on my 52 the original owner over the years had replaced the fuel pump with one that did have have the fuel screen on it so he added an inline glass bowl fuel filter at the inlet to the carburetor. since the carburetor inlet and the horn was in direct alignment he had to bend the horn bracket down at a sharp angle in order to have enough room to fit the fuel filter. when i replaced my fuel tank with a new one it eliminated the rust problems associated with it so i replaced the fuel pump with the correct pump with filter screen, removed the inline filter and moved the horn back to its proper alignment. looks much better.
