Some of the glass filters are not small micron filter and I do not recommend some of them but the G3 Fram is plastic and filters very well and flows very well. Or get the WIX or NAPA 33003 it is also see through and filters well these are for 3/8" fuel hose. You must protect the carb as the smallest debris can get between needle and seat and make the fuel not shut off and you get dribbling out of the carb boosters. Carb boosters are the legs that extend into the holes or venturies of the carburetor. 4 barrel carb= 4 holes or 4 Venturies. Now those holes are not open where you could stick a carrot through them, it is blocked by another round object which is smaller this is the booster, it has a leg on it tubular shaped and attached to the body of the carburetor. In the middle of the booster is a small tube that is like a straw it is brass and fuel will dribble out of it at idle if there is an issue with too high a fuel level which could be caused by a needle and seat not sealing off. Now you can look down the carb at idle in park and then while looking you can rev it up and watch the fuel come out of that brass tube. it should flow from both front boosters at the same time. Annular discharge boosters are different looking but work the same. No brass tube but instead have holes around the perimeter. If you have one booster that comes in at 1100 rpm and the other one comes in at 1700 rpm you have an issue . Dirty carb. Internally there is junk blocking some passages. I tried to explain that best I could. Have fun. Get a filter on it before the carb.
