Yes Those Fram filters suck. Jegs carries the best cartridge/canister fuel filter out there. Its made by Perma-Cool. The Fram filters are rated at 90 gallons/per hour. The Perma cool is rated at 25 gallons per minute...So after 4 minutes the Perma cool kicks its tail. Guess what? Its the same price as the Fram new...It also has fuel/water separator, and the ability to plumb two outlets and two inlets... Lookie.. http://www.jegs.com/i/Perma-Cool/771/81794/10002/-1But Earls carries a inline fuel filter with NPT threads, or an ends, -6...-8 what ever you want..It has stainless mesh filter that cleans right up..I dont even take it apart...I just take a air hose compressed air nozzle and back flush it through the outlet side.... Its also about $40...

All fuel pumps need some kind of pre-filter or screen to keep crud out of them. Even the factory mechanical pumps had a "sock" in the gas tank. However, the filter on the suction side needs to be freer flowing than the one on the pressure side. This means making the filter either larger or with a higher micron rating or both. Mallory pumps are gerotor style so require a 40 micron prefilter (rather than the typical 100 micron). I would recommend PN 1029 shown here: http://www.robbmcperformance.com/products/filters.htmlMade in the USA, affordable, cleanable, compact and a large enough filtering area to work with a 250 pump.

One thing I forgot to mention is to always strain your fuel with a metal strainer in your funnel when adding fuel to your fuel cell. I've burnt lot's of race fuel through just a strainer in my outlet fitting in my fuel cell, but I must admit it was mostly fuel injection except for nitrous systems which I have built plenty for myself and others.
Gas is much harder to move than methanol.
