All,
Quick Question:

Do I need to run 3/8 fuel lines or will the 5/16 work?

I'm most likely using this post filter https://www.holley.com/products/fuel.../parts/162-550

Holley Sniper - 550-510 https://www.holley.com/products/fuel...arts/FR550-510

302
E303 Cam
AFR 165 Heads
In tank fuel pump 190lph from Breeze

Guessing around 320hp

I just don't want to starve the engine.

Everyone I've spoke to has been running 3/8 fuel lines but they all have had 347 or bigger engines


Love to hear your thought s on fuel line size...

Thanks
