LPG is great stuff, but like gearbox oil, it stinks!
if you dont need any form of a boot, you should be doing it. the fuel has a longer shelf life and doesnt have the contaiminents/additives of petrol to carbon up your engine.
if you have ever pulled down a lpg forklift engine, they are pritty clean inside compared to a diesel, they do so many more hours too.
recommend you get a decent
ECU to make use of it though.
