Pump & Inertia switch

Guys -
Not being the sharpest knife in the drawer with things electrical (or mechanical, for that matter...)
Since my 300 six has no provision for a mechanical pump on the block, I'm considering moving the little Edelbrock pump back to nearer the tank and incorporate an inertia switch with a relay.  Do you think this relay circuit will work?

Yes, that should work well.

Thanks, my friend!
