Default Fuel pump replacement 89S4

It appears that it is time to replace the fuel pump (very noisy). It also appears that there is a wide variety to chose from. Any recommendations on one (or ones not to)?

'89 is the first year Porsche put the in-tank pump back into the vehicles.
When the in-tank pump goes bad, the main fuel pump will get very noisy.

If you want to not replace the in-tank pump (very pricey), order a strainer from an '87-'88, the different feed hose from the strainer to the pump, and a main pump for an '87-'88, not an '89.

No, just use what is there unless the rubber buffers have deteriorated.

If your intank pump is still running, most likely the hose that connects the metal strainer/filter pump assembly has failed. Greg has a hose kit to replace the hose for good. Roger has the it in stock. If the intank pump is dead, follow Greg's advice.
