Gday , I put a new fuel pump in my vn ss and changed to single hi pressure internal , all was well except after a week started making a clicking/light thump noise only while on the throttle , the noise speeds up according to throttle. It is coming from the rear right side near or in front of tank , sounds like it is tapping on the underbody. It didn't effect pump performance , I changed pumps today and chucked on external and the noise is still there. Could it be a metal fuel line seeing as it is varies only on throttle , possibly loosened from pump changing etc? , I have also done rotors and pads but they seem perfect. Any ideas out there? Any help hugely appreciated. Cheers.
