Frequently asked questions

What is the 850641 plain washer used for?

The 850641 plain washer is fitted at the fuel tank mounting points. Placed under the bolt head or nut, it spreads the clamping load across the mounting surface, which reduces the risk of the fastener pulling through and protects the tank strap or bracket material.

Which models use this fuel tank mounting washer?

This washer is used on the Defender (1987-2006) 110 and 130 wheelbase fuel tank pump and mountings, and on the Range Rover Classic (1986-1991) up to VIN HA610293. Check your fuel tank mounting setup against the fitment notes before ordering.

How many of these washers are needed?

The 850641 is sold individually, so order one per mounting point you're refreshing. Plain washers like this are typically renewed alongside the fixing bolts when dropping or refitting the fuel tank, so it's worth having one for each fastener location.
