Default quick disconnect size on LS1 fuel rail
I'm ordering my fuel fittings/lines right now and I need to know what size the quick disconnect is on the fuel rail of an 02 f-body LS1.

Thought so.

Where is everyone getting they're quick disconnect to AN adapters? I have quick disconnect adapters that I can put regular rubber fuel line over but I'd rather go with AN line.

I'm using the Russell quick connect fittings, but I don't like 'em--they don't fit very well. I'm going to replace mine with compression/AN fittings eventually.

I was using the Russell Q/D.. but got rid of it in favor of brazing on a AN -6 fitting right on to the Fuel rail.. that way I know I have a good seal and doesn't stick out as far.. and for most of the people, how offen do you really need to disconnect the fuel line ?

advance and autozone have the female quick disconnect with a male barb for normal fuel line, 3/8 and 5/16....look in the "help" section for gm/ford/chrysler quick disconnects.

Already have a set of those, I'd rather run AN line though.
