Re: convert to electric fuel pump
I'd think a 1.5 would be fine. Be aware of the different filters as some will need higher pressure to flow. Likely a difference without distinction, I guess, but if you do have a problem, check the flow with and without filter to make sure a picky filter is not causing difficulty. Just flow into a container before the filter, and after for comparison.
Some pumps have internal switches that de-power the pump when there is no demand, applying power only when the pressure drops below a specific set-point. That saves energy, wear, and also will stop the pump in case of a roll-over or other difficulty. As long as the fuel line is intact, and the float bowl needle & seat working it will stop pumping. OTOH, flip, and the pump will continue to pump.
I would take a look at the wiring diagrams for any that have a powered pump to see if duplication of the safety switch system could be reasonably done. Definitely get a 'rollover' switch from a junkyard for a few dollars. Who knows, it may prevent conflagration. They are mounted under the glove box, behind the top edge of the carpet/floormat on the firewall or toe-board in Ranger trucks, and should work fine for your application. Cheap protection.
