I was wondering if somebody out of the kindness of their heart knows the dimensions of a drop tank for an LX torana hatchback.
I need to know how deep they are, the depth and width.
All help appreciated.

same deal i want the dimensions for lh lx sedan...
surely someone would have one out of a car they could measure up.
i have a mig set up for welding alloy (my old mans buildin a 7 metre boat) so if we can get dimensions a may be able to knock a few up for some forummers
anyone know if hatch and sedan are the same??
i cant see the point of payin 500-1000 for a tank when alloy atm is only $7 a kilo!!

idss 57 I have a mate who needs a drop tank here in Canberra so if you do get around to making a couple he is probably very interested. As far as I know drop tanks for LH/LX sedans and hatches are the same. Only the UC is different.
Someone correct me if I am wrong!
From what I understand - and I am not a welder, the problem seems to be getting the bayonet holder for the sender unit welded in?? Something about not being able to weld steel to alloy??? Again I am not speaking with any authority here just something I have heard mentioned somewhere. I do know the sender unit from a standard tank works efficiently.

the drop tank for lh and lx sedans and hatches are the same. Just make sure if you buy one you get the units with the cut out for the spare wheel recess otherwise you have to mod the floor of your boot.
You dont really need measurements, just mock one up out of cheap mdf or cardboard as the two i have on my cars are built by different people and are different dimensions. A tip though is put some extra lines in the tank for fuel injection return, if you ever want to go down that path.

yeah i have already put the efi in so return point will be fitted. thats a good idea with the mdf i'll have a go at it when i get things on track. i really cant see the materials and welding cosumables costing more than $100-$150 a tank.. the only thing i'm unsure of is what herne said about the sender mount...what do the "bought" tanks have? i'll keep you all posted as i'm sure there are a few people who would be interested in them..

I have been looking out for a tank also but I'm not sure just yet if I am willing to pay 900 dollars brand new (with out a sender). Second hand they go anywhere between 300-700 depending on the condition.
I think if you're going to build one or a few, you should make a dummy tank and work off a model. That way there is less room for error. You've got things like the exhaust, spare wheel indentation, and also just generally, your desired look of it.
This link may help: OLD EBAY DROP TANK
I asked the fella for the dimensions and he told me:
side to side: 1070mm
front to rear: 550mm
height: 225mm
I'll be interested provided the quality is up to standard. If you make some progress please let us all know!

Theres no way that tank on ebay is only 90L. Its exactly the same as mine which is 120L.
There is that type (not sure on the brand) and there are the brown davis type. As far as I know they were the only mass produced drop tanks. I've seen hundreds of different drop tanks that all look very similer but you can pick the differences.
Usually they fill the space between the two chassis rails. Mine fits in with about 5-10mm either side and sits hard up against those brackets that hand down off the floor (rear end).
I noticed that 2WILD4U has a slightly different tank. His one is much narrower, perfect for someone going to full tubs (when you move the chassis rails in closer togther). There could be a good market for the because theres alot of drag cars getting around who can't run them. Just make sure you build in a swirl pot if your gonna market to drag guys.

All the alloy drop tanks I have seen have the bayonet fitting made of alloy too so in theory if one cut up a standard tank one could copy the bayonet fittings dimensions and then make them of alloy and weld them in place? Not sure how difficult it would be for someone on a lathe to turn one out!
Apparantly making the actual tank does not seem to be the problem.
From memory forum member 'Gloze 355' from Tasmania made some drop tanks but not the bayonet fitting. I could be wrong there but when I asked him about the fitting he said that was not included and I would need to find an aftermarket setup?
As is said I have a friend here in Canberra well known to some local forum members that really does need a drop tank but he is not willing to go past $400.00 for a complete s/h one either with straps or a bolt in model..
In the past 12 months I have purchased two s/h drop tanks, one cost me $350 and the other $400 - both were complete with straps, breathers, necks and sender units.

VDO make a range of top mounted sender units (sender unit only, no fuel pickup included) which bolt to a flat surface, and use a neoprene gasket. This could be used on a custom tank with just a round hole cut in the top, and five tapped bolt holes.
Depths range from 173mm, 222, 279, 322, 373mm. All have a resistance range about right, but would definitely need a 6.8 to 10 ohm inline resistor in the fuel gauge circuit, otherwise they'd overload the standard LH/LX fuel gauge.

If they are complete and look Ok then I have a friend here in Canberra who may want one. He definitely wants a tank I guess like so many of us he is also cash conscious.I currently have the drop tank out my SS, i am going to get a quote to have some made tomorrow, as soon as i know the cost I will post it up and see if anyone else is interested. The one I have is a bolt in type with a VDO fuel sender.
When the price comes through I will advise him of availability.

If you're going to make a couple for a reasonable price for forummers etc, then you may as well keep some for a less reasonable price suitable for strangers 
They are in high demand. If I had the equipment and expertise I know what I'd be making.

Thanks. I have the tasmania contact details.
I have a friend in metal fabrication so I thought I could get him to build one cheaper.

I got mine from Brown-Davis in Melbourne - bolt in, no straps. I was very happy with the service & quality of the tank. From memory they made the tanks for the race cars.

i would also be interested in the design of the internal baffles, considering making my own as i have the tools and materials handy. But i dont think the qualitity would be up to production standards
