Im looking to build this surgetank to sit under the car, i got 4 inch pipe around 2 liter volume, I have some ideas on the baffles but not sure if it will be enough to stop fuel moving around, it should be full most times but when under constant throtle on off.
What do you guys think?

 

Check out ASP's surge tank setup, maybe use as a guide line for your setup https://honda-tech.com/forums/welding-fabrication-53/fuel-surge-tank-1485767/
