Default lt1 fuel line help

hey guys. i have a small hole in of my fuel lines and just wondering lines i should get. Im building a new motor and going to be bumping up the fuel pressure a little bit. I a have a racetronix pump im going to be putting in also. Do you think i should go with steel braided lines? if so what size do i need and what fitting should i use. I appreciate the help. Thanks

If you are running only a single Walbro pump, there is no need to run anything larger than a stock sized line.

If you are set on changing them, a -6 supply should be sufficient up to approx 750rwhp. Above this a -8 should be used. Considering the price difference, the -8 may be better so you do not outgrow it in the future.

you would need the adapter for the hard lines. you can get them at pure choice motorsports. they are part #5800 not sure if those fittings work with -8 an size hose. you'll need two pairs along with 4 straight -6 an compression hose fittings.
