I am not just speaking for the sake of it Roger as I qualified in diesel tec and compressed air brakes tec
The fuel is pressurised perfectly not compressed as you say
If it was it is yes stronger than the metal of the pump and incorrect adjusted will destroy the pump we are talking 1600 bar 23206.04psi do you think our Ali shocks with little just fitting o rings pushed by a plastic wishbone will take that,

This isn't meant negatively . Just a good bit of debate for those who do need stuff to think about.
Cheers for your input Roger
We together will get the truth lol
I am working today on a large scaffold and a lorry has just crashed into it and driven off. Pants change required
