I have a '76 F-150, 4x4, 390. I did the same thing and bought a Purolator generic fuel filter that fit the fuel line. It's glass and has replaceable filter elements. That was 5+ years ago and I've had zero problems with it. The glass is great, it stays clear and doesn't 'yellow' like the plastic ones, so I can instantly check it to see if it's got trash or water in it.

How is the fuel filter not fitting? (not screwing in?, Does it hit the frame?, Is too long?) The size of the filter makes NO difference as long as the filter is clean the larger filter will not flow more. If you want to increase your fuel flow Holley makes a mechanical and an electric fuel pump for this car. If you decide on electric the Holley blue pump would be a good choice. But it will need a fuel pressure regulator. If you use the mechanial it will bolt in where the stock fuel pump is now and you will not need to do any mods.

Make sure the fuel pump is working properly and no blockage in the fuel line. I would use a large transparent in-line filter. That way you can see when it needs to be replaced. Remove the built in filter from the carb if it has one. Getting good fuel flow will effect your performace , but not impreove your mileage

You have a 351 V8 in a two ton car, your mileage will always suck, unless you put a different rear end on it. Not sure what it has, maybe a 3.90:1? If you could find out what you have and get a differential with a lower ratio, like less than 3.20:1, you'd see a rise in MPG.
Like the other guys said, get a large generic fuel filter.

Flow more fuel and gas mileage don't go together, The filter won't make much difference, unless it's for a lawnmower. Use anyone that will fit the new carb or spice it into the line.

if it don't fit get the right one or cut the line and put it on in-between the line with rubber gas line hose and clamps.well the size isn't that important just change it once in a while. it still filters the fuel.As far as the mileage keep it turned up,running at the right temperature, make sure the timing is right,brakes aren't dragging,trans is full. tire pressure is right, grease the wheel bearings. when you can push your car on a flat surface with one finger you'll have a faster car and get better mileage. and it can be done. Just keep it maintained and change your oil.

This is a really simple solution. You can go to your local AutoZone and buy an inline filter. The inline filter will be bigger than your typical filter and will allow more flow and clean the fuel properly. Give it a try. It should work no problem.

just put an inline filter in it. Hmmm, you want to "FLOW MORE FUEL"
and "GET BETTER MILEAGE"
Are you begining to see what the problem is?
A smaller filter will need to be changed more offen. Just get the filter that fits the fuel hose I.D..
