Factory sub tank - sourcing and fitment discussion (1 Viewer)

Does this apply only to the LX?? That is if doing the similar on an LC 200 relocating the evaporator would not be needed.

The evap canister on a TLC/200 still needs to be moved, but in most cases the move to the right (US passenger) tire well is straightforward. Bend up a little bracket from flat bar, use the existing holes with weld nuts (these are used in the LX570 for the AHC pump). The electrical may need to be lengthened, the vent hoses work in situ.
There was a thread cross posted earlier in this thread where a non factory gravity fed sub tank was added and this is what they did on a TLC.

If you have an aftermarket bumper that has a mount in the right wing area, you'll need to factor that bracket into the calculation.

In my case, I have an LX570, which has an AHC pump in the right wing. I also have an aftermarket bumper which has a bracket in the right wing.

Does the evap canister vent at all? If so under the hood might be a bad place for it.

Did you change your exhaust pipe to dump out behind the tire instead of straight out the back? If so could you put the canister DS rear where the exhaust normally dumps? Or maybe that's what you were thinking in #3?

the canister is completely sealed. It does have a fresh air vent, but that is post scrubbing, post filter, and valved (normally closed). the canisters are often placed in the engine bay across manufacturers

I do have a side exit exhaust. The space between the frame is taken by the tank, and with my aftermarket bumper anything below the frame will get scraped off

Integrating anything into these modern vehicles is such a challenge. Best of luck as you break new ground.

 

[grinchy]

It is surprising how little room there is under and above frame level for such a large vehicle

Now 6” of snow in my ‘garage‘. Bought 25’ of 1/4 and 3/8 low pressure fuel line and a bunch more barbed joiners of various sizes. Leaning more toward putting charcoal canister under the hood if I can find a place for it. Already have a bunch of long run exterior Ethernet cable to use to extend the electronics.
working on a list of what to do in order.

Ethernet cable for the win!

 

[linuxgod]

If it's gel-filled exterior ethernet cable, that stuff will last forever. Regular PVC jacketed stuff breaks down and cracks over time, letting moisture in, but I used to run the gel-filled stuff to antennas when I ran a wireless ISP years ago and it would hold up amazingly well to snow, ice, rain, etc.

Charcoal canister Mock-up fits up by radiator. Probably have to move the power steering reservoir a couple inches, no big deal. Driving light resistor gets hot so I’ll bury that in the fender.

it’s a plan

Yes sir. Gel filled UV resistant bury rated. Also conveniently low resistance and has the required 8 conductors in it.

My US spec 2009 LX570 has anchor nuts in the frame for the two forward positions.
left position is not straight on, connects to the left Of straight a few inches.
right position is straight Ahead along body corrugation.

there are not nuts behind the sheet metal at the two rearward positions. I’m moving on to 8mm rivnuts At these two positions.

 

[grinchy]

Put in the two rivnuts for the straps.
also showing the other two locations

need to order some of these zip tie clips, they’re all breaking

 

[grinchy]

Pulled the charcoal canister. To get the green clips out I used a small flat bladed screw driver and then a pick in the center.
plug is pry out on the tab and pull.
used the hose removal tool I got that was on another thread for the purge line. Too easy.
only four connections.

Edit; Do not fully remove the green clips, they come up a bit more than 1/2 way; at that point the fitting can be removed.

 

[grinchy]

Air filter is just a friction fit up to the filler nozzle. Just pull it off.

put the tank up there for a dry fit but still need to figure out some wiring bundle relo in the back right corner. It does go in past my rear bumper brackets which is a relief.
the vent tubing looks to be larger than I ordered, I got 3/8 and this is looking larger. Since I plan to run all the way to front I don’t want to downsize, will Put the micrometer on it in a bit And figure out what is necessary.

<edit: 15mm ID (measures 14.5x mm) on the vent tubing, it's very thin wall corrugated tubing. OD is 17.5mm>

 

[grinchy]

The purge line is 5/16” or 8mm.

 

[grinchy]

Shouldn’t be a problem.
Nothing repositioned in this pic, just resting on the power steering reservoir

Where is the charcoal canister located on the sub tank trucks in the rest of the world ?

I don't think it is. US emissions are more stringent.

at front of main fuel tank somewhere
