What IS This Cannister?? (1977 BJ40)

[honk]

The tank you see is mounted to the left side frame behind the vacuum can (I'm guessing on that). That label isn't readable but the first letter is a 'J' and there is a hose connection to each end which puts the thing into the fuel supply line from the fuel tank.
It's not OEM as nothing resembling this appears in either the chassis or the 'B, 2b, 3b" engine fsm's. Also it has hose clamps like you'd buy of a rack in any auto parts store instead of Toyota OEM clamps.

Darned if I can figure what it is, though I could think of a few things it could be.

Anyone recognize the thing?

Ja think it may be a booty water seperator without drain???

Maybe a fuel heater... kinda looks like one I just saw on a video this week...

A water seperator? AFAIK it's got only the inlet and outlet that heads to the injection pump. Is there a type of seperator that works without a way to drain off the water? I know some people in another site who' like to hear of that if true.

A fuel heater? Pretty big for that, isn't it, and it doesn't seem to have an electrical connection or coolant connection, but I'll look at it again with that possibility in mind. It WAS in the north for awhile, after all, and there's a block heater installed.

Looks like a simple inline fuel filter. You throw them away after a few years.

Are you kidding?

If so it's the biggest filter aside the spin on cartridge type that I've ever seen!

Is there really such a thing as an inline closed filter that's about 10" long and has steel mounting brackets? Actually I'm thinking that you're right - are filters so big that are like this something that you've worked with on some kind of equipment, Moose? Like on locomotives maybe

Noz!

There should be a small canister with a drain on the bottom to drain water out . I would get rid of that monster and install a good water seperator or this thing might let you down.

do you have a brand and part number?
i looked at it breifly when i had the truck and guessed it was a feul heater of some sort...
cheers

Hi Wayne,
No, the only marking looks to be that label that's shown in the picture. It's no more readable in person than it is above.

I'll get under there and maybe drop it down for a closer look later. Right now I'm trying to squeeze out the last drop of backward seat adjustment by drilling and cutting and of course hammering. Yes...mostly hammering, .and loudly too.

Well, if there's no power going to it, it's not a heater. If there's no drain on it, it's not a water separator (unless it's a disposable unit with some sort of dessicant inside).

The fuel filter on my Ford F250 was 5" long and 3" in diameter. I think this filter is from a tractor trailer, and would therefore be huge. Have you ever seen a Peterbilt's air filter?

If the vehicle was up north it may be a huge filter. When diesel hits extreme cold it seperates as you all know but the wax becomes a problem at low temps. This may have been a way to remove the wax in large fashion before the next filter/pump and injecters. After running awhile the return fuel heats the tank and the wax is then recombined with the fuel as it goes by the huge filter. I have seen a similar setup and scratched my head for awhile till some gearshifter filled me in on it. The micron is probably massive so it will only stop the wax.
Kinda makes sense i suppose.

Damn thats a nice looking frame. You only came here to gloat didn't you!

Looks like a fuel filter to me, may be it came off a D8 CAT LOL?

I think you've got it with the idea that it's a wax filter for cold weather use.

Your post set me off on a little web search and although I didn't find this particular filter there are several on the market that do the same thing.

Wax in diesel fuel will gel in extreme cold, enough to clog a normal engine fuel filter. Although there are many fuel additives that reduce wax or the crystalization of wax in fuel, for continual cold temperature use a prefilter designed to remove the stuff before fuel reaches the standard equipment filtration makes a lot of sense. I don't know the vehicle's use history in Japan, but I think that things get pretty arctic on the northern Japanese island - at least a look at a world globe indicates that it could get mighty frosty there.
so I'll leave the thing inline as a relatively benign feature. It did get down into the 20 degree above zero range here a couple of winters ago.

As for the frame? You know, that's one of only two places on this frame where any sort of paint flaw appears. When I saw this photo enlarged I thought "Oh, no! It HAD to be where the worst part of the frame shows!"
