What is your question about the 89 fuel pump? I have every year FSM and parts catalogs for the Impulse.
It is on the right side of the block and very hard to get to
A stock fuel pump should not be that noisey , a commmon upgrade is a walbro 190 or 255 . from gen 2 eagle talon. these are noisey to very noisey
you have to drop the fuel tank, remove the hoses after it is lowered a bit. once completely removed open up the sending unit and pull out the fuel pump , replace and re-assemble
most fuel pumps on most cars are located inside the gas/fuel tank, unless there is an alternative fuel pump added post factory.
