Hi all - just wanted to say thanks again and provide some closure for this thread. The Tangerine kit was just right, though the adapter was a lot longer than it needed to be (for my car, at least.) I replaced all plastic with stainless and the job was pretty trouble-free -- no surprises or leaks, and nothing broke mid-repair or otherwise went pear-shaped.
As it turns out, however, what I thought was a jagged, broken end of the plastic supply line turned out to be a trimmed, crimped end that was crimped so that it would squeeze down into 7mm fuel line . . . I just couldn't tell that when it was spraying fuel all over me. (Thanks for the booby trap, previous owner . . .
)
The 914 is back on the road & ready for some more miles. With any luck it'll be my commuter this winter.
