That's a bad idea. Walbros overrun stock FPRs, and increase fuel pressure. More fuel is the last thing a stock or lightly modified NA needs.

I am interested in this answer as well. What is the stock pressure/flow rate for a stock NA engine?

^ 28.4 psi with vacuum to the FPR. 35.6~37.0 psi without vacuum to the FPR.

You can use the Walbro with an adjustable FPR set to the stock pressure. What's the point, though?
