Default 85 Vette fuel line fitting

I just bought a FIRST FI setup, and need to connect to my hard fuel lines. I really don't want to cut the stock lines.

I'm looking for a female fitting that will screw onto the male flare coming from the tank. I found a Russell Performance adapter, 640830, but I'm not sure if this will work. Has anyone used this piece, or have another suggestion?

Are you going to AN lines?

You can adapt right at the fuel filter, I think 85 needs one o-ring 16mm x 1.5 to AN (feed) and one o-ring 14mm x 1.5 to AN (return).

I assume they need the o-ring to seal to the fuel filter.

Yep, I believe those are them.

Depending where your fuel rail connection points are , you can run the new braided lines from the filter, up over the bell housing to the rear of engine.
Shorter distance and away from heat

Rodj is right, you can also copy the LT1 style and come up around the AC/heater box and over.

The only thing I don't know is how this would work with some racing associations. I know NHRA does not like any fuel lines near or along the firewall. (However this is a very common place for people to want to mount them.)
