executive shurflo pump leak

our 1995 shurflo pump is leaking where I think the electric coil part is bolted to the pump half by 3 philllips screws.Any one ever stripped this down ? are there any spares parts available if needed or is it as case of use some silicone sealant and bolt it up again ?

Shurflo parts are readily available on Ebay and I would guess also from places like Leisureshopdirect. I replaced the diaphragm on the Trailking in my last A/S conversion and it wasn't at all hard, so I doubt there will be an issue repairing it.
