http://store.knfilters.com/search/product.aspx?Prod=81-0241 This K&N Fuel filter is perfect and allows you to get rid of the "hidden filter".
It's 5/16" barbs and easily fits between the petcock and top of carbs.
It's clear and you can easily see if you got into some junk fuel.
And only $6.38 direct from K&N.
