Piston Seal Kit
The classic symptom of a problem with this seal is resistance on the upstroke and tendency to recoil back downwards. The piston seal is the workhorse of the pump and it's life can be dramatically shortened by overheating and a lack of lubrication. To maximise the life of this seal please follow the advice on pumping and lubrication in our instructions.
Hills Pump Micron Filter/Seal Kit
Replacement micron filter kit for MK4 Hill Pump only. This part is included with all full service kits.
