What is the reason for turning off fuel pumps after shutdown.(a320)

[Uplinker]

.....That is the reason why the recommendation to switch OFF the fuel pumps before refueling is not explicitly provided into the FCOM, because this recommendation is implicitly covers by SOPs in standard operations (i.e. when refueling is performed before the cockpit preparation)......

my bold.

Airbus SOPs are part of "the literature" surely?

Switching off fuel pumps on the ground while they could be running dry, seems to be a reasonable precaution to me. Heat and fuel vapour can be an explosive combination !
