Losing Diesel out of fuel cap

[VladTepes]

I am losing diesel out the end of the filler neck, past the closed fuel cap.

It's not a little bit either as when I was going around a series of corners on the weekend the bloke in the County behind me noticed it sloshing out 8O :!:

Now that I come to think of it, the cap has often been a bit wet or greasy with diesel but i never thought there was a leak, only assumed it was spillage from when I was filling.

There was also on occasion where fuel was dripping out while I was stopped but I put it down to (and it no doubt was PARTLY due to) expansion of fuel as it warmed.

In any event this is a problem :!:

One of the major issues that I se is that unlike a styleside ute or a wagon where the filler is up much higehr than the connector on tank, in order to allow one to remove the fuel cap from the filler (located under the tray) it is a fair bit lower - and the hose is much closer to horizontal. (It looks like mine may actually dip slightly as it comes out of the tank and then rise slightly to the filler).

Has anyone had this same problem with their traybacks :?:

Can anyone suggest any remedies :?:

Suggesting you hang a bucket off the filler nossle wouldn't really help much would it ?? style_emoticons/<#EMO_DIR#>/laugh.gif style_emoticons/<#EMO_DIR#>/laugh.gif style_emoticons/<#EMO_DIR#>/laugh.gif

Sounds like time for a new cap or seal or something like that.

[Captain_Rightfoot]

I just thought.. are there any hose clamps or anything that could be tightened?

[George130]

Havn't heard of this but I will watch mine in future. Mine definatly goes up though as I have aftermarket tanks.

[abaddonxi]

On the 120" I had a persistent leak if I filled up anything more than half a tank. It was a steady drip at a time.

In my case it looked like a hose thing, something to do with the point where the tank joined the hose.

I ran into a fella in a Defender when we were both filling up and he had the same thing. I assumed it was a standard factory fitting. Took me 6 months before I filled the 130 all the way and wasn't I surprised.

I didn't end up doing anything about it except carrying a spare jerryfull around, it all looked like too much mess and drama.

Cheers

Simon.

I fill mine to the brim each time. the dockets are a bit rude these days though.

Blocked breather hose maybe.....

[VladTepes]

how to unblock the breather hose ?

And if I were to want new hose - where from and what would I order ? Is it a particular type / size etc. (Fuel and breather hoses) I don't want to have to take it off to measure it as I will be going to the hose buying place in the car itself.

[Captain_Rightfoot]

Maybe the first thing to do is to fill it right up and then park on something with the filler cap down and see where it's **really* coming from?

<span style="color:blue">make sure that when your filler cap is fitted there is no freeplay....
also check the seal under the filler cap to make sure its not split.....



if its a screw on filler cap.....make sure its not cross threaded</span>

[sclarke]

Ahh the old spilling fuel out of the filler trick.....

I've found in the past its due to the cap being left on the bowser....................


Sorry. Had 2..... i see it so often....

Hi Vlad

A mate has a 110 trayback and yes I have driven behind him in on rough roads and he has been losing fuel from the cap. I only saw it once when we had filled in Broome and were heading up to Cape Leveque. He probably wanted to make sure he go in as much as possible and between expansion and topping up went a bit far.

Nothing much to contribute but do you top it right up or stop when it clicks perhaps rounding up to the next litre?

I got him on the radio and said he was dropping fluid, we soon saw it was diesel out the cap. He said "that's Defender fuel economy for you, every now and then you have to stop and let some out"

[CraigE]

Vlad,
if its the fuel cap and it is the old type not the large plastic screw type but the flat type and you need to replace it let me know as I have a brand new one sitting at home. Locking type with keys. Defender locking fuel cap part number RTC4740, may be for a V8 not sure.I ordered one from the UK and they sent me the wrong one and I cant be bothered freighting it back. You can have it if you need it, you might be able to help me out with something later. If it is the plastic large screw type then an Aunger LC91 should fit from Supercheap, it is what I have on my Fender now and at $14 compared to LR's $90 qote is a bargain. The only thing is they do not lock like the LR ones which keep twiting until it clicks and locks. The Aunger ones are turned until they click and the the key must be turned forward to lock.

