This morning we decided to try and find an Acogas place we had read about where other travelers had purchased an adapter that allowed US fixed propane tanks to be filled at gas station GPL pumps (location details in the camping section below). This proved to be a challenging driving experience as it took us on some of Lima's busiest streets at rush hour. Also took us through some of the up market shopping areas. But it was successful; we got the fitting and a couple of hours later at a gas station filled our fixed tank with no trouble.
