Interesting news on the parts availability - I guess I should call some dealers. I think part numbers can be had fairly easily.

The fuel pickup filter I used is a Carter STS-79. The line is SAE (closest equivalent to the metric on the pump armature) as are the fittings. I've always had good luck using SAE lines in place of metric, often swapping the fittings from the old lines if I need them (in the case of brake lines etc.)

Hope this is useful for you.
