Fuel Smell (1 Viewer)

[1994LCNM]

Hi all,

So over the last week or so, when I come to a stop and exit the 2003 lx 470, there's a fuel smell and its getting stronger. I have a small leak in the exhaust after the cats on a weld, but there's no way it's causing this smell. I think it's the charcoal canister?????

I've been looking at how to replace this as I think it's the issue and the smell is coming from it. Is there a diy thread for this part somewhere? The canister isn't located under my hood...

Thanks!

Update: I heard gurgling sounds coming from thr gas tank. I opened the gas cap and tons of pressure was let out. Gas tank was really hot as well.

Any check engine lights or codes?

Evap canister for your year is under rig near spare tire.

Most likely bad valve or gas cap.

Charcoal Cannister Valve

Hello All, my 2000 year 100 series starts hesitating on pedal throttling, and sometimes doesn't accelerate at all, on advice from the forum, I dismantled and cleaned the throttle body, same problem, I replaced the TPS sensor on the throttle body and the throttle can accelerate now but its still...

There is testing procedure in FSM

Improved FSM downloads

Hey mud, I'm about 6 months in on owning my LC and absolutely loving it. Really wanting to do my own maintenance, so I sought out the FSMs. A quick search here lead me to the pdfs for a 2004 LC. Those were great except, like many of you have experienced, they are all out of order. Everyone...

No check engine lights or anything. What valve?? @kbfj621989

Your fuel is being super heated. And that fuel that you smell is your fuel boiling. It’s that time of the year again that we all LC 100 and 200 including 80 series owners see and experience this. My simplified solution: insulate your gas tank first, amazon has a lot of industrial type single sided adhesive insulating panels. Cover the bottom part and the side where the exhaust pipe sits just a few inches away. About 9 out 10 times this simple approach solves the problem. Good luck and keep us posted.

@OEMGUY0720 it's getting really bad, its like a spark away from watching the truck explode move style...

It's gotta be the canister or a component (valve)??

I can relate, been there done that. Order yourself those thermal insulator pads, insulate your gas tank and take it from there.

Ok, VSV and insulting pads, ordering now...

First of all fix the exhaust leak! that could be heating up the fuel tank. Don't wait. Then look for other remediations to reduce heating up fuel lines and tank near exhaust and engine bay. There are many threads/posts explaining it.

also, do not top off on refills. depend on the autostop filler function to stop gas fill.

reason: apparently, overfilled fluid will back fill to the canister, saturating the charcoal in gas and causing malfunction. that's the way i understand it.

Sounds (smells) like a new Charcoal Canister (CC), is needed. They only get wroast, once contaminated.

If you've a stock 100 series. I not bother with extra heat shielding. I'd replace CC, make sure engine turned and A/T fluid good.

I'd also do a coolant service:

I've a 06LC w/192K I just bought. In reading history I found PO complained of engine temp raising when both front and rear AC on. Toyota Dealership diagnosed with clogged radiator fins. Recommended new OEM radiator, $600 for the US spec Radaitor plus coolant and labor. They should have added...

If a built rig, with bell pan. I'd then consider extra heat shielding and air diviters. Ones that shiels and force hot exhaust air, away from fuel lines and gas tank.

Does anyone have a good reccomendation for a aftermarket CC please, ty!

It seems to me that this canister on the 03 470 is used in other vehicles?
