Argh! It's worse than I thought!

[Island Moose]

Not only are all four of my injectors seized solid, the fuel that leaked out of them when opened looked like chocolate milk. My fuel filter/water trap hasn't been helping, so I need a proper water separator ASAP.

I have to wait until Monday or Tuesday for new nozzles to come in to Action in Nanaimo, but I'm now wondering whether I should just get new injectors. Where can they be purchased?

Also, who makes and sells affordable water separators? Should I be concerned about the rusty color of the fuel or will the separator take that out along with the water? Should I install a third filter "in-line" between the tank and the separator or the separator and the factory filter?

Damn...there goes $500...

[crushers]

if it is that bad i would pull the tank and get it flushed, flush the lines, install a water seperator (factory or aftermaket) and run some good cleaner through the pump and lines. otherwise you are doing a part job which could come back to haunt you ( and of course that will be the most incovienent time possible...
just a suggestion.
cheers

[Island Moose]

Well the fuel coming through the line is clear enough, I checked it when I changed the filter. I think the debris got trapped in the injector, and the water must have corroded it. I will indeed find a water separator, surprised one was never planned for in the factory.

Is there a drain at the bottom of the fuel tank for purging water/contaminants?

[crushers]

if memory serves right i do believe there is a drain plug.
the rebuild shop should be able to tell you if the injectors are too far gone...

Your BJ70 doesn't have a factory water separator?!?!?

Neither did my 86 hj61.

[Greg_B]

You should have a water seperator in the engine bay, mounted on the inner fender. Unsure which side it will be one with your RDH 3B, however it will be an approx 2.5" diameter canister about 5" tall, with a 10mm bolt on the bottom. Loosen the bolt to drain any water out. These seperators are typically wired to a light on the dash, and have a float that activates the light when water collects in the seperator.

Hope it works out for you Moose. I just picked up my reman injectors today. New nozzles, seals and reset pressure. The shop did a good job but I had to get tip gaskets from toyota.

[Stone]

4Wheelauto (Alberta) has the reman injectors and the nozzles in their catalogue. I've bought a couple of things off of them and they ship fairly quick and are very helpful on the phone. Their prices seem to be competitive enough, maybe a few bucks more than some others. If they have them in stock, they usually send it DHL and it shows up at your doorstep PDQ.

OK, maybe everyone will tell me a fool... but, read that :

I've been in a Diesel shope to buy a new water separator. The mechanic told me that it's not necessary to fix a new one (my water separator is now by-pass) because the Diesel quality is now better than the 1983 Diesel. He give me for exmple is 2003 TDI VW without water separator. But he also tell me to change the diesel filter all the 5000km.

So, now my 3B work good and I don't see any problem at all.

Any comment ?

[cruiser_guy]

I personally would NOT run a diesel without a water separator. It's not just a question of diesel fuel quality but also how good the underground tank is where you fill up, how good the seal is on the top of the tank where the tank truck fills it etc. etc.
Unless you KNOW the underground tank has no leaks, the tank cover has no leaks etc. etc. then you are asking for trouble.
A little water in your injectors can ruin your whole day!

[Greg_B]

I would not run without at least the stock seperator. I have picked up bad fuel twice, and drained water.

[DieselROCKS]

I hear that.....its real easy for a gas station to get some water in their tanks. Plus a water separator can't be that expensive. Header over to a farm dealer

As for 4Wheel Auto in Edmonton....great guys over there, I've gotten lots of parts through them. I have the parts in less than a day when I order through them with the cheap shipping and I live in MB

OK what about to plug back my old separator. No diesel pass trough since 2 seasons.

I will listen to you...

Is there have a special procedure to use it now and plug it back ? How can I clean it ?

I know I can't open it because I already try.


And ho yeah... I forget to tell you... for the water in the diesel. I use a additive in when I fill my truck. But I know... you will tell me it not enought.

[cruiser_guy]

If you can't open the bolt at the bottom of the separator then you need a new one. And you're right, the additive is NOT enough. If you're the poor bastard that gets the dregs at the gas station you might have a tank of water (it's happened before to my parents and others I know in Canada). The additive takes care of trace amounts of water.

[David*BJ70]

I can open it...

I plug it back and that's it ?

Do I have to care TO CLEAN IT ? I suppose yes ? Pass so diesel in ? I suppose I found some residus inside ?

[Island Moose]

I have the factory fuel filter/water "trap", but the injector guy says it's nothing more than a trap, and that a lot of water can get through it. Mine also has a pump on top for priming/bleeding the system. He's apparantly right, as water ruined my injectors over however many years.

It won't hurt to have a proper Stanadyne or Racor separator in the system.

The water seperater that comes stock is not part of the fuel filter Moose. They are two different items, and in two different locations. All the 7* series 3B or 13BT trucks I've seen has the water seperator on a fender apron, then the fuel goes to the fuel filter, then to the fuel pump (gear driven off the engine block and has the primer pump at the top), then to the injection pump.

Can you snap a pic of your unit? I've never heard of the the B series having the filter that has the pump at the top. If it's the one I am thinking of we've a few of those units at the shop, however they came off HZ or HD-T trucks afaik.

Your injector guy is correct though...a good Stanadyne or Racor filter/seperator would be nice! You can get ones that heat the fuel, and maintain the clear bowl at the bottom. I've yet to find a good location to mount one on a BJ74 though.

Honestly it is Greg, I just bought one. It's on the right side of the engine bay, it is a pleasted paper filter with an opening at each end. One end screws to the housing, and a float with a switch goes in the other end. As the water is trapped, the float eventually signals the dash light to tell me to empty the trap. It's a Japanese - spec 3B-II, and I'm told it's unlike the ones sold here in North America.

Problem is...it ain't workin'!

[Greg_B]

Interesting Moose. We've a japanese 3BII core at the shop and I thought I saw the filter in the usual location. I am there for a bit tomorrow and will double check...if I remember!

gb

[Stone]

There is a paper element type filter that the FSM mentions. This is the page:



Would you be able to post up a pic of your filter/water trap contraption that came with your 3BII, for interest sake, Moose? Thanks.

[Island Moose]

[crushers]

that is the same as the 1HZ and the 2LT filter housings...

[Stone]

Interesting...thanks Moose! So, Wayne...that ragtop BJ70 that you'e expecting is probably going to have the same setup?

[Island Moose]

If I could find (or you guys could suggest) an in-line primer pump of some sort, I would eliminate the factory filter altogether, get a smaller micron filter (10 micron?) for the new Racor and hook the Racor sensor up to my dash warning light. However, I have no idea how I would prime the system without the factory housing.
I'm glad I got one with a 24 volt heater...I think it will help with cold morning efficiency.

[Greg_B]

Is the 2LT a rotory injection pump? I wonder if this is an inline vs rotory injection pump fuel filtration Toyota design thing. My 1989 inline injection 13BT BJ74 has the standard paper element mounted on the engine, and the water seperator ala BJ4*/BJ60/BJ70/74.

Racor does have a filtration unit that has the primer pump on top of the filter like your stock setup. We have one on our test bed for firing 1HZ/HD-T's.

i will know in a couple weeks but chances are, yes...

Does the filter light ever come on? All dash warning lights should be on when you start the truck and go off once it starts. If the light never comes on..... maybe it's burned out or some idiot disconnected it.

[Island Moose]

It works, I tested it and changed the bulb last week. If I'm right and it does a poor job of trapping water, then I wouldn't expect it to ever fill up and trip the float switch.
