987 fuel filter

[paulv]

Being my first Porsche, I noticed that my 07 987 doesn't have a fuel filter, but the 986 family does. Can anyone shed some light on why they omitted the fuel filter design from these cars? I know that many gas stations have filters on their pumps -- maybe that's the reason.

Thanks.

It still has a fuel filter but it's now integral with the fuel pump/sender unit. Don't really know the whys of it all but heard it has something to do with cost savings.

The MY2002 Tech Book says:

The fuel filter is integral in the tank unit and no longer requires changing. A reduction in deliver rate can be detected via the mixture adaption.

Since they now have about 5 years experience on the "no change fuel filter" -- it must be working...

Loren, does the 997 use the same set-up?

I would feel more comfortable with say....10 years experience.

Porsche calls it the returnless system. It started in model year 2002.

Prior to that time the fuel went in a loop. Fuel was pumped from the tank to the engine. Unused fuel then returned to the tank. The fuel coming back to the tank was therefore heated during the trip to the engine.

With the returnless system only the fuel that is needed is pumped to the engine.

Thanks everyone for your replies. Looks like one less scheduled maintenance item to worry about.

OK; I just had some 70K service done on my 2006 987, no problem.

But, in the recommendations box it says to replace the fuel pump and filter.

Dont understand how that could be recommended on an excellent running. 987 !

any thoughts ?

Your fuel pump and filter are inside the gas tank.

I would not go in there unless you are having problems. It's easy enough to measure the fuel flow should a potential problem arise.

Hmmmm; I just had some limited service done at 70,000 miles. They recommended replacement of the fuel pump/filter. When I asked what that is based on, they didn’t have an answer. Well $1,000 worth of parts and labor needs solid justification.

My gut feeling is the pumps good for 100K miles. 
And this was from a well known local Porsche garage….
