Anyone fitted a 80l Dolium aux fuel tank?

[TuffRR]

Evening all

Wanting an auxiliary tank but don't want to compromise departure angle. I have a kaymar bar and as much as the likes of Brown Davis and LRA say their tanks don't reduce departure angle, this only compares to if the spare wheel was underneath which is pretty ordinary anyway. I don't need 100+ litres of fuel, but would like something extra as the 75l usable in the standard tank is frustratingly small.

Sooooo, Dolium make a 80l which i can only presume has a better departure angle than the 100+ litre tanks of the others but have not seen anything to confirm this. Would hate to go this route and still have same clearance as others but less range. Can anyone shed any light on how this compares to the other tanks out there.

Thanks.

I have checked out a D3 with the 80 litre Dolium aux tank with protector shield fitted. I'd be surprised if it had anymore ground clearance than a 105 litre Long Ranger tank, plus I priced them up recently and there wasn't that much difference in cost so why not just go for the 105 litre tank?

To me the fact that you can buy a protector shield for a Dolium tank kind of says something, I have a Long Ranger tank in my D1 and you can slide down steep rock faces on the tank and it doesn't get wrecked.

From memory the Long Ranger tank actually has a slightly better departure angle then a D3/4 has with a spare wheel fitted.

I have a 100 litre "Off Road Accessories" (WA manufacturer) tank under mine.

Departure angle / clearance is better than when spare wheel was mounted under there. The rear edge of the tank is only about an inch lower than the bottom of the (original) bumper. I have seen other tanks which sit considerably lower than this.

Yep I have a Long Ranger 105lt tank in my D3 and departure angle is better than with the wheel in place and couldn't really get much better as other things are going to get In the way before the tank. Do be aware though that with the wheel out the back and the tank underneath full it does significantly change the handling characteristics of the vehicle and not for the better. It's nice to have the extra range, but I have to say I like driving the vehicle much more when the long range tanks empties out.

Mines a Brown Davis 120ltr ( probably more like 110 now!)
It has had a bit of a beating:

Looks like I need to tweak that silly position drain plug.
I have hit the tank so many times and it has plenty of dents in it but haven't ripped the plug or bottom out as yet.
I'm sure I would of damaged a rim or tyre if they were under there!

Hi all,

Digging up this latest (?) aux tank thread, I've read through quite a few threads on these tanks and one of the main differences apart from clearance/departure angle considerations seems to be whether fuel is gravity fed or pumped from aux to main tank.

So, based on my understanding, my summary is:
Pros of gravity fed
- no pump so simpler, more reliable
- no pump switch (or extra gauge?) needed so no change in cabin i.e. adding switch/ gauge in dash

Cons
- less control managing fuel between tanks
- no visibility of actual (total) fuel level

and for pumped options, the opposite of above.

Interested in people's opinions on this aspect of these tanks (and anything else worth considering of course.. )

Thanks,
David

I have the same as BMKal and got it from Opposite Lock. Fits perfectly but does blow back a little bit when filling up just as it get full.

With pumped tank if oe tank gets holed you do not lose all your fuel!

Same as BMKal....works a treat and hardly any blow back at all.

My tank was fitted by opposite lock several years ago to my 2005 D3. Enough rough stuff to give me confidence the departure angle is not compromised nor has the tank taken much of a hiding. I have the dolium roof rack so the tank might be it as well. It is too dirty to see today and my memory is short
It is gravity fed and no problem with finding out I only have one full tank left myself given a 600km + range on one.
I did see once some fuel go back from main tank to the Aux when on a very step very long climb. It has a one way valve but it clearly did not seal totaly but it was only a interesting note not a issue for me.

I like the gravity fed due to being in favour of 'Keep it Simple' myself who is often the 'Silly' enough part of that saying.
