Air Filter - Double Layer
Likely- A226001410 — VIN prefix S04011
Also listed as part of the "Filter Kit - REPOWER" (P/N 90008) on the RePower Maintenance Kits page, confirming the same part number in the aftermarket repower-kit context.
Source: SRM-225 Trimmer - Parts Catalog / Lista de Piezas (Echo, Incorporated) — PDF page 10 of 31, "Intake / Admisión" table, row NO. 3: "3 A226001410 1 FILTER, AIR - DOUBLE LAYER".
Changed partway through production: The Intake diagram in this catalog is not split into serial sub-ranges (unlike Ignition/Starter/Fuel System/Control Handle), so it applies to the whole S04011001001-S04011999999 block covered by this catalog edition.
Fuel Pipe (main feed line), 3mm ID x 5mm OD x 90mm, black
Likely- V471001210 — VIN prefix S04011
Dimension code follows Echo convention ID x OD x Length in mm. A second, larger-diameter clear line (3mm ID x 6mm OD x 80mm, P/N 13201256030) is also present in both sub-ranges but not captured as its own row this batch. Bulk replacement stock is sold as P/N 90014 (3x5mm black, by the foot).

Changed partway through production: Listed identically (same P/N, same dimensions) in BOTH internal Fuel System sub-diagrams for this block (S04011001001-S04011081140 and S04011081141-S04011999999). Other fuel-line segments in the same diagrams (the return/vent lines) DO change part number between those two sub-ranges and are deliberately not reported here.
In-tank Fuel Filter
Likely- 13120507320 — VIN prefix S04011
The RePower Maintenance Kit filter listing on page 31 shows a slightly different filter part number, 13120507321 (ending in 1, not 0) - possibly an aftermarket-kit substitute. Only the OEM assembly-diagram number (13120507320) is reported here since it is what appears directly in the model-specific exploded diagrams.
Source: SRM-225 Trimmer - Parts Catalog / Lista de Piezas (Echo, Incorporated) — PDF pages 16 and 17 of 31, table row NO. 8 (page 16) / NO. 10 (page 17): "13120507320 1 +FILTER, FUEL" (identical, repeated verbatim under both serial sub-headings).
Changed partway through production: Same part number appears in BOTH internal Fuel System sub-diagrams for this block (item 8 in the first, item 10 in the second), so it is not split further within this catalog edition.
Purge/Primer Bulb - for RB-K93 carburetor
Likely- P005003110 — VIN prefix S04011
Do not use this part number if the unit has a GL-2 carburetor - see paired row.
Source: SRM-225 Trimmer - Parts Catalog / Lista de Piezas (Echo, Incorporated) — PDF page 7 of 31, "Carburetor - RB-K93" table, row NO. 32: "32 P005003110 1 +BULB, PURGE". - P006000040 — VIN prefix S04011

Spark Plug - BPM8Y (NGK), USA/49-state configuration
Likely- 15901019830 — VIN prefix S04011
US-market spark plug. A Canada-market alternate (BPMR8Y, P/N A425000000) is called out separately on the same diagram - see paired row below. Other SRM-225 serial blocks (Echo re-issues a numbered catalog per production run) were not checked this pass and should not be assumed to share this number.
Source: SRM-225 Trimmer - Parts Catalog / Lista de Piezas (Echo, Incorporated) — PDF pages 12 and 13 of 31, table row "NO. 7": "7 15901019830 1 SPARK PLUG - BPM8Y" (identical, repeated verbatim under both serial sub-headings). Corroborated on page 26 "Labels" diagram, item 1, listed under model labels SRM-225i / SRM-225 / SRM-225SB / SRM-225U. - A425000000 — VIN prefix S04011
Do not substitute for the US BPM8Y (15901019830) row - the source explicitly separates these by market/label, not interchangeably.
Source: SRM-225 Trimmer - Parts Catalog / Lista de Piezas (Echo, Incorporated) — PDF pages 12 and 13 of 31, table row "NO. 8": "8 A425000000 1 SPARK PLUG - BPMR8Y", diagram callout "8 CANADA" distinguishing it from item 7 (BPM8Y, non-Canada).
