a buddy of mine just recently got a 86 951,
began hearing constant whirring type noise in rear hatch area.
he told me that he found a SECOND fuel pump on the passenger rear side
only accessed from a compartment under his carpet area at the hatch area.
he said a reputable mechanic told him.
i am no porsche mech.,but all the manuals and pet programs i have accessed
have never shown a second fuel pump.
is my pal full of **** or is he right?
thanks,

The "second" fuel pump he is referring to is actually the fuel tank level sensor.

Yep, level sender.

thanks for info.
if it goes bad,
can that affect engine performance to a great degree?
does it look very similar to the fuel pump?
thanks for help.

It has no affect on the engine at all. It's only function is to send a signal to the instrument cluster.
