I have a 92 civic hatch with ls vtec 95 ls/bock with 99si head adjustable fuel regulator s300 tune. I was running a stock fuel pump it went out today can I install a walbro 255 or will it flood my car with to much fuel. Or can I tune it down with the regulator.

 

im not much into tuning the computers and stuff but ill tell you what i can. i know a 225 will flood you stock.... but u might be able to tune down your regulator. the thing is you have to drive it to tune it. thats just my .02

 

I don't think it would. I'm running a 255 walbro with my stock GSR.
