hey my fuel pressure guage in my integra is going all weird. i didnt know what fourm to post in, so im here.

when my car is off my fuel guage (electrical) needle makes grinding sound and moves up and down a bit. this is killing mt battery. now the guage has been instaled for 6 months and started about 3months ago. do you guys think it could be the wirring or the accutal guage? i dont wanna go buy another guage if its just the wiring and i havent time to pull anything out yet.

thanks
