Tank pumps are a pain in the rear, I have replaced a few.
Fuel injected engines often use a secondary booter pump on the injector manifold to increase fuel pressure at the nozzle. Don't know why though, and I do know part number 4047-7 is a fuel pump, thus my sneaky suspicion that 4047-2 is also a fuel pump.
