Carl, I have a complete set of flare type non-Jake fuel tubes if you need one.  I think the flare type are more prone to cracking than the o-ring type.

I had fuel leaking into my oil on my 671. It wasn't the more common problem of the fuel lines as have already been suggested.

I had 3 injectors that were leaking fuel through the injector seal. The seal (O-Ring) was so old and dry rotted that fuel oozed past.

I removed all of the injectors and replace the seals...
here is the video I did of the seal replacement.
