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 in marine environments.
How do I know if it is compatible?
We recommend checking your existing fuel connector. This kit fits late-model Mercury and Mariner outboards (typically 1998 onwards) that utilize the clip-on style quick disconnect fitting.
Can I use this with high ethanol (E10) fuel?
Yes, the hose and primer bulb are constructed from alcohol-resistant CPE rubber, specifically designed to withstand the corrosive effects of ethanol-blended fuels.
Note: 4boats.co.uk recommends verifying your original part number against the references above before purchasing to ensure perfect fitment.
