any other place other than the rear quarter is now not permitted now under new guide lines because plastic bumpers are to weak and fitting to the towbar is far from sucure
Well, I've had 1.8 tons of trailer hanging off my towbar and it didn't go anywhere. I'd say that's secure enough for an LPG filler.
any LPG car will be subject to testing and if found not to be up to standard then your insurance company will not cover you
So, someone's going to knock on the door of every LPG car owner and demand that it's tested? :-/
and part of this reason for this test is to try and stop the DIY kits being sold and fitted.
This has always been the dream of the LPGA / UKLPG. They are a trade association and, as such, exist to generate work for their members over and above anything else. If their members were policed a bit better and not such total cowboys they might have made more inroads in that respect.
UKLPG can dream up whatever rules they like. Until there is either a legal obligation to use only their members for LPG work or 100% commitment from the insurance industry to require vehicles to be converted by their members, DIY LPG will carry on unaffected.
Has any one come across this yet because i was thinking about buying a kit and fitting it myself, also he said about single hole tanks are c**p and to go for a 4 hole and to try and stay away from polish systems and go for a danish made system :-/ :-/
Makes no odds where the system is made as long as it suits the car. I have a Polish setup on mine and can't fault it. Choice between 4 hole and single hole is down to budget and power output. Nothing wrong with a single hole tank, certainly below 200 BHP there is little advantage in going 4 hole IMHO.
This sounds like typical scaremongering from an LPGA "professional" - the type who drills intake manifolds in-situ, most likely.

"done properly" very rarely applies to a commercial LPG fitter. You could do a better, safer job yourself in pretty much all circumstances.
Agreed.

Thinking about it, if you were going to change from petrol to diesel, you wouldn't keep the petrol injection system, blank off the injectors and then add a piggy-back device to run the diesel injection system, would you ? But that's pretty much how an LPG conversion works.
In an ideal world you are correct but most people wouldn't want to change to LPG but have dual fuel capability due to the less than widespread availability of LPG.
Given that you've got to retain the capability to run on petrol and the petrol ECU is quite tightly integrated with other systems on the car (automatic gearbox, ABS/TC, etc.), and this varies between models of car the most standard interface where you can connect the LPG system is at the fuel injector output of the petrol ECU.
This is a compromise, of course. You would design the engine itself differently for LPG and the need to start on petrol is also a symptom of piggy backing from the petrol ECU.
