So I have a 2000 Toyota Rav4 and I have been trying to get my fuel filter on for hours now and can't seem to get it tight enough for it to stop leaking. Is there a trick to it or is there anyway that I got the wrong filter? It looks just like my old one. Also would fixing the fuel filter even fix the problem. I was heading home from college and at first it was running fine, but then at a stop light it started to idle really rough and then when I went to take off it felt like I wasn't getting enough gas and acted like it didn't want to go but still did, till thankfully when I got home. I just want her running again.
