I had a lot of sludge in the fuel tank of my digger and ran it dry of diesel due to there being no working fuel gauge. Got it all cleaned out and working again but got diesel leaks from the fuel lines where it bolts in. Been to a couple of farming workshops with a fuel line pipe which has an olive on the end. Should there be some kind of washer or copper joint that fits into the olive. It says on google to tighten it up but it feels tight to me and do not want to snap the threads.

I think it is just the olive which compresses a little on tightening.

Thanks do you get a special spanner for tightening them a normal one struggles to tighten the middle ones.

That could be useful for many jobs that crop up. I used your suggestion and found a cheaper set on Amazon. I have failed to copy over the reference but it is only about £26.

Numpty here couldn't even identify the fuel line pipe in your photo.

@ Mysty, diesel leaks from all the four fuel lines at the same time? This would be quite a coincidence. You mentioned a lot of sludge in the fuel tank, so it might be also a case of sludge and clogged holes in the fuel injectors. The fuel pump keeps pushing....Many YouTube videos about cleaning fuel injectors without taking them apart.

In theory, the slush from the tank should have been stopped by the fuel filter and never reach the fuel pump or injectors. These duel pipes may have olives and the pipes having been removed, be sure to clean the surfaces with a strong Martini before replacing. Some pipes have a brazed nozzle and if these are so, then they should be checked for cracks or broken tubes that may have happened while being removed. I don't know if this Kubota engine has a mechanical or electric fuel transfer pump because that would need to be checked for dirt. Not today though and it's too cold for that sort of outside work. Drink the Martini instead. edit. Looking at the photo again, it looks like it has a mechanical transfer pump just under the stop pull wire (great fix, by the way).

Crow foot spanners are ok but a little on the large size what you need if you have not already got is a "Brake pipe spanner" Iam sure the hydraulic machine guys will have larger sizes available. Have used a few in the past while fitting an outside toilet to a Saturn V rocket.

I'm sure Mysty's annual maintenance schedule includes renewing the fuel filter so the injectors will be fine.

I changed the pump and the flexi pipe to it. Opened up all the fuel lines which was a mistake not being a trained mechanic.

The stop wire was fitted by a pro before I bought it The mechanical pump has been bypassed its electric now.

Custom hand made bricodepot spanner fabricated using an angle grinder, plaster board re usable screws and a bit of recycled demi chevron. Im on an end of year budget, eat you heart out M Austin if you had half my talent you would be doing well.
