You don't need AN fittings to run an electric pump.
If you want progressive fuel delivery you can run a controller or a newer Holley progressive pump OR run a return line.
You don't have to have a loud or even audible electric pump.
This is 2016 and technology has come a long way. Me...I embrace it.
Look at it this way. ALL new cars, "street cars" if you will come with electric pumps. And for good reason..
IMHO, the little bit of extra wiring is well worth the benefit of having stable, fully controllable and on demand fuel that a mechanical pump simply cannot provide.
