It's a mahal one as had been on here before to see probs with filters and seen cheap filter probs and pipes fitted wrong. With codes thinking injectors?

I would suggest you have a look at live values before condemning the injectors or the H / LPFP's.
If the low pressure side is OK it may be either of the PCV or VCV in the HPFP. (not serviceable) There is also the fuel rail pres sensor, but again live values will need evaluating first.
Have a look in wiki for Robbie's guide to testing the LPFP which may be helpful.yµ (idµ - eAµ) ψ=mψ

I would recommend GAP IID if you can get hold of someone with it. In a strangely similar case last year a high quality and expensive tool was used. However, after two months of testing, chasing ghosts, pouring over wiring diagrams, and replacing every part of the fuel system the problem remained.
Only then was the tool changed and a dedicated LR diagnostic tool used which found the problem and immediately identified it as a fault in the alternator!!
I have no experience of Hawkeye and it may well provide the answer you need, but be aware some diagnostic tools don't always see every fault! Whatever tool you use make sure you read the codes from ALL the modules. yµ (idµ - eAµ) ψ=mψ

It's a big leap without more detailed diagnostics to fit a new HPFP!yµ (idµ - eAµ) ψ=mψ
