Fuel Hoses - Puma 2.4 - Leak

Landy-Max · Apr 9, 2021

When I BRIM my tank (I totally brimmed it - really full) - I have discovered it leaks. - which I am led to believe - is either the main hose or the breather. I can see if main hose it’s easy to change - my question is - if breather - do I need to drop the tank - if so - is it a bastard to do ?

I have learnt that one should not brim the tank beyond the click - lesson learnt.

I rang to see if the hoses are available - main hose is from dealer. Breather is not. What do ppl do aside from salvage to replace breather?

I am hoping it only leaked because I brimmed it. But probably not. Hoses are 10 years old.

I am not very familiar with those late models, but if it is the same as the earlier ones, the breather is just a nitrile rubber hose.
Google it, you can probably buy it off the net by the metre. Measure the old hose for diameter and length first.
It may not be the hoses at all. Diesel is pretty slippery, and it may just be leaking out around the cap or through the cap breather.
Don't fill the tank quite so much, it may not happen again.

Not a job I've done, but the Haynes manual rates the job of removing and replacing the tank as one spanner. But they note that the tank has to be moved forwards after removing the nuts n bolts, and then drops out. They state this is ok on the 110 but they found it not possible on the 90 as there is not enough room to move the tank forwards before dropping it. So the body has to be lifted off the chassis and the tank taken out from above. On the plus side, the instructions note the breather pipe is removed before removing the tank, so take a look and see where it is connected, you might be lucky -----

I don't really know where the tank is on a Puma, but if it is anything like older models, I doubt you have to remove the tank to change the hoses.

Its at the rear, just in front of the cross member.

Are the hoses on the side, or on top? And is there any kind of access panel above the tank?

Just had a look at one on a 90, the breather hose looks like it goes to the top of the tank and is inaccessible without removing the tank first. No access panel above.

That is a bore. With the old tanks under the front seat, you could get to the top of the tank by removing the floor, it was just held in with screws.

I am doubtful that his breather hose has perished anyway, as they are not exposed to the sun, they last fairly well.

I'd agree with that. Probably just a case of overfilling (see attachment). Reading through the LR workshop manual, the breather hose is released from the tank before removal of the tank part way through the removal process. So it must be possible to remove the breather without fully removing the tank.

I had a similar issue on my 2.4 but discovered the breather hose had a split in it and fuel ran back down onto the tank so thought the leak was associated with the tank.
Easy fix I cut out the affected piece and replaced it with copper pipe and clips, as to replace the whole thing would have meant dropping the tank
