Can I use a Walbro 255 fuel pump and a carbed LS1?

I never said it wouldn't work, I know it's just a matter of getting the pressure down so you're not spewing fuel out of the carb. I'm just saying from a Dollar and complexity POV it's better to just get a pump that's designed for being used w/ a carb' to start w/.
The stress I mention is, whatever FPR is going to reduce ~60psi down to ~6psi is going to be under a lot of stress to do so and wouldn't expect it to last very long... unless you spend TeXa$ to make sure it's of great quality. But then that defeats HIS reasoning for wanting to run his 255... to save cash.

On the return style regulators, can you mount them close to the tank? Or do they need to be mounted closer to the carb?

I am doing something similar to this on my chevelle. I have modified the stock fuel tank for an in-tank high pressure capable pump. There is a return style bypass reg right at the tank set at 15 lbs. That keeps the fuel line to the front pressurised at around 15 psi. Up front at the carb there is a deadhead carb-style reg that drops the pressure to 5 psi before the carb.
You might be able to get away with just the single bypass reg at the tank set to 5-7 psi, but I wanted

Hey great everyone! Didn't know it would turn into such a debate! But I was looking at using the Mallory regulator. I used my stock chevelle tank with a baffle and plumbed my return line back through the stock sending unit. Ill post some pics soon.
