Well as expected my High pressure pump and regulators on my 2006 vectra (50k) are knackered. vauxhall have offered to replace the regulators for free which is good of them considering it is now out of warrenty.

My question is i have heard a lot of people say that the replacement pump is no better than the original, are there any aftermarket high pressure fuel pumps that are better? maybe even a performance part to give better bang!
