Don't know about the D2 but my D6's are all 1/2" lines.I think even the D8's are only 1/2 as well.

The fuel line is 1/2'' ID. Original was steel. The fitting at the transfer pump is 7/8'' x 14 tpi straight pipe thread... not tapered pipe thread. You can use a -10 O ring boss fitting into the pump, and your choice of fuel line or hose from there.

Thanks guys, I thought I remembered it being a straight thread, could not remember if there was a seat or 0 ring, I was pretty sure on the 1/2" steel line. I don't like using rubber due to varmints chewing on it. Thanks again. Joe Van.