[VladTepes]

Its the type which when the key is in it, it won;t come out unless the cap is locled. It has two tabls that slot into gaps in the filler neck end, and then twists to close. Tunring the key then locks the cap, allowing the key to be removed. It's a great system - can;t leave the cap behind as you can't start the car without the key. (This assumes you have both keys on the same key chain of course).

D_Zook: What seals ? When I look at the inside of the fuel cap I only see metal (ie on the face that would be up against the fuel filler neck). Is there supposed to be some sort of rubber ring or something in there ? Perhaps someone can look at theirs (older type not screw in type) and tell me.

I have no idea what other seals you might mean.

older type should have a rubber ring against the metal you can see, so it ends up being metal in cap to rubber to metal in filler.

So that is the fix.... Zook is on the ball once again...

[VladTepes]

Hmm - and I'll bet that rubber ring is not available seperately.

make one from cutting an inner tube of a car or 4wd....
might have to make several layers to get the right thickness.

[DEFENDERZOOK]

<span style="color:blue">what about the elcheapo cap from super crap....?
that might a have rubber seal that fits your cap......

heaps cheaper than a new cap from land rover.....</span>

[DEFENDERZOOK]

<span style="color:blue">is there movement in the cap when its on properly....?
ie....is there any freeplay or does it sit nice and tight...?</span>

[VladTepes]

Doesn;t seem to be loose, but then again I've no 'standard' to compare it with.

[VladTepes]

Well I've had the tray rails cut away ( a bit thereof) and moved the fuel filler higher so rather than being more or less sideways from the tank 8O , there's now an upward curve to discourage gravity from having its evil way with the diesel.

"Gravity is, after all, a hard habit to break". (Terry Pratchett)


The seal in the fuel cap itself is there but NOT good. And naturally they don't sell the seals seperately. So the options are either:
1. Buy a new lockable one from Land Rover ($100 and the inconvenience of another key - and I'm told they are rubbish anyway) OR
2. Buy a 'generic' brand LR fuel cap- non-lockable for about $40 (although if ever fuel needed locking up it's these days) which has the disadvantage of being easier to forget and drive away without putting it on (although at least they apparently seal well) OR
3. Trusr that moving the filler will have been enough and don't spend any more $ unless absoilutely necessary.

I'm taking option 3.

[abaddonxi]

Or - land rover locking cap on ebay.co.uk

http://cgi.ebay.co.uk/Land-Rover-Locking-P...1QQcmdZViewItem (http://cgi.ebay.co.uk/Land-Rover-Locking-Petrol-Cap-New_W0QQitemZ4586244434QQcategoryZ31348QQrdZ1QQcmd ZViewItem)

A lot less cash.

tis cheap alright !

Anyone ever paid for an ebay pourchas in the UK or US ? How ?

[DEFENDERZOOK]

<span style="color:blue">post a pic of your fuel cap for us all to see....


and someone with the same cap (without the leaks) can post a pic of theirs
then you can see if there are any differences or problems......



seals perish and springs break.....

there is obviously a problem somewhere....repairing is always more fun than replacing......
more satisfaction knowing you did it yourself...and you learn how something else works on your rig.....

a good thing....</span>

[VladTepes]

Its just like the ebay one - if someone has one and can post a few pics of the INside of it, I will do the same when I get a chance.

[DEFENDERZOOK]

<span style="color:blue">looking at it from that side it looks the same as mine....

it should seal tight and hold pressure as well to stop fuel vapours escaping....</span>

Get a paypal account http://www.paypal.com/au/ you need a credit card. Most eay traders will accept paypal. Of course they charge like credit cards for currency exchange and the rest. They charge you currency exchange, they charge seller for transaction. if you have a problem with the seller paypal will probably refund. The other good thing with paypal is that once you've made the payment an email is sent to seller and they know that money is there, so fast for posting too. Don't pay by Western Union, very easy to scam.

I've bought a fair bit of stuff from US and UK and mostly not had problems. Problems have almost always been with loony buyers or scamming sellers, but most are genuine.

Of course if you're shopping for a Rolex, a Satphone, etc. you're on your own. Whole world of scams.

Ha ha ah?
