Have -6 lines all the way. Going in a steet/strip car. Thank you for advice Last edited by cudacar340; 10/04/16 06:19 PM.

I'm still running stock 5/16" line. https://m.summitracing.com/parts/crt-m4862 Last edited by StealthWedge67; 10/05/16 02:25 AM. LemonWedge - Street heavy / Strip ready - 11.07 @ 120

It's not as much psi as the one above (5-6 IIRC). I also used 5/16 line to the pump and 3/8 from pump to carb. Runs 11.19's @ 121mph in 3520 lbs. '63 Dodge 330 11.19 @ 121 mph Pump gas, n/a, through the mufflers on street tires with 3.54's. 3,600 lbs. 10.01 @ 133mph with a 250 shot of nitrous an a splash of race gas. 1.36 60 ft. 3,700 lbs.
