Tank Manufacturers

There are pretty much only two ASME LPG tank manufacturers for the North American market at this time: Sleegers Engineering in Canada and Manchester Tank in the USA. Both make excellent tanks and both have their own design features. Both Manchester and Sleegers make Annex G-certified tanks.

An important design difference between Sleegers and Manchester is the vapour box. Many installers find that running hoses inside the box is easier with Manchester's design.

Sleegers 16x36 cylindrical tank installed in an Impala. This tank meets CSA B51 Annex G and NFPA 58.

Manchester 16x34 cylindrical tank installed in an Impala. This fuel tank meets NFPA 58.

In Canada, all new propane conversions must use propane fuel tanks certified to meet Annex G. In Ontario, TSSA has issued an Annex G advisory: Propane Tanks For Highway Vehicles.

For their US customers, Sleegers sells tanks designed to US standards due to their slightly lower cost of construction. If you are in the USA, you may purchase and install Canadian tanks meeting Annex G in your conversion for an extra margin of safety because they meet or exceed the requirements of NFPA 58. The extra margin of safety is well worth the added cost.
