Title: Well, I've seen some ropey LPG installs in my time..

.. but a professionally certified one with the tank fitted upside down... That's a first.  :-X

It's positively advantageous if you've got an ice cream van. ;D

As long as the multivalve is in upside down too it's ok ;) ;)

Which, IIRC, was the same advice I gave Nursey when I told him the tank was upside down ;D ;D

I should clarify that the multivalve is upside down, and the gas tight housing, the works.

In fact, the writing on the tank is the right way up IIRC, but that's about as far as it goes. ;D

Ahh :-X :-X :-X :-X

I'm guessing the visit to you was because it had a ridiculously short range then :D :D :D

Trouble is, it'll be pretty hard to just drain the tank (with the pickup in the air) to make it easy (and safe!) to just rotate the valve ::)

I suppose he could get it into the workshop with an extractor and let it go :-\

Ah, phew, as my (certified) tank is upside down on the MV6, to put the multivalve the right side of the car. The valve is the right way up though...

It seems to work until the car has been running a while, at which point I reckon the tank gets very cold and the pickup fails completely under load as there is little energy left around the tank to enable the gas to boil.

I will run this tank down driving small trips until it gets empty and then whip off the multivalve.

Easy enough to do...  :y once you can't drive it on gas, leave it idling on gas (you'll probably have to keep switching it) to get all you can out! Then do it in a well ventilated area with proper precautions ;)

I think the range would be fine if you stopped every hour or so to let the slush puppy in the boot melt. ;D

I was quite surprised. Runs perfectly OK (bar a couple of unrelated niggles that we need to sort). After a bit of driving flat out acceleration will cause it to drop to petrol due to low vapour pressure. Not the normal gradual reduction in pressure as revs build from a poor liquid flow, though. It just disappears.

Gets worse the longer it's driven.

First fill was really slow for the first 20L (90L tank) then went much quicker to the top.

Gauge reads full when empty and empty when full.

The part of the tank containing the liquid gets cold.

The airtight box has its lowest duct outlet about half way up.

All the signs are there, and a couple we pondered at Newent, I know, but we talked each other into it being OK. ;D

I think a bit of gentle commuting will empty the tank then we can get the multivalve out and check.

What amazes me is that a UKLPG professional put a certificate on it. ;D

I know we were both undecided but the plate on the tank was enough to let us convince ourselves it was right ::)

Tbh, I doubt the inspection was that intensive if Teilo sent him up there ;)

I must admit I went off the writing on the tank when installing it  :-[ ;D

Kev and I both looked long and hard at the multivalve but still managed to get it wrong ::)

Mmm, my gauge on the tank also reads the wrong way round.Got me wondering now....... :-\

Is the tank cold (noticeably colder than ambient, especially below the fluid level) after a drive? That's the acid test.

I shall have to check on that. :y

I don't think you have the same problem Albs... I've done calibration runs in that car and would expect to have had issues with LPG pressure  :-X Plus, the range is about right for that size tank with 2 different people driving ;)

No harm in looking though

Yeh the range seems about right actually.200 miles from 60l tank, on a good day.Probably worrying over nothing.
Which reminds me,I havent looked at the filter yet. :-[

I'm quite confident that Guffer will get decent range out of his, but I would have thought any car with this issue would be dropping back to petrol at times (and suffering a lot of condensation or even ice on the tank).

Post by: albitz on 05 October 2011, 13:36:40
Mineused to drop back to petrol, butthat was due to the coolant syatem being plumbed wrong.Pretty sure the tank doesnt ice up.
The whole front end really needs a good tidy up/ reinstall though.Its on my to do list - probably next spring at the present rate of going. ::)

that's nothing, I've seen an LPG ECU secured to the underneath of the wheel-arch (i.e. wheel-side) using no-more-nails before.
