Whatever you use, make sure it has a bypass feature if the filter media gets clogged.

 

Take a look at the Andair gasculator, a thing of real beauty. The GAS 500 has full bypass capability.

Interesting.  If the filter got clogged with flotsam and jetsam, what sam is going to clog an injector next - possibly leading to the infamous and dreaded detonation.

 

Oh, that's right, the Bendix throttle body has a fine filter, too.
