Review on High-Performance Fuel Pump Kit for 🚀 Mercury/Mariner Outboard 21-857005A1 - 18-7817 Diaphram Washer Kit by Calvin Booker

Don't buy this. It worked for about 5 minutes and it was great. Then he stopped working a mile upriver. The rubber membranes stretched and wore out almost immediately. The springs were also the wrong size. Whoever did that didn't know what they were doing and didn't care that people's boats actually worked. I should have trusted the terrible reviews before buying it but thought I'd give it a try. Don't buy this! Spend the extra cash on parts that actually work.
