{{{ fuel ine size }}}

Just up psi some.

Everybody's always wanting to upgrade when really it's unnecessary most of time, like if it says 'race' on it, it must be good....

While in -MO-yes there is consideration in that it has dual carbs..
I know a lot of people still running 5/16 including myself, from built 440's, 451's,410's ect..
I bury the speed-o into the 120mph mark on wot runs, I've never ran out of fuel and thats with a stock pump-5 1/2-6psi

Really one of the main ways to find anyhow is to try it before and after or have some gauge in the car to see the drop while also regulating the psi-meanwhile obviously paying attention to any premature laying over/flatting or basically cacking out in the R's.

but what do I know...
