Electrical Fuel Pumps

Hi everyone;

I have attached two photos from the maintenance manual (chapter 5-10 and 5-20 Life limitation) 

in the first photo the manual says that the fuel pumps should be replaced every 5 years with out mentioning the type of the fuel pump (mechanical or electrical)   then few pages after that (5-20-00) page 15 its shown that electrical fuel pumps to be replaced every 1000 hours.

i have 914UL engines equipped with electrical fuel pumps, what is the time limits for these pumps ? is it 5 years as mentioned in the first photo ?

or 1000 hours as mentioned in maintenance schedule?
