Another thing most want to be drivers forget if you don't know that pump back to front don't worry about driving!
I'd go a step futher than just the pump. How many times have we seen people
focussing on the noisy attention-getting thing, when the problem is a leaky
seal or mis-set valve further back in the plumbing ?
I reckon that's one thing the Norte Americanos have got right - on paper,
anyway... it's Engineer or Driver/Engineer - Someone who understands the whole
appliance & can be relied on when it breaks. not "just a steering-wheel
attendant" (to quote the irrepressible Broady).
