LPG tank on a syncro

Postby crazydiamond » 02 Nov 2017, 17:26

Now ive got an internal cylinder tank on my syncro. Holds about 55 litres. If I wanted more LPG capacity, could I fit a torroidal tank behind the bash plate under the front? and still have a bash plate fitted, then get the two tanks connected. I would get the installation done by a proper gas lpg fitter not diy!!

When I spoke to someone about it he was going to connect the leisure tank and main tank to one filler. So why not? Give them a call and ask. Let us know

My toroidal tank sits in the wheel carrier nicely, you have to unhook the two bars that hold the tyre down from the bumper. Think it's 55L

How many miles do you get from your tank?

There's no space for a tank under the bash plate.

seen a few installed in the bash plate, it's real tight for space, I think 48 litre tank so that's 38 litres of gas so maybe 150 miles extra range, the problem with dual tank systems is if they are different tanks then they fill at different rates and when the smaller one is full it feeds back to the pump and the pump stops filling, you need to be able to isolate each tank, fill the big one full then the small one; I have a small leisure tank on my filler system and I had to isolate it in order to fill the fuel tank properly, but that means going on my knees to reach under the van to the isolator on the petrol station forecourt, fine in summer a pain in the rain and snow :roll:
also anything fitted in the bash plate void limits access to the bottom of the gearstick and the steering rack, having to decommission the gas system and remove the tank to do vehicle maintenance isn't a good set up and those I have seen tend to have odd bits of bracketry welded or bolted to the chassis to support the tank which tend to be in the way of other things or manual access to other things
Do one day a weeks contract work and put some petrol in it :ok

Aidan makes a good point on access. I went to Campershack near Grantham and Andrew used a spare wheel carrier to mount it and I think it was designed in a way to make it easier to remove for work.

I opted for two underslung tanks on my syncro westy, One up front, to replace spare wheel and one underneath the sliding door. I have noticed that when I fill up, it starts pushing back gas when I move onto my second tank, it will refill, but it takes longer. I can carry between 75l -81l of gas and I get roughly 300 miles. I am lucky to have two LPG fill up stations very close that offer LPG at 50p. I tend to do 300-350 miles a week commuting on motorways to wholesalers and fish mongers etc. For me it worked out cheaper to LPG and not loose any space. But if I was just using it as toy vehicle with the occasional holiday, I might reconsider the option.With combined fuels, I have a range of over 500miles. Finding a fill up station in more remote areas can be a pain, but I tend to use petrol at that point, rather than let LPG filling dictate my schedule.

This isn't a great idea.
The 80% fill shutoff valves vary in efficacy, so when filling up for road fuel, if you haven't used any leisure gas since the last fill then the pump could overcome the valve and force a little extra LPG into the leisure tank. Over several fills this is cumulative, and can possibly overfill the tank to a dangerous level. In this scenario the vapour takeoff could pick up liquid, possibly damaging the regulator, or worse. It is then possible to have liquid propane delivered to the hob rings or fridge, and you don't want that!
Of course, none of this applies to twin tank road fuel systems, as they'll fill together and empty together, using liquid takeoff valves.

And yes, a toroidal will go above the bash plate, but it's a much cleaner install if you fit a slightly smaller tank than the usual 2WD option, something like a 600x190, giving 43L air (34.4L @80%), so maybe an additional 150 miles range.

I do worry about the spare wheel? Where would that go? Don’t like the look when they are out side as only a 2wd and no space inside. Dilemmas!!!!
