaw, because they did not undertake any retooling efforts. Harley Copp, a lead Ford test engineer, was a whistle blower during the Pinto's testing phase. In the later trials, he claimed the Pinto was "grossly inadequate and the weakest I've seen in cars for the last 10 to 12 years". [10]


MORE:

Recall
Rather than wait for the public hearing, Ford agreed to do a voluntary recall on the Pinto on June 8, 1978[21]. In the end, Ford recalled over 1.5 million vehicles, which was the largest recall in automotive history at the time. Despite putting out a recall, Ford disagreed with the NHTSA's conclusion[20]. Instead, it maintained that the recall was simply to satisfy the public concerns resulting from the unjustified criticisms of the fuel system[22]. However, Ford did also mandate a number of modifications for each recalled vehicle, including inserting a protective shield between the fuel tank and the differential bolts, and a new fuel-tank that was more resistant to breaking during a rear-end collision[22].

Some suggest to use a 12 volt relay to run the Carter pump

[Pete]

I have done several gas tank moves on model A's.
I use a 16 gallon fuel cell and mount it with 2 complete encircling steel straps under the rear of the car behind the rear end. If you have a rear mount spare tire, the installation is almost invisible.
I use a Holley electric fuel pump with a rollover switch and an Aeromotive bypass type regulator.
The fuel cell has provision for a gauge if wanted.
