I'm considering the idea of putting a strip of neoprene around the gap between the column cover and the dash metal, if only to keep the dust out. I think it would look cleaner, installation-wise, as well. Is anyone finding the 60 series column looking too out of place in this dash?

Chris,

The fourth fuel vapor line does use a check valve, and then goes through the four-tube bracket.
From there it exits the bracket under the cab and a hose connects it to a metal tube that enters one of the floor crossmember supports.

I puzzled over this for some time. It seems that the Toyota engineers wanted to have the fuel system acclimate to the atmospheric pressure at certain times, but of course our environmental wizards could not tolerate the possibility of any fumes entering the environment. So......it looks like this fourth hose accomplishes both tasks....... sort of. It vents or draws when needed with the atmosphere, but the greenies cannot see it happening, as the tube enters the crossmember, never to be seen again!!

Anyway, that's my take on it.

By the way, super job on the finish assembly!!
 
Ah yes, the dreaded 'tube into the cross-member' mystery...


I do seem to recall something like that on my truck, but it was a looooooooooooooooooooooooooooooooooooooong while back that I yanked the tank out of there, and of course I took no photos as I stripped it all down, thinking that I would 'figure it out later'. And here we are I'm confused, at least some of the time anyhow.

I guess there isn't really much need to do anything with the line from the check valve - leave it connected to the 4-tube doohickey, and that's it. Well, i guess just for forms sake I ought to put a piece of tubing on the other end. I'll try and remember to do that tomorrow.
 
Is the fuel separator a 47 thing? I can't find it on my 45. Was it also common to the gasoline engines?

You are now officially me hero. The 47 is coming together so nicely it's scary. I don't think the 60 column looks too weird in there. Is it bolted in the final spot there? It kind of looks low, but that might just be because of the tilt. Either way, the 60 series column "looks" almost as right as a 40 series column, but with a lot of benefits to it. I like it. I'm tempted to try the same on mine.

Three cheers for the 47!!!

Isn't the fuel separator on the pre-1979 trucks located inside the cab next to the fuel tank? I thought so- I'm sure i've seen pictures of that, but I don't know the answer for sure in terms of specific cruiser models.

I'm not sure if the fuel separator is a diesel-specific part, however I am sure that is exists in other cruisers besides the HJ47 - I've seen them in BJ and HJ60 trucks for example. As for the gassers...????

I'm glad you like the look of the column - it was nearly a disaster as sub-project, as i was really stymied by the wiper motor problem for a couple of weeks. I'm still undecided about the steering wheel. It definitely will not be a stock unit, which at 16" or so, is simply too big, especially given the power steering. I'm pretty sure the central axis of the column is in the same position as the 40 series type, however the extra bulk of the tilt head and attached plastic housing does make it look a little lower. The steering wheel is still the part that gets in the way - my knees clear the column housing okay.

I'm looking at options, though so far I haven't been able to find a stock Toyota wheel that looks right and is sized right. I might have to go with a Grant aftermarket wheel or something like that.
 
Just a quick note:
The Sixties 45s had no vapor separator.
The Seventies 45s got them at some point, installed INSIDE the cab, for gassers, maybe for diesels.
The 1980 up 45s got them installed like Henry James on the OUTSIDE back of the cab covered with a sheet metal surround.

I suspect that when they became necessary for the 40s, they probably also became required for all production vehicles and would have been installed worldwide throughout the entire product lineup.
 
I can say on an American smogged 1973 FJ-40 the seperator was present. It was mounted in the cab. The fourth line on gas engines led to the charcoal canister mounted on the passenger fender down below the battery. From there a computer controlled vacum switching valve would allow engien vacum to pull the vavpors from the canister at certian times. These times, as I recall were during cruising down the highway and when the engine was warm. Other wise the fumes from the gas tank were trapped in the charcoal and did not vent to the atmosphere. The bottom of the charcoal cansiter had a breather hose to allow air into the tank as you displace liquid.

The three lines from the tank tap the tank at certian spots so the tank is always vented regardless of angle. The vavle thing had to do with one way travel of the vapors and liquid not escaping as I recall.

What I don't know is if diesels can even use a charcoal canister. Or if diesels even need a charcoal cansiter. I suspect possibly that the seperator was put on all cruisers after smogging was needed. But only the gas engines had a line connected to the forth line that ran to the charcoal canister. Otherwise, the fourth line is just dead ended for diesels. I would shape up a hard line, or find yours and run it up into the cab support like it was before. I think the object of this is to reduce dust and crap being sucked into the fuel tank.

Of course I'm speaking out of my ass, all I know is that my 73 had a seperator and charcoal canister. It was the second or third year they did that. My FJ-60 also has a very similar system on it, aside from more controls of the charcoal canister cleansing, and the fact that the vapors from the float bowl is also directed to the canister, rather than being allowed to be vented to atmo.

Lots and lots of other rigs had charcoal canisters, but I have seen very few with the seperator. I have the parts to put one back on my 73, finally, and will do so, as the expansion of the tank, espcially inside the cab makes for a fumy ride and will push gas right out the filler it too full on a hot day. I made my own seperator years ago, and it helped alot. Used a peice of hard line made up into a coil to act as expansion room, then just vented the tank under the hood. This does make for a fire hazard though, glad I found the used parts to fix it.
 
I'm starting to look forward more and more to each day, especially now that i don't have to do any more bodywork!!!

Just waiting on the painter now to do the doors and hood tonight, and then the roof and bezel soon after.

So, after a couple of hours of sanding priming and more sanding this morning, i worked away at hooking various things up on the truck. First off, I glued some 1/4" foam to the heater blower motor, giving what seems like a decent seal at both intake and outlet.

next I s-c-r-a-p-ed the old foam off the main duct and glued some new foam into position. I'll leave off putting the duct in until I have the wiring harness back in place. And what is it with this forum and the blocking out of the word c-r-a-p with '****', even in words like 's-c-r-a-p-e'??

here's more. I located the old gas tank rubber packing strips for the straps - good thing, as they are no longer available from Toyota. I also packed a little more felt under one end of the tank to firm up the mounting a bit.

Thanks for the info - I'm not so familiar with the gas engined trucks, so that was all news to me. I know that there was never a charcoal canister on my truck - the line just went into the box section of the cab support and that was all.
 
Another long day of reassembly. The doors and hood are now finish painted and came out really well. Only the roof and bezel remain, an they are ready to go, so no more bodywork for me to do, and no more blue to spray. It's all good.

Today i installed glass for the first time. It was nice to have the little 1/4 windows to warm up with.

Then I tackled the front windscreen, another oem part i got on ebay. It took me quite a while to sort out which way to orient the weatherstrip to the glass and opening. Once i had that figured, and wrestled the rubber onto the glass, it went in pretty nicely.

I forgot my camera for the afternoon however, so the next set of photos will have to wait a day or two. I made progress with bunch of different things, too many to list at the moment.
