Thread: Consolidating my Disco 2 research

I have no idea how'd you'd fit them without a cradle,,,

make sure you get maximum seperation at the fuel fillers,, can be very tricky to get the fuel cap off

my pulp tank has a tendancy to leak when full,, not much, but enough to drip,, mind you a full pulp tank would be 6 months worth of fuel

I've been trying for a while to get the LPG conversion without losing boot space. Here in WA it's pretty hard here to find a fitter interested in giving me anything other than a boot manifold or cylinder. I have however, managed to talk some into it on the condition that I handle the petrol tank swap and give the car to them with a nice big space ready for the LPG tank(s)


Every petrol tank supplier I tried in WA has turned me away (including all the LR / RR specialists) but it seems that Brown Davis (55L -$680) and Ritter (45L - $490) can still supply their tanks for the rear right quarter. So I'll probably go with one of these and pay the postage.

Ritter also have a cradle ($275) for 2 H66 tanks and a tow bar adjustment ($99) to allow both H66 cylinders to fit.

I know a few guys on here have these setups (that's how I found them), so I was wondering if I could get any pictures or advice about them?

Do you suggest I get the cradle and towbar adjustment or are they easy enough to sort out myself?

Do the Brown Davis or Ritter petrol tank kits come with everything needed for an easy install? I couldn't get much info or pictures from them.

The cradle and towbar fitting from ritter sound like they'll make life a lot easier. Do you guys suggest getting them?

Are there other places to get the towbar and cradle?

The brown davis tank I believe is supplied as a kit and should be an easy fitment. I haven't installed one but I told a guy to fit one himself and let me just do the gas. It looked a good fit.

The cradle is not a hard thing to build if you know what it should look like, but $275 is probably cheaper. It takes quite a while.






The towbar mod involves bending the stays that connect the towbar to the side rails. They come off without the whole bar and are fairly easy to modify. Whether they pass a picky engineer when modded is a question, but I was happy to do it.

Sorry no pics of the bar mod and B-D petrol tank.

The AMR dual filler kit for LPG in the petrol hatch is neat and comes with a compact petrol cap that slides under the gas connector. Easily fitted.

Thanks for that info guys.

Sounds like the cradle is worth buying. Years ago I would've said "That looks easy. I can make that and save some money." but I suspect it would take a whole weekend in the shed before it was just right. Longer because I always try to make things out of what I already have.

Did you guys make your own (as pictured) or buy the Ritter one?

I might leave the tow bar adjustment since it sounds simple enough to tinker with the standard frame. In some of the pictures it doesn't even look like you've bent it at all.

Ritter also offered a dual filler assembly for $75. Sounds like it might be worthwhile.


All seems very manageable now thanks.

The only pity is that the BD tank is 10L bigger than Ritter's. So if I bought their tank separately it'd cost me about $300 more (including the postage).

Brackets off vehicle, sledge hammer (or a hydraulic press for the fussy ones, yes you *****), angle grinder and a bit of adjustment at the chassis end mounting. They need to be off to remove the petrol tank and fit the cradle anyway.

Well for all my high hopes, none of the fitters I've contacted want to do a dual tank (twin 310 x 660) even if I have the cradle ready for them. Looks like it'll cost an extra $1000 over a 50L toroidal.

Even though I'd prefer the extra 18L, I don't think I can justify the price.

I may still try to get a slightly bigger single-cylinder in. A 432 x 625 may fit and give 61L.

Good grief, tell them to stop being ninnies and get the twins fitted. The trick with the twin tanks is to plumb and wire them with flexible hoses before they are lifted into position. The "T" connector valve on the engine supply hose and the filler get connected after the assembly is lifted into place. The tanks are left loose in the cradle and as they are raised with a trolley jack/trans hoist they are rotated into their final position. Dead easy really.

BTW the twin tanks pop up on ebay regularly as they have been in fashion for decades on the D1 and RRC. Try some Landy wreckers too. Retesting isn't that dear. Just check that anything you buy is returnable if it fails its test.

Don't go for a single tank as the ground clearance will suffer badly.

Yeah I thought it would be easy too.

What's a fair price for an installation like this?

I'm being offered around $4400 to install a single toroidal tank. This is assuming that I remove the standard PULP tank and fit the small one myself before giving them the car. So I have to add the price of the PULP tank ($590-780)

$5500 if I want the twin tanks installed.

I feel like these prices are a bit high but I can't seem to find any cheaper.

Worse still, none of them have done many (if any) Discos.

The only problem with a toroidal is your chassis rails are 630mm apart, so a common 650 won't fit unless they use a BIG hammer. The 600 x 240 from Blue LPG is 50WC or 40 usable. Twin H66's are really the only sensible solution so I suggest you keep trying to find a sane gas fitter over your way. And keep looking for used tanks. If you find a set with cradle it should be possible to mod the cradle to fit the D2, it's not that different to a D1 in the petrol tank area.
