Hello. Where do i start searching for realistic looking "fuel filters"? I do not have old electric equipment i can use as donor. Maby there is any online shop who offers in the right size and do maby sell a batch of 10 or 20? I`m not sure what the electric components are called in English,so if anyone could give a tip on what search words to use, maby at Ebay or such it would be great. Thanks. Tommy
