Mike -

 

It sounds like you will not be installing the header tank in your 360.  I do have a header tank, and I have mounted my hydraulic pump between the copilot instrument panel and the header tank.  There is actually room for that, but not much room for the other stuff you might want to mount there.

 

Anyway, that's not your situation.  It sounds like you're considering mounting the pump on the vehicle centerline, affixing it to the nose gear tunnel.  Might I suggest doing what Marv did, which is to intall it to the firewall towards the side of the fuselage (not on centerline)?  Marv cut out a corner of the header tank to make a small compartment for the pump.  He then made an access panel in the forward deck.  He just walks up to the side of the airplane, undoes the access panel, and the pump is right there for maintenance.  Plus, the firewall is plenty strong to support the pump.

 

Otherwise, what you are suggesting is fine.
