THE PORTAL HUB - Pinzgauers, Haflingers, Volvo 303s and more!

We are trying to remove the gas tank on my sons 73 710m. We have loosened all the bolts and the fuel line but the tank is hung up on the filler connections and we can't see how to disconnect them. Anyone done this or have any input.
Thanks

The convoluted boot you see is for decoration for the want of a better description. In fact the real hose connecting the neck to the tank is telescoped inside. Gently pull down the convoluted hose after removing the clamp to expose the inner hose assy and clamps.

Once free you can pull the convoluted hose up out of an annular groove in the floor to expose the lower end of the hose.
Take care with those clamps they are hard to find if you need more, the regular hose clamp found in hardware/parts stores won't fit due to their worm drive size. The same goes for the inner hose, it's a metric size and a bugger to find if you tear it up. Abu Bin There Dun That!

Thanks Dennis, well give it a shot. Once off then how to put back on?

Well I suppose there may be several ways but our tried and proven method is to place the outer boot into the cab floor then fix the inner hose to the tank neck on the shop floor with the clamp making sure there is plenty of hose left to slide up onto the filler neck section. With a floor jack and wood under the tank jack it into place (we use a tranny jack). As the tank goes up into place guide the hose onto the filler section placing the clamp as you enter the hose. You will need to be firm with the convoluted section getting it held down 'n such but with a bit of practice you can nip up the clamp and loose install the tank fixing bolts. Once loose mounted adjust the hose to be a relaxed fit then snug everything up. Bingo!
Fill it with fuel and check for no leaks

G'Day Dennis,

How goes it?

I'm a little confused re this "convoluted boot" that you say is for decoration?
I've never seen anything on Pinny's other than that shown in the spare parts manual as per below.



Is the "convoluted boot" unique to Swiss Army Pinzgauers?

I don't know if it's unique to any particular series, but go to www.mcmaster.com and take a look at item 5298K73. It sorta kinda looks like that. It's a bellows-type arrangement that more-or-less seals the outside environment from the cab, an outer cover of sorts for the actual filler hose.

Hello Peter.
How's things down under mate?

Yes the Swiss set up has a convoluted boot slipped over the actual filler hose and located by I presume a wider hole in the cab floor and then attached at the top by a hose clamp (Jubilee clip???!!!)
Best regards
Dennis

G'Day Mike, Dennis ..... Hmmm. interesting how the Swiss have made subtle little modifications to all their vehicles.
I haven't heard of that one before....it's something new to add to the brain cells!

Things are going OK Dennis.
I haven't had much time to do any real 4WDriving lately as I'm trying to finish my MA Thesis, but once it's done I'II hopefully get a life back!

Peter, you are already amonst the Dr's of Pinzology, how much further can you go? Seriously, good luck with it.

Regards,

Andy
