Is inline fuel pump just as good as intank?

[Mighty Thor]

I have walbro 255 but I never got it installed. For one thing is because of Calif. emission being so strick. I failed several times already.

I'm thinking of switching to inline because it would be easier to remove when the time comes again or maybe putting a switch on it to turn it off. The only thing that would bother me would be the noise.

Currently I'm using Boost A Pump. But I want a better upgrade in fuel.

But I want to know what's best?

In tank is better.

Piggy back style still has to suck fuel through the stock pump
