most older fords have a fuel filter on the carburator itself where the fuel line goes into it. should be about an inch or two long and have a hex to put a wrench on it where it meets the carb and nipple for your fuel line to slip on on the other end. i dont know if this is the one you changed or if it was an inline. other than that the only other filter should be the strainer in the tank. does the truck run? your fuel gauge prolly stays on empty right? i can almost guarantee you its the float in the tank. the float is made like a little barrel looking thing that floats in the gas which controls your sending unit. on these trucks they are good for wearing a pin hole in the float which causes it to fill with gas and sink to the bottom of the tank causing the sending unit to register as if it has an empty tank. hope this helps

nice reply bro

my 72 has a mechanical at the side of the block, nothing else. it just works off the cam. connected to the pump. i guess if you have an inline it wouldnt hurt, but not really needed.

72bumpside it seems like your talking about the fuel pump itself. Or do you have a filter right by your fuel pump?
I have upgraded my carb to a holley 4412 two barrel and I use a glass inline filter right before the carb. A way to test the gauge to make sure it works is to disconnect the postive side and ground the wire that runs up to the front of the truck and if the gauge pins to full the gauge is working. Bill is right about the float getting holes in them, mine was like that. But test the gauge and check the sending unit's ground also. Then drop the tank and check the float. Good luck.
