Hie guys,
I'm new here; I've got CNG kit installed in my hatchback Starlet. I carry model airplanes to the field in this car; now the problem is that I've started flying bigger and larger planes and I wanted to modify/change/replace the existing Fabre Cylinder with the one that fits in the cavity of the spare tyre; they're usually called Donut Shape Tanks; but after an hour of googling, all the sites that I landed to, were offering the donut shape tanks but for LPG's and not the CNG kit. Anyone here knows if such a cylinder exists for CNG kits that can fit inside the spare tyre cavity?
