I've been in a search for an inline fuel filter but have come short. After a recent leak from my carb and discovering sand in my carb i've changed my stock filter to a k&n w/outwears and want an inline fuel filter. The problem is all the visu-clear filters come in 1/4 and 3/16 and 5/16... The gas line is about 3/8"!!! I've tried lawn mower shops, ATV shops, and motorcycle shops. All i've been able to get are gas filters for cars, which are too big. Where can i get one that fits?
