baffled tank, Do I really need one? Working on a 63 Corvette LQ4 conversion. I have all the components for the external fuel pump, regulator, etc. I don't plan on racing and usually keep the gas level up. Do I really need a baffled tank. They are pretty pricey. Thanks,
Scott!

Not really. The C2/C3 corvette tanks are deep and even angled toward the pickup. I've been well under 1/4 tank and not had problems. At 1/8 tank, it will stumble on cloverleafs.
I also just did a 72 Olds 442. That tank is low and wide. I doubt I could get away without one there, so I put in a sumped tank.

One other option is to add a remote style serge tank. You run a Carb style pump (low Psi high volume) from the main tank to the serge tank and your high Psi pump draws from it feeding your fuel rails. I make them around a quart in size maybe a little larger if you have the room. Can be mounted in the trunk or under the car. The return line from your fuel rail feeds back into this serge tank and you also run a spill over line back from the top of the serge tank to the main fuel tank. Works very very well. We run them in all our off road vehicles and most of our street builds.
