I just installed a similar heater in my van the Russian ' Planar ' one , ordered directly from Russia . I had to drill into my tank mine is diesel though , so much lower risk of combustion , I don ' t know how you ' d go about drilling in to a gasoline tank . The Planar heater and I ' m assuming other brands come with an adaptor that you can tap straight into your tank . This thing airheaterplanar 8 dm 1224 . jpeg . I pulled up a section of my floor and drilled into it from above as that was easier for me than lowering my tank . <| sep |> 1 d 20 ugyghyt 44 Hey there !
