this pump replaces an earlier version which had a cover over the gear and aluminium instead of plastic oil pipes.
The pipes are interchangeable, the o-rings are not. Our overhaul kit A-OHK-0B5 contains only the o-rings for the recent plastic pipes (sub-kit A-SUK-0B5-OP) . The o-rings for the aluminium pipes can be ordered separately: A-SUK-0B5-OT-AL - content - 4 o-rings for the double pipe set and 6 o-rings for the triple pipe set.
Plastic pipes and o-rings can all be ordered separately.
