I bought this at the car bootie last year. I guess it's a bit long in
the tooth, but it seems substantially built.
Naturally, it doesn't work properly (always the way!)
The pump runs but the water comes out in rapid pulsating spurts and
the pressure gauge fluctuates from zero to about 1/4 way round.
Any suggestions of likely fault before I strip it down and likelyhood
and source of any spares that may be needed?
