fuel pump for Rover V8

[clint888]

Have just fitted uprated cam and induction kit to my 4L Chim. + tornado chip but no burning in as yet. Cam instructions say increase fuel pressure as makeshift measure. I could squeeze the present regulator a bit but it would be easier to fit an adjustable one. Anybody done this and,if so, does it make a ha'porth of difference to performance? It goes like a rocket anyway with Mark adams' chip.
