QUIET external low-pressure electric fuel pump?

Yes, with a bypass regulator and a return line. Thanks for the recommendation. Actually, with a different regulator I can even run an EFI hi-pressure pump - if they might be quieter.

The GSL-392 is High Pressure. It is really quiet. $95.00 on ebay. There is a seller on there that has sold over 1000 of them. I have bought 4 from him myself.
