Mk2 escort fuel pump gasket

[beu_79]

Evening all,

been having issues with fuel pump on my 1300 Ghia, so I swapped it with a new one. Old one came off with one gasket and no spacer, the new one came with 2 gaskets. As there was only one gasket on when I took it off, I only put one back on but now it’s leaking oil. 
 

does anyone know what the setup should be, should I get a spacer with the gaskets either side, or do I just double up on gaskets?
 

as always many thanks if you can help.
