For surge tank primer pumps, anything will do for most situations, I mounted my surge tank under the car and gravity through 3/8th tube (bigger than 1200 standard).

So any low pressure electric pump will do, the Bluebird pumps from the L20B equipped ones is what I'd recommend. $10 from the wreckers.

For the main EFI pump, The VL external pump is ok, but if they run at 12V all of the time, they will ALL overheat in summer in traffic. If you don't believe me, you will be cursing my name when it does happen to you. I had brand new ones and second hand ones behave exactly the same when the temperature got over 28degC. The fix involved using a 1200 ballast resistor, a relay and a switch on the dash.

For my new install, I've cut the side out of the 1200 tank, fitted a swirl pot in the base, and fitted a intank pump. The petrol keeps the pump cool.

Cheers,
Chris
