I'm gonna buck convention here, but I've run electric pumps since I bought my truck in 99 and run the beloved (garbage) weber carb.  Tried different styles and different locations, and the cheap diaphram ones will leave you stuck, which sucked cause I had them mounted right outside the tank.  I've been using a holley red for about 10 years without issue.  Well, I did have issue with it starving for fuel when I tried running a regulator, but have since ditched that and it's been fine since.  And this one came out of the supposed bad pile of pumps off a generator at work, so 

Mine is currently in the engine bay across from the carb, but should be closer to the tank.  The majority of them are designed as pushers and should be run as near the source of fuel as possible.  The oem pumps always failed on the generators I used to work on cause there was often over 10 feet of hose running to the fuel tank, and some were over 2 feet deep and took a lot to get the fuel moving.  Issues were much less when I started mounting the holley pumps as near the tank as possible.
