What pump are you using? Plumbers test pump or a grease gun.
An update on building my pump.
I purchased a second-hand RIDGID model 1450 plumber's test pump off eBay for $50 last week. I chose this one because it's a commercial quality tool, well made, has a good replacement parts program from the manufacturer and was located 10 minutes away, so no shipping cost. Maximum pressure is 725 psi so almost double what's required for the Mini hydro system.
These pumps retail new in Oz for around $500.
Yesterday Pirtek replaced the hose end fitting allowing the Schrader valve to screw straight in at a parts and labour cost of $47.50. The pressure relief valve knob was missing so I bought a replacement general purpose knob for $5 from JayCar.
So it has cost me $162.50 all up. A litre of original formula hydrolastic fluid from MKO was $15.40
Old fluid will dump into the large plastic tub and new fluid sucked from a bottle through the inlet tube. I'll report back once I've used it in anger.
In case they are of interest below is a sales brochure plus operating instructions.
