Fuel Tank & Fuel Line Exploded Parts Diagram - Refs 972, 972B, 957A/B, 187 Series

This document is an exploded parts diagram showing fuel tank assemblies and related hardware, identified only by numeric callout reference numbers with no accompanying text legend. Two main boxed views are shown: reference 972 (a fuel tank with filler neck, fuel cap 957A, and a round screened cover/blower housing style part 930) and reference 972B (an alternate fuel tank design with cap 957B). Additional standalone callouts show two fuel cap variants (957A and 957B), a fastener kit or bolt set (1059), a bolt (190), and a washer (670). Along the bottom are four detail boxes showing fuel line and clamp configurations: 187 with clamp 601, 187A with clamp 601, 187B with clamps 601 and part 240 (an in-line component, likely a filter or fitting), and 187C with clamp 601A. A reader can use this diagram to identify part reference numbers for the fuel tank, fuel caps, fuel lines, and clamps when ordering replacements, though the actual manufacturer part numbers would need to be cross-referenced from an accompanying parts list not included in this scan. The drawing style and reference numbering are typical of a small engine illustrated parts list.
