An update from FK.
Paypal shut of FK's direct business account, they refunded my money immediately and gave me the option to continue going through their Alibaba site (on which you can still use Paypal).
While a tad inconvenient, their communication was excellent.
Made the updated payment through the Alibaba site and I'm back on track.

Same… and just went through Alibaba instead.
 
Curious if anyone knows how the aux tank will function on fill up and how it affects the gas gauge,
Does the main tank fill and then overflow to aux?
Does it flow to aux first then syphon to main? If thats the case the gas gauge will read full for a long time then start to drop.
Would both tanks equalize levels while driving? If thats the case the gauge just moves slowly down.

Total newcomer to aux tanks so any info is appreciated as I anxiously await my shipment in 45-50 days.
 
  • Curious if anyone knows how the aux tank will function on fill up and how it affects the gas gauge, Does the main tank fill and then overflow to aux?
    • During filling, the tanks are positioned that both are filling in parallel, the aux may top off first, in which the remaining fuel will continue to fill the main tank till full.
  • Does it flow to aux first then syphon to main?
    • The the jet pump will continually siphon fuel from the aux tank which is effectively refilling the main tank until the aux tank is empty. The jet pump arrangement is the same OEM design that the international 300/LX gets.
  • If thats the case the gas gauge will read full for a long time then start to drop.
    • Your gas gauge will stay at "F" until you start using the main tank supply.
  • Would both tanks equalize levels while driving? See prior response. If thats the case the gauge just moves slowly down. See prior response.

Great info and thank you!
 
I was speaking at length with my local Lexus dealership service team. The like the look of the product and the function seems to be good (of course, many unanswered questions since noone has one installed as of yet)

Their biggest concern is safety, crash test ratings, compliance, etc. as each country has their own set of standards, would this meet those requirements in terms of safety and insurance?. That was the biggest question mark as that opened another discussion about the installation. They could do it, but they would need to prepare a document that would "remove liability" should "anything happen"

Insurance companies are shrewd practitioners of their own rules and justifications meaning that it being a modified part, it "could" nullify insurance coverage seeing that this is an untested product. |

I've reached out to FK for comment on this matter (and will report back on their response) but it has added a level of complexity and questioning to my motives for installing these now.

Any thoughts?
 
Any aftermarket part you install will be at your own risk. FK is very unlikely to comment.

That said, don't have the dealer do it if they are preparing any letter. I'd have a trusted independent shop install it.

Agree - no different from any mod. We take the risk. I would not have an issue signing away the dealers liability. I’d rather have the Lexus guys do it as they are solid at my store.
 
Why would an aux fuel tank be any different than a bull bar, sliders, rear bumper, on and on? Plenty installing those and having accidents and I haven't heard of insurance companies trying to deny coverage all together. Paying the cost for these mods is a different story though.

Well, for one there is nothing explosive or flammable inside a bull bar...
 
Before you post this kinda stuff you should read your complete insurance policy.
 
Anybody burns to death near your car all roads lead back to you. No umbrella or primary insurance will help, you fooked

I mean, if we are delving into extreme scenarios, I can easily see the family of someone you ran over with your bull bar suing you and your insurance for triple damages because you had a bull bar in the first place and that was the primary reason for the death. Going this path is like bindging all "Final Destination" movies. :)

Then they would be suing you for hitting someone, not for installing a bull bar. Unless that bull bar is illegal, in which case it would be criminal or negligent on your part.
 
Google:
“auxiliary gas tank for pickup truck laws”

Basics:
No gravity feed.
Manufacturer label.

Read this and ask the manufacture to label the tank as such and you should be good to go.

What is Legal?

Legality doesn't really matter here. It's perfectly legal to add a turbo to my car, but if it blows up my engine insurance won't cover it.

You must not know lawyers and the legal system. Do you really think there is no difference if I hit someone with or without a bull bar in the mind of a good lawyer? Even better if the bar was not crash safety tested, like many in the market. I am not talking about a criminal lawsuit; I am talking civil lawsuit for wrongful death, coming after everything you have plus what your policy covers.

So...you think that even if you didn't break any laws by installing the bull bar, you could still be liable for damages under civil law? 🤔

Sure you'd be on the hook for damages, but I that's because you crashed into someone. I don't think "installing a legal bull bar" would be the cause...
