He doesn't have a TBI unless I missed something.

The guy you replied to has a 93 with a stock engine, but I’m betting your reply was meant for the other guy with the 97 above that, which makes sense.

sheeeewwwww I know this thread is almost 2 years oldd but what did you guys do with the line that went to the evap crap?

You can either adapt your steel lines since they won't be a direct connection to your LS rails, or run something like braided lines with AN fittings. This is what I did, tank to rail. There are some really cool adapter fittings that will connect to the fuel rails that have a slip on fitting with a screw-in locking ring that goes behind the flange on the rail to keep it from popping off. Threw some pics below for reference.

Do you happen to have the part number of the adapters from the sending unit to AN lines? Or at least what size they are

What about the line coming from the fuel sender? Do you plug or vent it. Photo doesn’t show it connected to anything
