I like this kind - (photo attached) cheap and you can change them every other time you change oil..

OReillys sells them with four really nice galvanized Corbin Clamps for 3/8" hose

This type of filter though is kind of a fire hazard, in my opinion; but all the rest of my fuel lines are steel and I only have two little 2" sections of rubber fuel hose just at the junctions of this filter so I don't worry too much.

I like that you can see inside the filter so you'll know if anything is amiss..

Not saying its the best though - actually if I had lots of money I would use the internal bronze ones for my 4160 Holley.

But one other consideration for the internal vs external fuel filters is that it is really easy to strip those fuel inlet threads in the Holley fuel bowls - the material is zinc (not aluminum) so if you tighten the fitting too much as you go to change the internal type filters - those zinc internal threads in your fuel bowls can strip easier than most people think - also the 7/8-20 threads are not repairable (cost effectively)..so you would need probably one or two new float bowls if that occurs.

Some people will tell you they used epoxy to fix fuel inlets - but if you resort to that you're then done with internal filters forever of course - and epoxy is not something I would want to risk trusting on a fuel inlet.
