Do you have it setup to automatically transfer fuel or do you do it manually with a button?
I am very interested in one of the aux tanks for my LX. Also, since the LX has AHC, the extra weight won't affect ride height.
No, there is not a way for an autotransfer.
Basically it is a simple manual setup.
I wait till I see if I am at a half a tank (or whatever) on my main tank. Then I push the button on the digital switch / gauge and see the red light turn on. You can also hear the pump going. It is a slow transfer. Seems to go about 5 gallon per 10 min...so 1/2 gallon a min.
When I notice the main fuel gauge get full, I shut off the pump. Easy.
If I let it go till it was totally full, the pump would get VERY loud, therefore indicating nothing was going through the pump. I prefer not to do that.
When I filled up the aux tank it took 46.5 gallons at a cost of about $170-$180.
The main tank of 19 gallons cost me about $80-$90.
Now is it costing me MORE to fill her up? Nope.I just fill up now once every 3-4 weeks instead of once ever 3-4 days. So far my gas millage doesn't seem to be affected.
Now, I do SUGGEST new brakes, especially Bjowett's big brake upgrade. You are carrying around 400-500 extra pounds (when filled plus the cost of weight of the blank tank).
I have driven fast around corners and don't notice and sloshing or anything. As well I shouldn't, as the tank has baffles etc.
There were issues with the install.
It seems there are some major differences in the AUS and USA LC models.
The pipes need to be reduced and that is a PITA as there are not any direct reducers and had to be made. Out of the 4 days for the install, we spent almost 2 days finding the right fittings and making the correction reducers.
The carbon canister, ALL HOSES, and ANYTHING above in the spare tire area needs to be clear of any wires or hoses. There is virtually NO ROOM above the tank after it is fitted.
It is VERY close to the trailer hitch wire harness also.
We did a rhino lining on the tank before we installed it. Help protect it and you cannot see it at all. It blends in perfectly.
Now mounting it....they have it setup for 2 bolts in the front, 3 on each side.
Now this has to be another difference between the US and AUS models. The holes in the frame must be different. Only 2 of the three holes on each side matched up. Now they are not threaded holes in the frame. So they have an adapter to slide into the frame that has nuts welded to it. The first holes lined up..the second ones did not. So we had to drill them. Also we had to dril from the other side so we could affix the nut.
The third hole would not work at all as it would end up being drilled to the curved edge of the frame, which we would not do. Also they gave us grade 5 bolts VS grade 8...so since we were only using 2 per side VS 3...we upgraded to grade 8 (which we would have done anyway) 6 grade 8 bolts (2 per side and 2 in front) are more then enough to hold 500 pounds.
Now I had a custom exhaust on it already..so it had to be re-routed around the tank. Once the tank was installed it was hitting it, which is not good.
Do I suggest it....sure why not....but don't expect it to be a direct bolt in without any issues for the US models. It is not hard..just time consuming.
When it comes up to the Lexus mode with the AHC....I don't know if it's a good or bad idea...I don't have a clue what it looks like above and around the spare tire area. I don't know if the AHC has any stuff around there that would get in the way and could not be re-routed.
