The o-rings on my fuel filter bolt are worn out and leak. I have an 85 300SD turbo. The part numbers I have for them are 000 997 00 48 and 003 997 58 48( are these the correct part numbers?), the first one (the larger of the two) I can find and order online with no problem. the second one that keeps the raw fuel from crossing over into the filtered fuel I can't find a source for. does any one have a source for this smaller o-ring or a substitute part that I could get from a local parts house?

Take the both off and to a local hydraulic hose shop. They have LOTS of o-rings - get Viton o-rings. If they don't have the exact size, buy a couple too small and too large. O-rings aren't critical in size, they don't have to be a perfect match, just pretty close.

You could always use the dealer it cant break the bank!

Those are the correct part numbers.

There are several different bolt configurations depending on the year.

Get two of each o-ring and you will have all possible configurations covered.

Thanks for the advice, went to Harbor Freight and bought a complete set of metric viton o-rings (12.99 + tax for 180 various sizes) found the exact sizes needed and am currently leak free with plenty of extras.
