Yes yes, VERY nice kit, top notch! I bought 2 at the first group buy and
I'll get 2 or 3 more in the next.

Nothing more painful than any other EFI conversion. I'm finishing up mine
tonight, as long as the fuel rail cooperates it should be running tonight or
tomorrow.

Yeah I'm using the Digifant inserts from the VW, cost about 2 bucks each at
the dealer. Looked funny at me when I asked for 5....

L-Jet AFAIK. I'm using a set of 30lb/hr from an LH-Jet Volvo, and I have a
set of 36lb/hr guys from a Ford turbo coupe, same connector and O-rings.

'Bout 14mm I suppose

I know of one guy that has these in an EFI Quantum syncro. He hates the damn
things because he can't replace them cheaply....

Yes this is typically what is used....I'm using a Dodge pressure regulator
that gives 55psi base, so my little 30lb/hr injectors will flow a bit more
than 30.
