Switching from mech to electric fuel pump 85 c10 vortec block

[9511234]

Ok,  so I've got an issue.  I'm looking for the best place to mount my fuel pump.

I have a Holley-style pump.  I have dual tanks.

Only reason I am changing the pump is due to not having provisions for a mech pump in the new block. 

If anyone has pics or has done this before it is a bonus.

As close to the tanks as possible. I would imagine right after the selector valve.
