Hello. I am currently at sea on a friend's Moody 31.

The engine had cut out and we suspect bad fuel as the fuel is white

Sadly as I have tried to bleed it the pipe that joins the 3 injectors has snapped between the 1st and 2nd injector.

Can somebody assist with a part number so we can phone beta first thing in the morning. We are up the west coast of Scotland with limited internet.

All help is appreciated. The engine is a beta 28 ( BD1005)
 
Beta are very helpful and probably will be able to identify the correct part from your photo of your engine plate.

Your alternative is to find a Kubuto agent and they should be able to help as Beta engines are based on a Kubuto engine that Beta converted to marine use.

Hi

Your engine is a kubota d1005

You'll need the injector washers as well.

Make sure not to turn the upper nut of the injector only the bottom one. I assume you broke the pipe because one of these turned.

The top nut controls the pop pressure of the injector which is critical to proper operation.

If theres water in the fuel injection system you may well need to take all the fuel system apart and have the pump serviced.

Sounds like the leakoff pipe has broken, very low pressure in there so ok to use an ordinary piece of fuel resistant pipe to make a temporary repair
 
If it is from one injector to another it is NOT an injector pipe but the leak off assemble from the tops of all the injectors. It only takes excess fuel back to the filter, there is little or no pressure. A bodge repair with rubber/plastic tube or even epoxy putty will get you moving again. but please repair it properly when you can.
 
Now under tow from another member of the yacht club

Thanks for the advice. Was very easy to source the part from eBay with the Kubota details.

I think I have snapped the spill pipe myself or certainly helped it break if it was broken.

I was very wary of it and was using one spanner to steady the spill pipe while I attempted to loosen the top nut.

The stuff that came out definitely does not look wellIMG_20210808_094954_737~2.jpg

I know its not same engine - but that excess fuel pipe was cause of me losing my 3.0ltr Opel Senator ... apologies for thread drift.

On the Opel straight six - the injectors were linked by plastic pipe ... and it would harden and one would crack over time. Simple job for service to replace .....

So I gave car to service in Tallinn ... a one day job. End of day - still nothing heard. Got one of my Estonian guys to call service ...

'Boss - bit of a problem ... we need to go to service and speak with them'

So off we went to service .......... and as we drove into the yard .. I noticed a wreck ... looked familiar .... but shrugged it off and went to see service guy.

He took me to the wreck. It had caught fire and with all windows open - fire had destroyed the interior as well as exterior. They'd disconnected the fuel and stopped work on it to have lunch ... the apprentice unknown to the guys fancied the car ... got in it and stupidly turned the key. FLASH BHAM ... petrol everywhere ... flames shooting out of the workshop and he dived out through the inferno ... luckily only singeing hair.
Guys managed to put out the fire before tank blew .... but car was right off.

Service and I then spent that next week trying to find a replacement at Service expense. Sadly we could not find same spec .. it was FESTOO version with uprated tuning ... full wood veneer interior / leather .. the lot. We finally settled on a one year younger 3.0ltr top of range but of course it did not have FESTOO modifications.

Anyway - the mention of those excess fuel return pipes reminded of it ...

Your fuel is very contaminated. Before you have to rely on this engine in an emergency, get it all polished, the injection pump and injectors serviced and replace all fuel filters. Flush all the fuel lines too.

Left as it is you will get terminal corrosion in the precision fuel components = BIG bills.

Just a note ... that looks like classic emulsified diesel ... polishing will do nothing for it.

Just drain system .. check visually its clear and bright ... it may be that some water has with the pump pressure to injectors turned the diesel white as it emulsified ...

Agreed, drain it, and flush it! Lastly work out how it happened so you can prevent it in the future!

Please explain why.

Can it be guaranteed that the springs in the pump elements are all high grade stainless steel? I have seen lots rusted away due to water in fuel.

Why ? All fuel carries some moisture ... its impossible to have 100% dry fuel. Second - the act of draining and then repriming fuel system will effectively flush through.

I am not saying not to flush system ... having emulsified fuel /water leads one to ask why ... but also that the act of the injection system will pressurise the mix and can create that white result ... even diesel with low moisture can be forced to turn pale cream / white by aeration.

My lab was involved in solving the mystery of Off-colour Gas-Oil to Asian market some years ago - for that very reason.

Those return pipes are so easy to snap, I think they are disposable, good luck
 
It's been one of two things. The diesel cap isn't sealing properly or filling with cans.

We got caught a little low on diesel when one marina told us that diesel was for berth holders only.

A friend had some he had brought as spare but we think they may have got contaminated during his trip North.

The spill pipe should be here tomorrow. So I intend to go fit it now that the boat is safely back on its mooring.

Thank you. I do understand the water held in fuel situation, aircraft fuel being a case in point. where it has to be eliminated because it freezes.
I would expect the cause on a boat to be bad fuel handling or storage.
I have seen pump springs corroded to the extent that they no longer pump in circumstances where there was obvious water in diesel rather than a percentage of moisture trapped in the fuel.
