6.2 mechanical lift pump ticking?

Any thoughts or advice much appreciated! Now i have fixed all my air leaks i think, i have fuel leaks, better out than in i guess! Getting a hold on that, but now i am hearing or have now just noticed the sound of my mechanical lift pump running, making a ticking sound i guess? Just wondering if this is normal? Or am i headed towards more fixing? Thank you in advance! Much appreciated!
