Frequently asked questions

What is the union nut used for?

The union nut is a fuel pipe fitting that clamps a fuel line onto its adaptor using a compression olive. On the 2.6 litre six cylinder Series models it typically secures the pipe from the carburettor to the fuel filter, sealing the joint against fuel leaks.

How many union nuts are needed for the fuel pipe?

Union nuts are typically fitted one per pipe end, so a carburettor to filter line usually needs a nut at each connection. Fit a fresh olive with the nut for a reliable seal. Check both ends of your fuel pipe run before ordering.

Are there alternative part numbers for this union nut?

This union nut cross-references to 572535 and 542846 in the parts catalogue. It suits the 2.6 litre petrol Series fuel pipe union. Confirm the pipe diameter and thread against your original fitting before ordering, since fuel union sizes vary across engines.

Can the union nut and olive be reused?

The union nut can usually be reused if the threads are clean and undamaged, but the compression olive should be replaced every time the joint is opened. A used olive rarely reseals, which risks a fuel leak. Fit a new olive when refitting the nut.
