Hello
I have a few questions about a Vialle D-Type lpg system I have aquired
from an old Fairmont approx 1987-88 vintage 3.9 ltr.
I would like to know if this can be fitted to my Isuzu ute (Holden
Rodeo) with a 2.6 ltr 4ZE1 engine?
Does anyone have any literature for the vaporizer (Vialle D-Type)
giving details of it's parts i.e manuals or schematics?
I'm new to this LPG thing and no one I,ve spoken to so far knows
much or you must know thier secret password and handshake to be able
to get any info.
any help or advice would be greatly appreciated

The problem, atleast in NSW, is that all installs have to be certified by a
liscenced installer, and an aluminium plate is attached to the car with the
installer's credentials. Plus, fines are high for any unauthorised work. In
theory, you aren't even supposed to tune it yourself,...One mechanic told me
if someone brings a "backyard" job to him to fix or do a rego insp on, he
charges them as if it was a new install.
So best of luck.

It can.

Just about any lpg equipment can be fitted to any engine, with the only
"gotcha" being how keen you are to put effort in to make it work.

Excluding modern direct gas injection systems, there's basically two main
components used under the bonnet of every lpg system, being the converter
and the Mixer, and of these there is a simple & complex version of each. The
difference between them is largely which one allows you to make the tuning
adjustments. Complex converters have the adjustment controls built into
them, and are used with a simple mixer (which most times is little more than
a large "jet" which allows the gas to be delivered into the engine), whereas
simple converters have no adjustment and work in conjunction with a complex
mixer which incorporates all the adjustment controls.

As to which system is the better of the two you're likely to get many people
favoring either. Personally I much prefer the simple converter/complex mixer
as being the better system for tunability and performance, but if your
system works and you're happy with it then it really doesn't matter.

As far as Vialle is concerned, I'm pretty sure they've only ever made
complex converters.

I'm not familiar with your Rodeo's engine, but if it's a carburetted unit
you'll need a simple mixer that goes over the top of the carb (usually under
but sometimes inside the air cleaner) that connects to the converter and
introduces gas into the engine. If it's an EFI engine, then they normally
run a simple ring type mixer that gets plumbed into the air intake tubing
between the air filter and throttle body.

You said you've got the "system", which I presume includes a mixer of some
kind, so the only difficulty you'll have (apart from fitting the equipment
itself) is finding a mixer that will fit your particular application if the
one you have isn't suitable.

I don't know where you are, but these guys have a range of different mixers
at good prices (as well as a host of other lpg spares & equipment) if you
need one:

They're also pretty helpful, and don't mind helping out with advice if you
need it.

Thanks guys thats great
I neglected to mention that I,m from Rotorua NZ and proffessionals
are few and far between.
The Vialle converter or vapouriser has 3 adjustment screws so is a
complex one as you mentioned Noddy and the mixer is just a hooded
cover over the top of the carby with a pipe at the opening of the hood
to introduce gas vapour to the engine.
This hood of course won't fit my ute so was wondering if it is
possible to make my own?
I'm keen to do this install myself as a liscenced local mechanic
will certify my install when it's done but he's not very forthcoming
with details.

Cheers
Craig (Kegman)

I'd take it on a holiday to Australia, Victoria being a great place to
get it fitted. Then you may even be able to get the $2000 rebate
theyre offering, if its legal of course.
