Yuck, you should really keep it efi. But a regulator with a return would be ideal rather than trying to choke off the pump.

Without the return line hooked up you will burn up your elec. fuel pump.  Advance has a holley regulator you can buy for around $35 or so.

no. you will need one with a fuel line return provision.

Theoretically the pump will work harder until line pressure rises high enough to open the dump valve back in the tank. You'd be better off just running a $15 mechanical pump
