Default Is walbro 255 enough??
I'm in the middle of a front mount turbo fab. The shop doing the job wants to put a single walbro 255 for a grand national good to about 700 hp. Is a single enough or to I need two? I plan to run around 10 lbs. of boost. Truck has 62 lbs injectors I believe. Also, does anyone know if there is a fuel regulator that fits on a stock LQ4 fuel rail.

having two wont hurt..and i dont think there is an aftermarket regulator to fit the stock lines..just get an ls6 intake and do some aftermarket rails and put you an aftermarket regulator in

A single should be enough to max out 62lbs/hr. Stock fuel lines and reg have been proven to flow enough for well over 800rwhp with twin intank pumps.

So, I should be able to get by with one pump for around a 500ish hp range and the stock reg will work?
