i just change mine. to a 2nd original. i think its from B16.. for my H22A prelude.
if im not mistaken, original should be about RM1xx .. and the non-original-china made or cap ayam, should be less than that. i got mine from a mechanic, he sold to me rm60. when i fix it. the car starts right away.
i had 3 fuel relay change. 1st i think the old owner had change, and the relay now spoilt, then i change to the 2nd ones.
if im not mistaken, you can repair the fuel relay, by de-solder and solder it back. i never tried coz i have no time.
it looks like this:
