Could a 76L donut LPG tank, fit in the spare wheel well of an Omega Saloon?

Or is the max 55L? 

[chrisgixer]

If only no could remember the sizes.

I tried the next size up to what I had, and it wouldn't quite drop in without catching the side if the boot opening

I reckoned it could be made to fit by subtle adjustment of the wheel well and floor. But the reality of these things is it will take bloody ages to sort, may well affect the metal work of the car, and quite possibly not come out again, ever.

It takes a few attempts to get the plumbing to sit right behind the tank. It's fiddly on a single hole, and space is limited behind there once the air tight hose is fitted.

It will be a ball ache.

Edited to add... tank is a four hole 650x270...

There are two issues to consider...

1. Width of the spare tyre, 195?, versus the width of the tank, 270.  Physically it won't drop in.

2. Tank is designed to be mounted flat, not on its side.

If you were to mount it in the rear corner of the boot, it would take up a little more height than a full size spare, so should allow use of the folding rear seats. Would suggest right hand side to keep the plumbing off the exhaust though

Booo. 

That's that then 

Shame, as Al's kit would have done the job perfectly.

I need all of the boot in the 3.2, so mounting it in the boot anywhere is an issue 

[tunnie]

Also 55L tank is just not enough, I would need to do a run to Wales & back on a tank of gas, with some spare, 55L just does not give that range.

[chrisgixer]

I agree yes. 55l also means it's less economical, due to running out if gas quicker, more often and messing about looking for LPG stations. Especially on holiday when your off your own patch.

... I suppose it wouldn't take much to cut cut the boot floor and make the well wider. But the shape of the base of the wheel well also means it sits higher. No real biggy, just means the carpet wheel cover won't fit and the tank may have to be lifted out to get at the light cluster. Although changing a bulb might be easier if you have gadget hands.

Also last i looked they only do single hole uprights. They aren't the most reliable.

Where's the spare wheel going to live then?

[05omegav6]

Install one of theses or similar...

And lose the petrol tank completely

Having seen quite a few V6 installs, it's clear that a 3.2 would really need a 4 hole tank, even for me.

In the garage

Not sure I follow 

[05omegav6]

If you pre heat the coolant, you don't need petrol to start the car from cold

If you find it close to the line, you can easily get a custom petrol tank made to fit next to the donut under the boot floor as a justincase back up...

[tunnie]

Ah I see, good suggestion, but always need to have petrol tank there. As you never know

There are some 12 Volt ones around but they do hammer the battery, so probably some sort of second battery set up required.

Out of interest I was running a 1.4 Tigra on LPG only for about 3 months last winter without any issues, just needed a minuet or two before driving off other wise the ECU would moan.

Left mine in the boot unless I needed the space. Then it was either in behind the front seats or as Tunnie says, left in the garage and risk it
