Yes it should mount up, but who knows what the Chinese hutzl guys will send you.

Pistons and adjuster screws may be way off, so the pumps outputs are below standard flow rates.

Be our AS guinea pig & order some!

Over the years, I have seen those OEM Stihl oil pumps come in with all plastic driven gears & no lip seal, modified pump pistons, and modified adjuster screws, all without updating their part numbers or listing the piece part changes in a technical bulletin.
