Fuel Filter Fittings

[Helmsy]

So as part of my "while I'm replacing things" routine I wanted to replace my fuel filter. I purchased one from our host but the bottom fitting on the new filter seems bigger than the fitting on my fuel line in the car.

It's a 1985 ROW and the filter looks the same but different fitting. What size should the fittings be on the fuel filter?

I'm thinking I may have an older/different fuel line or I have been sent the wrong filter.

I will double check the filter/part number when I get home tonight but if someone knows or could measure the fittings I will be forever greatful.

I think I remember my new filter having an adapter that came with the new one for this purpose.

It was a genuine Mahle. The fitting screwed onto the bottom and was sealed with a crush washer.

Check your old filter to see if the old fitting is still on there.

As no said, check your fittings. The other idea is that you got the wrong filter because it's a ROW car. I had the same problem with my ROW 911 SC

Thanks guys. The new filter did come with an adapter but is a lot bigger than the one on my old filter. I should take some pics tonight.

I am thinking that Rocket is right and that the ROW must be different to the other cars. Our host only seems to have 2 different filters:

928 110 147 05 for 81-89 turbos and,

930 110 139 00 for 76-79 turbos.

I checked and the filter I ordered was for 81-89 turbos.

I always went to a local place to buy the filter. This way I could see what I was getting ahead of time.
