FRAM G4168 or Hastings GF97 if you can find one or its equivalent. Check your local Autozone/NAPA/etc.

http://www.ebay.com/itm/Fuel-Filter-Has ... HC&vxp=mtrSearch for the other x-refs and you may find one $1 cheaper.
Make sure you buy
fuel line, not air line, not cheapo clear line, etc. Needs to be the right material otherwise its prone to hardening and/or breaking down. Something clear or semi-tranparent is nice so you can SEE the fuel and any air bubbles. The NAPA up the road form me sells 3-4 different sizes of fuel line, all of it is a slight yellow colored transparent tube.
