everyone needs a fuel filter. all u need to do is cut ur fuel line in a good spot, so that when u install the filter, it does'nt intefere with anything, like servos and pull starts. get some small zip ties to keep it attached.

you don't need it to run your car, but it would be a good idea and will make your engine last longer

last ALOT longer.

yah i got that and it didn't work, but i had it on the wrong way

lol, if you buy a new fuel filter, most of them they will owrk either way, just when you clean them, hook them up the same way u took it off, and put the filter inside it the same way, so that if you didnt get all the dirt out of the filter, it wont go back in, but if you do out it backwards, u have a chance of getting dirt in your engine
