I managed to change my fuel filter today (after wrestling with it for a couple of hours) and noticed that my FPR (or thereabouts) now goes pop pop pop....( around 3 pops per second).
I think the popping sound wasn't there or wasn't as distinct as before the fuel filter change. I'm thinking that after changing the fuel filter the fuel pressure has is now higher than before and the FPR is now working harder too. But I might be wrong. Is the popping sound normal? And where could it be coming from? Do I have to fix it?
Thanks!
