[Mgs] Mounting bolt for s.u. fuel pump

[schultejim@msn.com]

Folks,
I am having trouble finding a bolt that will attach to the s.u. fuel pump which in turn will attach to a bracket on the MG. I have tried fine thread and course thread and none seem to go further then 1 full turn. It looks like fine to me but is it tapered?
