2000 Miata 1.8L engine with standard components. 64000 miles.
So OEM Fuel damper had a moderate fuel leak. My original one has a rubber dangly bit that hangs downward. Not sure what the specific name for that piece is. And many of the after market replacements do not have it. What’s the difference? The oem ones have it and are twice as expensive.
Example:
Beck/Arnley Fuel injection pulsation damper has no rubber dangly bit.
While OEM part (BP4W-20-180) from Mazda has the same rubber bit.
Is the Beck going to perform different? Have higher risk of failure? Not work correctly?
Edit: Include Miata year and engine details.
