Don't confuse an OEB regarding the use of Centre Tank pumps that had a problem (screws loosening and causing a potential electrical short) and now withdrawn for all pumps that have been modified (locktite!) with a load of BS about fuelling being slower with the pumps running. I have it staight from Airbus Flight Ops that this is not true. The FCOM on cockpit preparation clearly states "all while lights out" which includes switching the pumps ON - no mention of not doing it while refuelling. Some folks bring old habits to new airplanes and it aint any help! There is no evidence that fuelling with the pumps on slows the refuelling process so just do as the manufacturer suggests - unless of course you know better!! Those guys are usually the ones who don't want to comply with the SOPs too.
