Replacing HPFP, need help finding TDC


Recommended Posts

Hi guys,

I’m replacing my HPFP on my 2015 5.3 and was told it has to be installed with the cam TDC. What’s the best way of doing this if I don’t have a camera to see the rod move or if I don’t have a pump alignment tool?

Scoll down to post #61.  I'm JonblarC7 on there too.  You'll see how I used a socket flip around on a extention to figure out the Top dead center of the lobe.  This how I measured for the lash cap after my cam install.
