Outer Limits 4x4 Board

Hi All,

I hope you are having a relaxing long w/end.

I'm visiting the inlaws and the FIL's TD42 appears to be having fuel probs. When he came home it was idling like a pig and under acceleration would stall. This led us to believe it is a fuel problem.

We took off the fuel filter (it's big bugger compared to my TB42) and found that it was full of crap. It looks ike rust flakes from the tank. Off to Super cheap to get a new one but they are out of stock. Back home we washed it out with petrol a few times and put it back on and now it won't even idle.

The filter is a Ryco Z332 with a sender in it. Presumeably to detect water

My questions are as follows:

1. Is there anything special you need to do when you take the fuel filter off?

2. Is there anything special you have to do after you put it back on (e.g. priming it)? If so, can someone please describe the process to me as I have no idea about the TD42.

Anyones help is much appreciated.

Thanks in Advance

Gotta prime it dude... Should be a little white plastic bung you turn with your fingers, pull black plunger up and down till fuel comes out of the bung then close bung off.

DITCH THAT FILTER.

Thanks for tip.

Does the plunger come up far. This one does not appear to. It seems to be on a short spring. I unscewed the bung on the top of the filter facing the exhaust manifold and pressed the plunger it did expel some air from the bung at the top of the filter and I pumped for ages but no fuel came out. I assume that you keep pumping until fuel squirts out in a steady stream so as to eliminate air.


Sorry to sound simple but am i still missing something here?

Cheers

Keep pumping til the fuel squrits out... pretty much the same as doin the brakes - just keep pumpin til theres no air coming out and that way the fuel system is air free.

you should be able to give short firm pumps... pump till the fuel squirts.

Fill filter auto trans fluid 1st then replace.
Loosen bleed and press button for whats its worth.

Bazzle

must keep in mind people that if motor had been turned over with air in the system then the injectors may have to be bled depends how much air was pushed through
Or am i off the button ? Can air be pushed through the pump?
I agree with blackmav ditch the filter go out tomorrow and buy one from repco or truck spares or somewhere
Am also wondering if the petrol could have posibly caused something?

I just put a new filter on my TD42 and didnt have any diesel to fill the new filter with so just bunged it on dry.
I primed it with the hand primer a bit then just cranked the bastard til it went. It ran a bit rough and wouldnt idle for the first minute or two but other than that was cool.

Have you tried driving it for a k or 2 to see if it settles down? it may have petrol/air in it somewhere?

Many thanks for the suggestions.

We finally figured it out. For those who have not done this before here is what we did.

1. unscrew filter.

2. fill new filter with diesel.

3. screw new filter on.

4. open bleed screw at top of filter

5. press plunger on top of filter (after 3-5 presses diesel squirted out)

6. once diesel squirts out close bleed screw.

We also bled the fuel pump. which is a similar process.

1. loosen bleed screw/nut on top of fuel pump.

2. press plunger on top of fuel filter until fuel squirts out.

3. tighten bleed screw

4. Start car (Woo Hoo!)

5. Have a beer.

Thanks for everyones help.

Cheers

Could always cheat like I do, instead of using the hand primer, I used compressed air into the fuel filler (with a rag aoround it), until it blows fuel out the bleed screw.
This seems to prevent any air locks in the system.

Mine didn't even do that. I:

1. Drained the filter with the drain on the bottom of the water trap (initially difficult due to the amount of crap accumulated in the bottom of the trap).
2. Removed the water trap and cleaned all the gunge off it with a toothbrush and the diesel I drained out of the filter.
3. Removed the old filter (which was so old you could only just read the writing on the outside of the filter body!!).
4. Put the new one on without filling it in any way.
5. Put the water trap back on.
6. Bled the filter with the pump on the top until *all* the bubbles in the fuel coming out of the bleed bung were gone.
7. Started the engine and drove around the block with no rough idle or anything untoward.
