MGB: Routing of washer line

1969 with electric windshield washer pump.

My question is where do I route the hose from the pump through the firewall? Can't seem to find any obvious opening.

Photo would be greatly appreciated.

Thanks in advance.

On my '70 it goes from the pump, in front of the heater box, and into the cockpit on the driver's side.

See attached photo that shows tube going behind fuse/relay mounting panel, and back out into engine compartment. It then goes in front of the heater box and then though a hole (about 1" diameter) in the firewall just right of the master cylinder.

Photo 2.

Never understood why that was routed to the left side. I guess its one of those RHD leftovers.

Thanks, that's exactly what I was after
