Im in the same boat Im looking at probaly one bad GT 40 fuel pump. Do I swap both for AEM 320's or just go one AEM 320 with a BAP......
Was told that the AEM pumps should stay under 16 volts, so wouldn't recommend it with a BAP just get the two AEMs pumps and call it a day. Should support what ever you plan on doing.
