Supporting Fuel Pump.

Guys, I'm trying to decide on either merging a under dash primer pump with 1/8" copper line to prime the vac tank or one of the low pressure pumps that can assist but not replace the vac tank function. Since my driving habits are casual weekends, I would have to run on the starter until the tank refilled. I'd like to limit that as much as possible.
Have any of you gone with the electric pump? . The obvious advantage is the plumbing is alot easier.
