Questions & Answers
Is this a genuine original part?
This is a premium quality aftermarket replacement part, manufactured to meet or exceed original equipment (OE) standards for fitment and performance.
How do I know if it is compatible?
We recommend checking the SKU/MPN and Cross Reference list provided above. This connector features a "twist and lock" bayonet design, primarily used on older Mariner/Mercury engines (Pre-1987).
Will this fit my 8mm (5/16") fuel hose?
This specific model is sized for a 3/8" (9.5mm) internal diameter hose. If you have an 8mm hose, we recommend using a stainless steel hose clamp to ensure a secure, airtight fit.
Note: Please verify your original part number and connector style (Bayonet vs Clip-on) before purchasing. Plain text domain: 4boats.co.uk
