Hi all
Just a quick heads up regarding the fuel breather hose. I replaced mine today as it was cracked and splitting. I did not intend to replace the short piece from the tee back to the tank, but on closer inspection I noticed it was also split. How could Landrover use such crap materials, well yes they could and do in all areas, but for something that is virtually impossible to access on a 90 without major surgery you think they would have used a better quality pipe. The old short pipe feels a bit plasticky (if that’s a word) not supple enough compared to the marine grade one that I replaced it with. So if you are replacing the breather pipe and going to the trouble of gaining access, check the short pipe from the tee for splitting as well. Regards to all. Fletch. |

Hello sat13
Good advice... 
'Interestingly' I was at my local independent and they were replacing all the fuel tank 'plumbing' on their own 110 Not a single piece of Land Rover OEM Pipe Work went back in, all higher spec (used in stock car racing) replacement pipes were made up to suit. but this is the little fella that sometime gets overlooked...

This thread with now well over 30.000 views has so much useful info about a not so easy issue which virtually all Defender/Puma drivers will encounter about every 3 years or so, that I think Martin should make this a "sticky" in the Maintenance section.

New owner to 2012 puma 90.
Checked my breather under wheel arch. No cracks as far as I can see. Is it worth cleaning both filler hose and breather hose and applying some heavy duty tape wrap all way down to the chassis/tank? It would at least shield the rubber tubes directly from the elements. Yes it won't do much for the tank end of the breather tube. Any suggestions of what tape to use? Regards DrKaz |

What about wrapping the joints in Denso tape?
Cheers Andy |

Denso tape- never heard of it so googled it.
This stuff could work with a few loose cable ties to keep in place till it bonds and drys. Is it safe to be applied on rubber hoses? |

Greetings
Wrapped the fuel tank hoses with insulating pipe foam that plumbers use. This creates a waterproof barrier which will hopefully protect the evidently poor quality rubber from the elements and dirt.

I had a similar problem on my 2.4 Puma. The pipe on the top of the tank came off and consequently we spilt fuel on filling up.
The breather has detached on top of the tank and is very hard to access. Was able to attach a new length of hose with jubilee clip and drilled hole into the wheel arch to lead the pipe into a space above the tank. Problem solved. 90 Puma 2.4 Overland travels. |

I had the problem with fuel spilling out and a mechanic changed the hoses for replacements which would apparently "outlast the vehicle" but were tight to get on.
Next thing I knew even more fuel coming out when full and it appears the top of the tank where the filler hose enters had split! That required a second hand tank (and 800 bucks) but I noticed that the red "tight" hose used previously was absent... now I wonder if the this hose required too much pushing to get on and that split the tank? I'll never know but as the thing is now up for sale I don't care much. Good riddance to a vehicle ruined by both LR and Ford cost cutting. AlanH. |

I have a 90 my07, there is a breather on the inlet from the filler but also one in the nearside rear wheel arch. it looks original with clips etc. anybody know where that comes from (is it t'eed from the other side in the filler breather or is it totally separate) as it has perished and need replacing
thanks |

My problem had been spillage via the small tube teed off th e vent line. I took solutions from various parts of this useful thread to fix the problem. Firstly I opted for the 'cut a hole in the floor' approach to gain access to the top of the tank. It takes a lot of careful measuring and then even more careful cutting to get easy access to the top of the tank but it can be done quite neatly and later covered with a removable patch of chequer plate.
Next was to source marine grade fuel hose - much beefier than to original yet still can be fitted through the gap above the chassis rail into the wheel arch. Then the positioning of the silly little tee- off piece. Here I moved the tee right away from the tank and joined it in adjacent to where the big vent pipe joins the filler tube. The u- bend can be positioned in the wheel arch above e height of the tank and protected from crud with a cut off from the old breather pipe. Filled brim full for the first time in months and didn't leave he usual puddle of diesel on the garage forecourt - yippee |

^^ If I read you right, you positioned the little vent pipe very much the same as I did and also extended it to make sure there will be no incoming water or crud (see page 7 of this thread), correct? So far so good with me for sure.

you know, I think LR have the vent filter on the J pipe the wrong way around. Pulling my 2010 one off I discovered if you blow in the big end of the cone you get a reasonable amount of resistance. Turn it around and blow through the small end and it vents nicely. LR have the resistant big end stopping the pressure from leaving. Now in my mind it should be be the opposite. Slow and steady inbound as fuel goes down steadily, but also needs to be minimal not to attract dust and the like. Fast outward as pressure from heat or vapour expansion increases quickly. The way LR have it perhaps its why diesel finds its way to every weak point in the piping as the resistance in the valve is too great.
Of course my money box had the big end on the J pipe towards the tank, and when I cute pipe a whoosh of air came with it. Yes mine has diesel  all over the fill pipes, chassis, and fuel tank as well. After turning my vent around I went for a 30km drive, 15 of it on highway at around 20deg. The car ran fine with half a tank on board. When I stopped and took the filler cap off there was a slight inward breath, but certainly nothing that rivals the common outward whoosh. I drove home repeating the journey and let the car sit over night. In the morning I opened the cap and got a slight inward breath again. I know its inward as there is no smell attached to the sound. I was hoping for no sound at all, but figure there could be a couple factors that may effect the finding. Down here a front has just come in and temps are only 16 to 20deg, so there is not a lot of temp variation to cause more or less vacuum. And at the end of my J pipe I run air line similar to an air locker for about 2m. It does take a bit of effort to blow through it and I should probably upsize the pipes ID to reduce restriction. Thinking when the weather clears up I'll disconnect the breather extension and see how the tank breathes with a shortened intake pipe.
Its has been hot as hell down here recently so will also be good to see what happens on a hot day with half a tank. I'll report back when the weather gets organised. My Defender and travels |
