LX700h Factory Sub-Tank (2 Viewers)

[Oakleyguy]

I'm starting this thread to document my findings on retrofitting the factory 30L sub-tank to the LX700h.

I initially discovered the sub-tank option when looking through documents on the Toyota TIS system. Specifically this graphic:

I was able to locate the part numbers of the Gulf Council spec LC300:

Sourcing right now seems limited, as Partsouq is out of stock, but one did pop up on ebay for about $400.

Will update later as progress is made.

Is this petrol? How about the 600?

Yes; it should theoretically be the same for the LX.

Can you list all of the part nos. required to install and integrate into the system? Big help, thanks!

That will be the plan, I did some pretty heavy research last night on the charcoal canister and fuel vapor emissions control system using a variety of sources (including @grinchy's subtank install on the 200).

Good news it looks like truck may be prewired for the 2nd fuel sender unit, but I need the truck in hand to confirm.

I'll be posting up a PI&D on the system something in the next week or so.

Watching this for sure.

Thanks -- looking forward to your analysis--big fail to have such a small tank, and noway do I believe that the real world LX 700h mileage is better than 13-14 mpg. My 200 is barely there.

Real world LX600 mileage: 18 mixed driving, 22 highway. Very consistent, 50k miles and three years. I get almost 400/tank, usually fill up before empty, 340-360 miles.

Beats the 200miles a tank I get in my 200 around town

Long Range Automotive also offers a replacement tank for that 30L subtank.... increasing it to 80L (21 Gallons). This is for the Turbo Diesel (FJA300) though. Worth looking into to see if the available space is the same.

Great find! I'll add that into the research queue!

Posting the LRA instruction here for record.

The Long Ranger also offers a similar tank but 76L.

Minor updates above.

 

[stiffarm]

Can the tank be used for gasoline??

 

[CyanideRide]

Where would the filler nozzle go to fill up the tank?

 

[Oakleyguy]

The factory (and aftermarket tanks above) are integrated into the primary filler neck. There's a tee that splits the gasoline from the filler:
