While I was re-assembling my 461 the other day, I noticed that the impulse hose was pretty hard, so I swung by my Stihl dealer today and got a new one. When I pulled the old one, I noticed they looked different. Turns out he gave me an 1127 impulse hose, not an 1128. The new one is about 3/4 of an inch longer and appears to have a smaller id. Can I just install the 1127 and not worry about it or should I return it and get the correct 1128 one when the rest of my parts come in?
