I have civic 90, the problem is when i convert it on patrol, it runs few meters and then stops as if fuel is not coming, i got it checked with different mechanics, some said, its cng conversion problem but after even after changing the switch, prob remained same, some said its fuel tank n lines blockage so i got it cleaned n replaced lines, now mechanics are saying its due to fuel pump problem, replace it with japanese pump not chinese.
i m going 2 replace it today, should i buy new one or used? any price idea? what about electronic fuel pumps, is it more effective?
