I am very excited because I am picking up my '86 944na that I bought last fall next week. The PO was storing it for the winter.

One of the first things I am going to do is change the fuel filter. The PO thinks it's original...ewwww.

If that's true, I suspect the fittings or lines it attaches to will be pretty corroded with age. Is there anything that I am likely to break that I should have on hand before I start?

Thanks in advance.

How many miles? Mine had 59K, and it broke loose easily enough with two crescent wrenches.

My '86 with 90K also broke loose without and trouble. You'll probably be fine.

Mine too broke loose fine, with 116K miles (I don't know if it was change in between).

One thing to remember - make sure the FLOW arrows or words line up with the original.

I think Porsche made it idiot proof, in that the two sides are not the exact same size, therefore won't fit. But just double check anyway. My MANN replacement looked slightly different then the old part, so double check.

Mine was seized and I kinked a line! Try soaking the threaded ends with pentrating oil a day before you change the filter, and use two wrenches at the same time on each side.

Mine was also a very trying experience to remove at about 75,000 miles. Fortunately I did not damage any lines but I obliterated the existing filter during removal. I never thought that I would be so happy to have gas from the fuel filter spill on me.

If in doubt, I would do as suggested by PorscheG96.

Also, you may want to see if you can use brake wrenches – if they fit over the lines then you will get a much better fit around the connection on the line sides of the filter. If I remember correctly (its been awhile) I used a brake wrench on the line sides and a pair of vice-grips on the fuel filter side.

Try PB blaster for a penetrating oil.Walmart sells it.

Thanks for the advice, guys. Looks like it requires technique, not spare parts. <img src="graemlins/beerchug.gif" border="0" alt="[cheers]" />

I managed to unscrew the flange from the old fuel filter on the gas tank side, rather than unscrewing the filter from the fuel lines. Once the filter was off there wasn't enough of the flange showing to get it out, so I unscrewed the flange from the new filter and installed it onto the old one. Seems like it's working fine, but I'd rather have done it the right way. That'll teach me to try and unscrew anything that hasn't been Liquid Wrenched.

BTW, when you get the old filter off, pour a little bit of gas through it backwards. You'll be amazed the color of the stuff that comes out.

a good tool to have is a flarenut wrench, they fit over the nut and save knuckles. I bought a 19/21mm craftsman one for the job.

I was deadly afraid the rubber hose would break. With 16 years it was looking very decrepit. Nothing broke, but it still bothers me today.
