Question Question of the Week #3 (Fuel filters)

I haven't checked the maintence book to see what the factory recommended for the fuel filter change, however Pelican Parts advises a change every 6k miles. Now seeing how they are a seller of Porsche parts this number is probably in their favor. What's a good interval, and what is the correct procedure in removal/installation?

I would say anywhere from 45-60K. Also, if your car is stored during winters, I would go with lower 45K intervals. If its a daily driver, you should be able to go atleast 60K between fuel filter changes.
I would consider it an item to address when doing your timing and balance shaft belts.

My 968 had the orginal filter on it at 67K miles. I changed it along with the fuel pump...just in case. BTW, one has to be careful with the metal fitting to the plastic gas tank. Don't torque too tight.

I think every 6K miles is way too often...unless you're selling filters.

It's very straightforward. It's the silver canister on the pass side rear of the car. Take off the bracket that holds it to the body, unscrew the clams that hold the hoses to the 2 sides of the filter, drain the filter (it hold quite a bit of gasoline). Install the new one by reconnecting the hoses, tightening the clamps and installing the bracket that holds it to the body. Good luck!

This is a job for outdoors. The gas and resultant gas fumes is a garage could be a bomb.

Tools required would be 17mm and 19mm open end wrenches and a flat screw driver.

A few rags, possibly a bucket to hold the spilt fuel, part # 928 110 253 06, a 19mm open end wrench, phillips/flathead screw driver, and you should be good. Like said, its very straight forward and easy. Although my car had two previous filter changes in its 170k miles, when I changed it the car ran phenominally smoother.

I would also tackle a few other maitenence items while you are back there. The fuel check valve has about a 90% chance of going bad in higher mileage cars. It gets clogged and the car doesn't get enough fuel at start up and bogs out after a few seconds. Its in the fuel tank with the pump, which leads me to the next item. The fuel pumps don't routinely go bad, it wouldn't hurt. The cars may not have many miles, but they do have age. At the very youngest, the cars are 12+ years old. If your in there, might as well do it so you don't have to worry about it going wrong.

I agree with Raj - when you do belts do the fuel filter. The car needs a routine maitenence every 30-50k miles - belts, variocam pads, fuel filter, and intake filter cleansing.
