Big LPG tanks 200L +

[Hardchina]

I'm seriously thinking of going large and fitting a 200+ litre lpg tank, any body else gone the big tank option? Any idea of $$ for the tank?

I reckon 200l should be enough for some decent trips.

Thoughts....

What in?
I always recommend twin tanks, 100L each. Lighter, easily available, no engineers report needed, you can remove 1 and retain the other if you get sick of it.:)

Sorry mate, 85 county - thinking of going in the footwell for the rear seats.

I've got a 50l tank under the sill but that looks like the biggest that will fit down there.

Do I need an engineers cert for a big single tank :( ?

Would 2 x 100l tanks fit between the doors of a county lengthwise?

The biggest popular tank you can fit without engineering is the APA model A140 tank, 1400mm long 375mm diameter, 114 litres LPG capacity. You could get 2 across the wheel boxes in a county, window to window. Just so happens I have a 85 defender in my workshop here I can measure. Any tank over 150L water cap. (120 LPG) needs engineering and is awful heavy.
You could drop 2 APA model D90 tanks in the well, 900 long, 432 diameter, 92L of LPG each. Work out your dimensions and I can suss the APA catalogue hanging on my wall.:)

A140 tanks weigh 46kg each plus 5kg brackets plus 57kg of LPG. D90 tanks weigh 45kg each plus 8kg brackets plus 46kg of LPG. The biggest stainless steel tanks ever made were 104L water cap, 82 LPG, 360 dia by 1100mm long. Rare but findable and 1/2 the weight of mild steel tanks. Longways you could fit two APA D100 tanks with the control boxes over the wheel boxes, 102 litres LPG each, 1000mm long 432 dia, 50kg each plus brackets 8kg plus 51kg LPG

Ive got 1400mm x 400mm to work with. I,m talking of the middle seat well, not the rear bench seats ( i need that area ) all the middle seat well is good for is storing smelly old mcdonalds wrappers and empty cans :p

Also - how large a tank would you need so it would boil off enough vapour to supply the engine, without needing a converter? It would be cool to get rid of it!

Cheers

In the early 1970's I owned a Bedford KMR-XT5 with Detroit 6V53 engine. I participated in trials by Repco with LPG assisted Diesel engined vehicles. The gas tank was 600 lbs. capacity. It was hung off the chassis rails on J-brackets like any truck distillate tank. Are these still available?

Aah across the doors, now I get it. Apart from the A140 most tanks are 1100mm or 1500mm long, nothing in between.

If you mean getting rid of the water heated converter, forget it unless you are enhancing a diesel. The LPG mixture would change as you evaporate the propane, then the butane remaining would stop supplying pressure at 0 degrees C. No go in frosty conditions!

The biggest LPG tank on my list is the APA E160, 1600 long, 508mm dia, 298 water cap, 238 litres LPG. I have one similar banging around my yard, no-one installs stuff like that now.

600 lbs = 600L :eek:

you'd want to use a filler with the hold in catch thing for that !

It probably means 600lb water capacity, which is 218 litres of LPG. The tank I have was off an old Bedford and I can't see anything twice the size fitting on one of them.:o

As far as I can recall, its nominal capacity was 600 lbs. of LPG. It was larger than the round 100 gallon distillate tanks used on most line haul prime movers at that time. The KMR-XT5 was a single drive prime mover with 6V53 Detroit, RT610 Road Ranger, and an Eaton rear axle. To fit the gas bottle, the fuel tank on that side had to be taken off.

That is big.:)

It had to be big as there were few servos outside the major cities then that sold bulk gas.

I have had little to do with LPG other than in camping size cylinders and appliances since then. I do recall that bottles then were sized by nominal capacity in lbs. weight. The normal domestic cylinder was 100lbs.

At that time there was a bonnetted Oshkosh with a big 6 cylinder gas engine, I think it was a Waukesha, that ran Sesame Street, and it carried two of the 600 lb. bottles. I spoke to the owner once at Repco and he told me he had seen these engines used as well head and pipeline pump engines in the USA running on gas straight from the well. He was impressed with the fuel consumption figures and got an Oshkosh custom built on an order from the Australian distributor. He did say that fuel cost per mile was well below the cost of a diesel engine of similar output. Never saw him again and never saw another truck in this configuration so I don't know what the subsequent history was.

I have an APA 1400 across my Chassis under the tray, as well as 2x45 litres in place of the fuel tank. Works well enough.
Forget vapour withdrawal.
Imagine the fuel line size:eek:. It would'nt get certification, therefore un insurable & no rebate too.
