I been looking for the correct fuel pressure for a 3800 s II n/a and can't seem to find an answer in my searches. There is a lot more info for the s/c but not the n/a. What fuel pumps are people using for the n/a i see alot of people are using the walbro 255 lph for the s/c, could you use this for the na or would it be over kill?

thanks

GM service manual indicates 45-55 PSI at the rail test point. Can run as high as 62PSI, but the average on modified engines with the stock injectors is 58PSI

The walbro 255 will be fine.
