M1A1 Stainless Early Bronco 23-Gallon EFI Fuel Tank

WILD HORSES has officially moved the Early Bronco fuel tank into the modern era with the M1A1 23-gallon Stainless Steel Fuel Tank.

Built with 14-gauge stainless steel, this tank leaves rust in the dust and guarantees durability that lasts a lifetime. Our welders are true artists, delivering unmatched craftsmanship on these fully TIG-welded tanks. No more wavy, distorted surfaces—just top-tier quality. Plus, with a convenient side drain plug, maintenance just got easier.

Heavy-Duty Skid Plate: The included 3/16" thick armor plate protects your tank from rocks and trail obstacles.
High Capacity 23-Gallon Fuel Tank: Perfect for long trips without needing frequent stops, this high capacity gas tank adds 10 gallons of extra fuel capacity over the stock tank.
EFI-Ready with Included Fuel Pump Module: A quality, high-pressure fuel pump is included with your new fuel tank. The M1A1 fuel pick up module can be easily swapped out later if your needs change. The module provides ports for fuel supply, fuel return and venting.

This gas tank is secured under your Bronco with custom-made heavy-duty candy cane bolts, and the 3/16" thick armor skid plate offers unbeatable side and bottom protection. It’s designed to take a beating while keeping your tank safe from trail hazards. The M1A1’s fuel pick-up module is flexible enough to work with or without an in-tank fuel pump, allowing for future upgrades without hassle. The module provides ports for fuel supply, fuel return, and venting.

The M1A1 also includes a custom reed switch style sending unit, designed specifically for this tank to ensure accurate fuel readings. And with its optimized ground clearance, you’ll have better off-road performance and a sleek, stealthy look from behind.

Tough, modern, and built to last—the M1A1 is the ultimate fuel tank upgrade for your Early Bronco.

Asked by Brent, October 15, 2023

Q: In reading the answer to a previous question, it sounds like the included fuel pump runs at 90 psi. But the Edelbrock Pro-Flo 4 system requires 43-45 or 58-60 psi. Is the included fuel pump pressure adjustable, or, is there an option to order the M1A1 tank with a fuel pump that is compatible with the PF4 system to avoid using a fuel pressure regulator?

⮞ 1 Answer

Answered by ☆ sales - October 16, 2023

A: You will need to use an external pressure regulator to dial back the pressure. Something like #6662 or 6669. We do not offer a lower pressure pump.

Asked by SW, September 12, 2023

Q: Working on a build that will have a 5.5 in. lift. Noted in the specs that this works with up to 3 in. lift. Will any special modifications be needed to use this tank (including skid plate) with 5.5 in. lift?

⮞ 1 Answer

Answered by ☆ sales - September 15, 2023

A: When we mention the 3, that would be a body lift, stock mounts up to 3 body lift. It will work with anything from stock to 5.5 of suspension lift. We expect no issue.

Q: I have a MagnaFlow dual exhaust system from CJ Pony Parts with the X pipe and 2 1/2 mandrel bent pipe exiting behind the rear wheels. Is there any known interference issues with this tank?

⮞ 1 Answer

Answered by ☆ sales - April 4, 2023

A: We have heard of some interference with exhaust coming straight out the back. We are not aware of any issue with a side exit, but either way, it really just depends on the exhaust install and routing.

Asked by Jon Mathew Armstrong, January 26, 2021

Q: can this tank be used with a carburetor with the in tank fuel pump? I have intentions of doing efi, just not immediately. Or would i be better with the non in tank pump version until i do efi?

⮞ 1 Answer

Answered by ☆ sales - January 29, 2021

A: Not normally, but, you may be able to add a pressure reducing valve and return line setup and accomplish that. The EFI pump is capable of 90 - 110 psi. Most 4 barrel carbs only require 4-7 psi. You will be moving way more fuel than you will need, and have to find a Pressure reducing valve to do it. Or find a low pressure equivalent. Depending on your EFI choice, you may need a PRV eventually anyway. Or, get the tank for carb, and get the pump kit when you need it, #9667.

Asked by Larry, December 18, 2020

Q: Should the skid plate be painted? Also, what are the two tabs with holes that are in the front of the plate for?

⮞ 1 Answer

Answered by ☆ sales - December 22, 2020

A: The skid plate should be painted or coated. It is regular mild steel, and not stainless and will rust. The holes are not for any specific purpose, and are just part of the current design.

Asked by Jeffrey Wilkins, November 15, 2020

Q: I am doing a frame off of a 75 Bronco. I will be running a Blueprint 306 w/Sniper. Do I need to run a tank vent on this application. If so how?

⮞ 1 Answer

Answered by ☆ sales - November 16, 2020

A: You will at the very least want a vented gas cap. If you can tie into your original, if still in place, vent system, that would be good. Otherwise, some will run a vent hose with a check valve up into the tail-light housing. To allow air in, but not fumes or fuel out.

Just installed my new M1A1 yesterday, everything went well except the tank install itself. The j bolts were bottoming out on the frame making the bolt angle too steep. Took about 1/3 inch off the j bolts and the install went great. Love not having to worry about rust! Thanks Wild Horses for the fast shipping and the great product!

Very tight fit- but looks/works great. Very well made, ran a 400 mile cruise right after installing and had no issues at all.

I've gone through two of the other brand 23 gallon tanks and the stainless version is by far the best. Quality is superb. I bought the tank, skid and EFI version. Skid plate is far beefier than I excepted. One install recommendation, test run the fuel pump bracket all assembled before putting it in tank. Use a 5 gallon bucket and 1 gallon of gas, smaller jumper cables from battery charger to pump, fire ext.. I use a supply line output with valve so I could test the pressure and glad I did, leaks at fittings and hose clamps. Hose clamps just needed to be tighter, brass fitting leak at brass supply fitting needed pipe thread compound with TFE found at ACE hardware. The hi tack would not seal, TFE did, works great. By doing this test you also know its primed, it works, no leaks, ready to go. Thank you WH for this product.
