Fuel Question


I dunno whats wrong but my gas milage is goin to crap lately, first time i filled it up it went 170miles and then empty, didnt really bother me, but ive been noticing the milage lately is goin down, as of last time i filled it up, ive gone 70miles but only have a quarter tank left
it needs a tune up and im goin change the fuel filter, but if the milage is still crap after that i dunnp whats wrong, maybe the fuel pump, but im not sure
any help please

yea do a tune up, plugs wires cap rotor all that shit then maybe fuel pump fuel filter, mine does the same thing but check you wires at the distributer and see if there corroded, and ckeck the gaps on your plugs.
