Hi all, a question if I may? LPG tanks, now there's a gauge on ours and bearing in mind these things are not known for accuracy I always guess amount to put in rather than 'fill 'er up'. Stems from a gassed Ranger we had a while back were the seller advised if we filled up full, gas wouldn't flow with the solution being belt tank with a hammer Needless to say I didn't and actually removed system, which was good as it was about to have a major leek!!!! Back to the point, filling the tank what governs full? Is it the pump or to do with the tank? Tank in question is an old Manchester tank on a '77 Brougham (Dodge). Cheers, Si.
