<VV> Healthy pumps?

[Bryan Blackwell]

Right, what I meant was that *if* you used the eccentric to create  
the pressure directly, you'd need some sort of relief valve in the  
pump.  Which could fail.  Leading to *bad* things.

The way the pump is actually designed - using the spring to create  
pressure - is much better.

BTW, if you're going to heat the the spring with a torch to soften  
it, take it off the engine first :-)
