i am on the road at the moment but if i were home, I could tell you the size.
you can also google that hose and one of the online Lexus dealers should show up with a part number, then you may be able to find the size that way...sorry I could not help more.

I used 1/4 inch aka 6 mm. It fit very well. I think I bought 5 feet from Oreilley's for less than a dollar. The only bad part is the clamps didn't fit right, so I had to buy clamps at O'Reilly's.
I didn't by the OEM pre-fit hose because the hoses were kinda pricey, but if I were to do it all over again, I'd probably go that route. Since the hoses go all over your engine bay, it is nice to have them molded and sharp cornered, instead of the hoses and aftermarket clamps, just lying there.

My newly purchased 2002 sc430 came back with an evap code after I had it in for Toyota service to replace the ATF. The dealer did a smoke test on the fuel system and found leaks in the the acordian hose and above the fuel tank. They are recommending replacement of the acordian hose, all the seals above the tank, and the ORV valve. The parts are relatively inexpensive, but the labor is brutal ... total repair cost $1,050.
The VSC light was on, but I reset it using the "jump wire in the OBDI reader" technique described in another thread. Oh well, I guess I can feel good about having new hoses and seals

i would check all of the hoses around the engine bay first.
i bet you find a cracked and broken hose on the engine, unless you tell me they have been replaced.
you also need to check post #11. Those hoses can come loose if you have bad motor mounts AND if you ever accelerate hard.
the engine flexes and it pulls those hoses loose...
just because you went to a dealer doesn’t mean they know all of the little issues with our cars...trust me they don’t. I am not saying your dealer is not an expert but most dealers are not.
i do understand if you might not be able to check under the hood and if that is the case, spend the money.

They did a smoke test and saw 2 areas where the smoke was leaking - above the gas tank and the accordian hose (which is located where the tank is filled, iirc). I'll have them look in the engine compartment as well.
Since they need to drop the gas tank to do this work, I asked if there was anything else worth doing "while they're in there", but they didn't think so. Can anyone here think of anything I should have them check while the tank is out? Any more hoses, bushings, or equipment that can easily be replaced once the tank is out?
I don't want to spend more money unnecessarily, but it seems to make sense to take advantage of the labor used to open things up.

here is a link to the image and all the parts in the fuel tank area.

I think 77213B is what they were calling the "accordian hose". I'll definitely have them check the engine compartment before they start pulling everything apart!
Yes, it would be great to have an advocate with me who knows these cars! I've taken my lx470 to these guys for several years and the guy who runs the service department is in my landcruiser club. They've never tried to upsell me into repairs, so I really don't think they are intentionally trying to mislead. However, I'm sure they don't see sc430s very often and they could misdiagnose the issue.

You may want to consider replacing the vapor canister. It is in that same general area. Of course you may not, I have never actually heard one go bad before. I had thought mine had gone bad because I smelled gas and had the 440 446 codes, but it turns out it was a hose in my engine, just like BGW outlined.

That was a very informative "just answer" thread. The dealer I work with did do a smoke test and found 2 leak areas. I'm thinking I'll ask them to do that test again and check the engine compartment before fully digging into a $1K repair.

Another thing to consider is you will get a P0440 code if you did not tighten your gas cap all the way

Thanks, I'll definitely check the engine compartment. That said, the smoke test revealed the existence other leaks. The question is whether I actually need to repair those leaks since it is possible they aren't all that bad, but I'm leaning towards doing it since I know they exist.

It has returned again!!! Thought I would share the easy fix...
Like Darryl and I have said, check those old vacuum lines.
this will give you a P0440, P0441 and/or P0446 code.

Yep, BGW is right. He pointed that out to me and said to look at the two hoses there on the driver side. I did and one was disconnected and the other loose. I just reconnected mine. (See my picture a couple of inches below the green cap.)

The EGR valve can throw those codes also if the hoses are off or bad. Mine was throwing codes and when I found it the part the hose clamps to was broken from the body. This part is unobtainum. With a small piece of metal tubing and judicious use of JB Weld, I was able to cobble it all back together. Its been over 5K miles and hasn't returned yet. Knock on wood.
