You can't hear much over my exhaust, so the pump wasn't an issue. I went external for its ease-of-access and ability to clean and change on the fly. Its also easier to upgrade to a high-hp unit like an A1000.

The only downside I see is that even with a small sump and some tank foam, if I'm down to 1/3 tank, I can slosh fuel hard enough to misfire if I take a HARD turn. I don't road race, but for an autocrosser it could be a downer. Some baffling would solve it as well, thats really the only thing I've noticed.
