Other tanks methods will work..... but they are expensive! Our tanks are SERIOUSLY cheap!
Yup, foam will work..... but ..... costs!
The rules mandate foam for other classes of motorsport and thus, they CANNOT use a 'clunk'. Foam is not compulsory for us.... so...
NikG and Simon can get you a valving system for 4 point-bottom-feed..... if you WANT that level of complication when 'clunk' beats it hands-down at a fraction the price and complication.
Old Model-Aircraft used the 'clunk tank' method... we didn't invent it!
Don't suck the fuel up..... loosen the output end, and BLOW down the breather pipe (wrap lips round the pipe) .... this will force (blow) the fuel up....
Sucking is for suckers! Tee hee!
