I have a b18c in my civic hx. I believe the civic stock fuel pump is going bad. The b18c is basically stock besides light flywheel and clutch and exhaust. which size fuel pump should I get 190lph or 255lph? I believe the itr stock pump is 190lph? but through searching I found 3 different claims of lph's. is a 255lph just too big or will it not matter? Thanks for the help
