Last Sat on my last run my 88 felt like it was starving for gas.I had let it run down to 1/16 on the gas gage just to save wt and the course had a big rise in it so I dont know if it just starving or if the filter or filters need changing.I put 10$ of gas in it and it ran fine on the way home.

1.? is it only the one filter I can see or are their others?

2.Any tricks involved with the filter change or is it straight foreward

3.Do I need to order a special aftermarket product,because I would like to keep it as stock as possible except for tires and shocks.

Charles, it's best not to let your fuel tank get so low. The fuel pump is actually lubricated by the fuel going through it. Running out of gas can be hard on the pump.

The fuel gauge in the Fiero is also notorious for being incorrect. Many Fiero owners have run out of gas when their gauge still shows 1/4 tank of gas!

There is one fuel filter (not counting the "sock" that goes over top of the fuel inlet in the tank). When changing the filter, make sure the fuel pressure has been reduced (as the system can "hold" the pressure for quite some time). Otherwise fuel will spray all over the place when the line to the filter is disconnected. I usually just pull the fuel pump fuse while the engine is running to reduce the pressure.

Not sure what you're referring to in regards to "a special aftermarket product". Are you referring to the fuel filter? If so, no, no need to get anything "special".

And remember that although 99% of the car is metric -- the nuts on the fuel filter are imperial. Usually you just need 5/8 -> 3/4" wrenches, and a 10mm socket for the hold down clamp.

Leave the clamp clamped.
Undo the 'outboard'/right hand nut first, then swing the line out of the way.
Then undo the left hand one.
Then loosen the clamp, and slide the filter out.

Installation is reverse of the above. Check the o-rings on the fittings that have them. Don't overtighten the fittings!!! They only need about 10-15ft/lbs (since it's the o-rings that do the sealing).
