If you're just in a tight spot and need to seal one banjo fitting you can
wrap the banjo stem with thin lead solder and crush it to make your seal.
The solder compresses into a solid seal under the pressure of tightening
the banjo bolt.
It does not require excessive torque to seal.
This is a temporary fix.
If I recall correctly the Britts tinned their banjo loops for proper
sealing on early model MGs, Triumphs and Healeys.
You can find a good supply of copper banjo washers at Harley shops.
Industrial hose suppliers will also have a good selection.
I've also cut copper washers from copper / aluminum plumbing pipe
.......... takes a fine tooth hacksaw and a steady hand but it resolves
emergencies.
