Help! Leak Around CRDI HP Pump

Fellow Tsikoteers, good afternoon!

I posted a question sa isang thread dito. It's about fuel filter replacement for a 2008 Sportage CRDI.
Napagawa ko naman sa isang shop sa may Motortown, ATC. Isinabay ko na sa change oil. Okay naman, di naman gaano kadumi yung fuel filter.

Nung matapos ang service, pinatanggal ko yung engine cover to sheck a leak that was spotted by the previous mechanic who did the oil change.
Now, as expected, andun pa din. The leaks are from the injector tubing or fitting na but mostly sa may high pressure pump. Nung sabihin ko sa
mechanic na I experience some engine noise (somewhere between humming and rattling) during low rpm's, baka yun na nga daw pump ang may
diprensya. DI naman nila daw kaya yun kse wala sila diagnostic or calibration tools for CRDIs.

Any advice po? I also read somewhere here (sa Hyundai forum) na meron nagparepair ng HP pump. Baka meron senyong nakaranas ng kaparehas ng case ko. Maganda pa naman manakbo, esp. pg highway cruising speeds, banayad at di maingay. At di rin naman nagbago ang consumption as before the rattling at low rpm's, nasa 11-12 mixed. Pero ung ingay nga at yung leaks ay syempre cause for concern

Please help. Thanks in advance.
