yeah i recon its a bit dodgy and yes the only real part ya not spose to do is the service line but i know ppl that do it and get away with it but u MUST use seamless copper and here it dont have to be a kit i just collect parts here and there for the jobs i do in the U.S u could go straight to impco for the bits thay make good gear at prety good prices and are very reliable easy 90% of cars here use impco the epa thing sounds dodgy too cause lpg is much better for the enviroment its got me buggerd
