This is a rare Herbert Fuel Injection Blower Hat that should fit 6-71 & 8-71 Blowers. The unit comes as you see it with stainless steel fuel lines, injection manifold plate and paperwork. It appears to be in superb condition considering they were made in the 60's with only around 60 being produced.
