1990 mustang 5.0 fuel filter where is it and how do you change it thanks guys mustangs rule

It's in front of the gas tank. It's held in place with a hose clamp and clips on the fuel line, should get new clips with the new filter. Discharge the line at the motor before removing it or you will get a face full of gas, don't ask how I know that.

It would be more better , if you got it up in the air like on a Ramp , or secured a jackstand an a jack to get up under it. BLOCK THEM TIRES !!!!

Yea , you gotta come back an tell us how cool it was getting gas an road dirt dripping down your fore arms , an dripping on your chest , get a tad of it in your ear, dont fer get your safety glasses
