fuel pump ticking
new overhaul and new cam, now at 3000 to 4000 rpm the fuel pump is making a ticking noise, first I thought it was a lifter. is the new cams fuel pump lobe possibly not as high a lift as the previous cam. do they make longer fuel pump rods or do i need to replace the pump?

Replace fuel pump rod if pump is fairly new. Replace both for PM if pump is old.
You did good to find it- some say "impossible" to find.
The first time I saw that problem, checked the lash, etc.-all good.
Since I can see the engine running in my head, it had to be the fuel pump rod since the pump was new. Replaced to fix.
