If i change the fuel pump do i have to change the fuel sensor?

i think i might have to change my fuel pump but somebody was telling me if i i change the fuel pump that i have to change the fuel sensor and it would cost about 300 dollars is that true? i have a 95 s-10 chevy

not true
If i change the fuel pump do i have to change the fuel sensor?
You should not have to change out the sensor, is your fuel pump is in the tank or on the frame rail, if it is in the tank it might have the pump and tank level sensor as one unit, if it is in the frame rail then no, you just remove 2 or 3 fittings and change it out, simple repair, harder if in the tank, as you will need to drop the whole tank to get the pump
If the fuel pump is in tank, examine the outlet of that assembly and see if there is some corrosion, if so then replace all. It'll save you time later if that outlet should start leaking.



I don't think that whole assembly is 300 either...
95 s-10 you can replace just the pump alone. But, the sending unit lines might be rusted and may twist off when you remove the lines, unless it has quick disconnect fitting on the sending unit, but I don't think it does. The only reason you should have to replace the complete assembly is if it is rusted or the fuel level sending unit doesn't operate properly.

I really must advise against using aftermarket fuel pumps like from Napa, Carquest, O'reily. I am member of the International Automotive Technician's Network, and I see dozens if not hundreds of repairs on all gm vehicles, especially trucks, where aftermarket pumps were used and came back with multiple problems. Save your sanity and time and use a genuine AC Delco pump. You'll thank me in the long run.
