Another LPG conversion is on the cards in the near future, but on an Estate.

Having done a lot of research I have found that a 77L Full Toroidal, 4-hole tank (650diax270mm) will fit into the wheel well (with slight modification) if you build a false floor into the boot and raise it by about 75mm. Not a major problem, and can be done very tidily as can be seen in the pictures below (thanks to Cliffob ). But, it's not been as straightforward as expected because the gas tight box fouled on the wheel well... He has cured this with some a fair bit of work

So I'm now trying to work out the best course of action... I really need to get the biggest tank possible into the car, and 77L is it. That's fractionally smaller in capacity that the "tried and tested" 80L cylinder (obviously ) so the expected range is somewhere in the region of 270 miles around town, 320ish on a (spirited) cruise. Obviously, with the 'van on the back that will drop to around half that

Cliff has suggested that (if he were to order again) he would probably go for the 630mm dia tank, which is 72L. This should make the installation much more simple... The floor still needs raising, but it should drop into the wheel well with no problems whatsoever

I know we're talking about less than a Gallon of LPG in real terms but am struggling to get past the thought that we could get a bigger tank in

Any thoughts anyone? Particularly interested in H21's opinion on this subject

Was suspicious they wouldn't work... Bear with me and I'll upload to Flickr so I can link to them.

Can't really use a multivalve on a car with a full compliment of cylinders and horses Plus, multivalve would actually be even worse to try and get into the boot

Images weren't hosted by me, they were from an email from another member I'll upload them in a mo... They're on the way to Flickr as I type

Might try Dropbox in the future actually... May be easier, having seen it at work when I was at yours

I remain unconvinced that 4 hole is necessary, as long as you have a decent mutlivalve.  The MV6 is a mutlivalve, and (lag aside) suffers no issues - and the engines lives about 4.5k rpm (as Lazydocker knows why ).  Doesn't go lean either (occasional error in lpg ecu about injectors fully open).  Chrisgixer and Kevin Wood will confirm that, despite its 175k, it was every bit as equal to there cars at the time (Chris had a multivalve, Kevin has 4 hole).


I still, at absolute best, can only manage 290 from the Elite, that includes overfilling (tank needs another tweak), and being Miss Daisy through most of the tank.

Trouble is that a full toroidal tank with a M/V will actually be harder to fit due to where the M/V is positioned... 4-Hole is most practical from a fitting point of view Biggest dilemma is whether to go that fraction smaller to make it a little easier to drop in. I suppose we're talking less than 30 miles, even on a cruise, but just can't decide

Once we've had a try we'll know what's best when the Bonny Gold one appears

I wanted greater range, so considered 100l...


...then decided that I've had an 80l for the past year that I tend to fill every 175 miles anyway, so stick with easy install

Looks good, and the route I would want (With the smaller tank) should I ever go this route.

The estate i went to see only had a 47ltr tank , and the floor was still raised by a couple of inchs.
