Never run an engine without a filter — even briefly causes abrasive damage. Pre-fill fuel filters with clean fuel before fitting to reduce prime time. Replace O-rings on filter housings every second service. Record change dates on filter housing.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
