fuel filter

I just bought a 1985 Crx & need help locating the main fuel filter. Ive looked under the rear of the car,but I cant find it.
Thanks for any help!

there should be a plastic cover to hide it. being held with 10mm bolts. the filter should be on a bracket attached to the car. i had to take off the bracket with filter. hope it helps.

The '85 Si has only one fuel filter, it's on the passenger side mounted on the firewall. It's black metal.

In the engine compartment, not the rear.
