I couldn't see LRA posting on this forum yet, if they did, my apologies and please delete the thread.


Hey guys,
We are excited to announce that the GX 550 aux tank is in development. We need feedback with regards to which tank will come first. A saddle aux tank or a rear aux tank.
The saddle tank will require an exhaust modification which will be Included and will allow for you to retain your spare tire. This tank will be +-16gal
The begins axle tank will require the spare tire to be removed or relocated to a bumper but won’t require an exhaust modification. This tank will be +-24 gallons.
Please use the link below and let us know.
Thanks,
Aidan
Long Range America

 
So how does this work?

You need to flip a switch to transfer gas from saddle tank to primary tank?

Or would they be integral?
 
for anyone in the know, typically, how would you fill up this auxillary tank?

edit - Looked at the Jeep saddle version and it looks like both tanks get filled up from the stock fuel neck

Saddle tank sounds great!
 
Has anyone who knows more about this than me investigated as to whether there is any room to just replace the stock tank with a bigger one to avoid the annoyance of 2 tanks?

Even a 20% increase would be huge.
 
The 16 gallon tank will add about100 lbs of fuel and the 24 gallon tank will add about 145 lbs of fuel weight.
This is negligible.
What is the weight of the tank and pipe installation for each size?
What is the price and how will the installation happen in different locations in the US?
Thanks
 
I had the 24 gal spare tire location aux tank on my 4Runner. It’s not the 2 hole filler neck. It fills the main tank first than overflows the aux tank. It’s awesome and easy to use. However it’s not carb legal and you will not pass smog legally in CA.

That's what I saw on the website. Bummer. I noticed that they have no installation affiliates in CA

Hi Adrian,
The begins axle tank that requires the spare tire to be removed or relocated to a bumper but won’t require an exhaust modification. This tank will be +-24 gallons is the best option to go for first, because it creates the best result for achieving maximum range, the main aim of the exercise. The obvious other issue is a rear wheel carrier with an immediate work around solution of the spare on the roof rack cage.
Many thanks for your efforts, you will please a lot of GX550 owners. Does the Various GX550 models create an issue, i.e. the Overtrail having additional EKDSS and rear lockers (I am guessing here)

I actually just cross posted from the Facebook group I am part of. I actually messaged Aidan to for join here as us here as there is some traction.

What Chat GPT says about CARB ('California Air Resources Board' for those who live outside):

In California, fuel tanks, including reserve fuel tanks, must comply with the state’s strict environmental standards set by the California Air Resources Board (CARB). Generally, CARB regulations apply to vehicles, engines, and equipment to reduce emissions and improve air quality.

If you are referring to auxiliary or reserve fuel tanks that are added to vehicles, they may be subject to certain regulations regarding their installation and operation. Here are some key points:

  1. Fuel System Modifications: Any modifications to a vehicle's fuel system, including the addition of reserve tanks, must meet CARB’s emissions standards. The system must not increase evaporative emissions or compromise the vehicle's existing emissions controls.
  2. Aftermarket Systems: If the reserve fuel tank is an aftermarket modification, it could require CARB approval. The manufacturer or installer of the reserve fuel tank may need to provide documentation that the modification is CARB-compliant, including how it meets emissions standards.
  3. Fuel Tank Size: California has strict rules about fuel tank capacity and fuel storage to reduce pollutants. A reserve fuel tank that increases total fuel capacity beyond what is approved may not be allowed unless it’s engineered and certified to comply with CARB standards.
  4. Legal Installations: For vehicles that are street-legal in California, reserve fuel tanks must be professionally installed in a way that prevents fuel leakage and complies with CARB’s evaporative emission requirements. If the modification is found to cause higher emissions or fails to meet CARB’s specifications, it could lead to fines or penalties.
In short, the legality of reserve fuel tanks in California depends on the specific design, installation, and emissions standards compliance. If you're looking to install a reserve tank, it’s important to check if the product is CARB-approved or if it needs any modifications to meet the state's regulations. You may want to consult with a licensed installer or check with CARB directly for guidance on your specific situation.

Good summary above. Another question, how would the factory fuel gauge and range calculation work? It would be very nice if the digital gauge noted 600+ miles after fill up. That alone may be worth the investment price and mitigate the fuel economy anxiety.
