I see on the back of the latest G Wizz that Eddie's truck has an extended fuel filler. I've never seen this in the metal. Can anyone tell me if this is something that can be attached to the existing short filler or is it a replacement part.  My 280GE has the extra fuel tanks in the wings.  Would the right tank need to be removed to have the extended neck brazed on or is it a twist and lock attachment like the filler cap? The bottom of the filler opening is a couple of inches below the tops of these tanks meaning that they cannot be filled completely.  I don't know why it's like this as it doesn't make any sense to me - anyone got any thoughts on this?  There are breather pipes to both tanks so they would both be capable of being fully filled if the filling spout went higher.  This would be a significant advantage for me as the extra few litres would enable me to make the run from west Pembrokeshire to Cambridge without refuelling at a motorway service station - within reason any money spent on the filler will be recouped by not spending extra money on motorway petrol.  I've tried to look into this question by looking at the russian epc but its not helping.

Re: fuel filler neck extender

Howard is the expert on these military extended fillers. He looked in to these in huge detail. Of course that was back in the day when he had time. Now he is far too busy on Land Rover forums diagnosing faults. I have told him the fault is in his head, and going to the Dr's would be more beneficial then LR forums. :)
I'll e mail him a link to this, see if he can help with the extended filler.

Re: fuel filler neck extender

Hi

Would assume it is something like on this attached EPC picture and it will replace the Right side tank?

Will confirm or give options later

Re: fuel filler neck extender

Thanks Gav.  Don't really want to replace the right side additional tank, just want to extend the filler and these epc pics don't show the extra tank.  I don't suppose there's anyone out there with a G that has both extra tanks and an extension???????

Re: fuel filler neck extender

Hi

It appears from what i can see on EPC that there ae two options..

The first that is no good for your requirements, is an extended filler neck to replace the right side additional 15ltr saddle tank, therefore losing capacity.

The second, that would be OK is a new right side tank with an extended filler built in, giving access to extra capacity. It looks however that this options has long since been discontinued as it was only really available with the single extra tank and the second extra tank made it obsolete.

There were in true MB style 3 different versions of this listed, dependant on serial number.

MB Germany list a note next to these part numbers as no longer available, please make an alternative yourself!

It would i guess, not be too difficult to either get an extended portion welded in to your neck and retain the original cap locking section or design and make an extended section that locks onto the original cap locking section and duplicates it again for the actual cap?

All sounds a bit more trouble than its worth i guess, but up to you?

Re: fuel filler neck extender

Will check my 'Danish' militar 460...it has the standard nato type extended filler...will check the connection and extra tank.

My opinion on this widely seen factory fit is that it is
 unattractive.

The answer is either put up with what you got or go to a plastic tank upgrade.

Also worth thinking of: fit an economical 605 engine like they do in Holland

Re: fuel filler neck extender

Hi

Tony's looks like it left the factory with a standard steel main tank only and a standard filler neck? Does not state that its extended?

Factory number A460 470 06 20

No use in this quest anyway....

Re: fuel filler neck extender

Apologies for my late arrival to this thread. When I first read it a couple of days ago I had to search the house for unopened post to find that the magazine had arrived and featured my son on the back page. He was NOT impressed ;-)))) and got me a walking stick for Christmas as payback. I can't wait to see the feature in the next issue.
I bought the "goose neck" on Ebay.de for about €100 in an auction. I do not know if they are available new. It is the same as #19 in Gav's EPC document. The original turns about 45 degrees after exiting the body to point to the right side of the vehicle. As I already had the ladder fitted this would not work for me. I had the pipe cut and rewelded to point straight up as you can see in the magazine photo. This is useful for refilling with a jerry can when needed.
I have the 96 litre plastic fuel tank, the one without a pass through for the rear exit exhaust. I have modified to side exit. The 92 litre plastic tank is the one with a pass through for the rear exit exhaust.
When I was fitting this all together I looked at the option of also fitting a right side auxiliary tank and concluded that with some cutting and welding it could be made to work. I did not proceed with this option at the time because all the aux tanks I have are rotten and a new one would have cost €400++ plus all the modifications needed for just another 15 litres capacity. Standard jerry cans hold 20L and my rear bumper carries one.
With a standard factory setup of the 65 litre steel tank and optional two 15 litre steel aux tanks, if you remove the RHS tank the LHS tank cannot fill (open to correction on that). Also the aux tanks are a rot magnet, terrible design, a huge problem on UK (salted) vehicles.
If extra range is needed I would go the whole hog and discard the steel tanks and fit the 92 or 96 litre plastic tank. These are very expensive new, about €1700 for the whole kit, but can be found on any breaker G from 1988 onwards. They come up on Ebay.de fairly often. A petrol G will need a tank with the cavity for the fuel pump (maybe the pump can be relocated?). A diesel G can use all plastic tanks I believe.
I find my range now more than adequate. 
Eddie.

Re: fuel filler neck extender

Thanks guys for the input.  Obviously this is less straightforward than I had imagined and I may just have to live with it as it is.
I agree about the auxiliary tanks being prone to rot, mainly on the top surfaces which you can't get at and which aren't covered by rubberoid as the lower surfaces are.  I've had them out and covered the tops in glass fibre.  While they were out I noticed that the tubes that drain rainwater from the rear air vents end quite high up inside the wheel arches abutting the rear three quarter panels that we all recognise as prone to rot.  This keeps the inside of the rear panels wet and it seems logical is to extend the tubes with some plastic pipes.  This keeps the water off the rear panels and the lower ends of the pipes can be fixed with cable ties to the outer ends of the rear mudflap brackets to stop them flapping about - rear panel rot is well recognised so I don't know why the shortness of these tubes hasn't been previously mentioned as this small addition can only help the situation.
