On the market now are so called "fuel savers". They basically are just two pieces of magnet that attach to your feul line,on the outside,no need to cut.They claim 27% to 30% savings,and customer feed back is even more.I looked them up, and in indepednent tests on a rolling road, there was not one single difference.They are supposed to line up the fuel particiles,so they go into the chamber more compact, thus bigger combustion.A metal fuel line it wont work or metal at all on your line de magnatises it.One guy said one of his young labourers on a building site at dinner time,broke up a magnet into 16 or more pieces and taped them to the fuel line on a petrol minivan,seemily the minivan was jumping with added power.Other people claim if you put 2 or 3 on they can increase your bhp by 20bhp.they range from £30(rip off)to £3(more like it).Any one ever tried one of these,tell us your results,any way of saving fuel is very interesting lol.
