Mercury / Mariner Fuel Pump Diaphram Kit (55278A5)

The product you wish to order is a second-hand part. These are useful parts that have been carefully removed from end-of-life engines by our mechanics and have been approved for sale.

Please note: these are not new parts. We show the condition of the product as clearly as possible using photos. If there are multiple items in stock, the image may differ from the part actually shipped. Functionality is always our top priority. If you would prefer a new or original part, please choose the original/new variant, if available.

Second-hand parts cannot be returned. The reason for this is that we cannot verify whether a returned part is still in the same condition as when it was dispatched. With electronic parts in particular, there is a risk that a fully functional part may be exchanged for a faulty one. By agreeing to these terms and conditions, you confirm that you are aware of this.

Please take care with electronic parts relating to your engine’s ignition system: are you certain that this is the part causing the fault? We regularly see parts being ordered in the hope that this will resolve the problem. If you are in any doubt, please consult a specialist.
