Electric fuel pump dual polarity Made in Germany with modern, reliable, electronic, solid state switching and control which eliminates the use of contact breaker points. Plus the diaphragm is made of an ethanol resistant material unlike your old SU pump. With the new fuels they will attack non protected rubber in your fuel system. Now you can have a vintage looking SU Style fuel pump with peace of mind that only an electronic fuel pump can offer. Plus the characteristic ticking is retained. Over time your old SU pump slowly pumps less and less as the diaphragm and internals wear.
