Just thought I would mention what I have just recently gone through.
My fuel gauge line is connected to a small needle vale on the fuel pump and over time, the gauge needle valve has vibrated open.
I started to hear this tick while driving and thought I had an exhaust manifold leak. Kept looking and checking and found nothing out of the ordinary. This went on for a while and I was getting frustrated and concerned due to the exhaust burning metal away at the gasket area.
One day I happen to watch the fuel gauge as I booted it to pull away in traffic and the gauge needle jumped in time with the "tick" - ahh I thought, has to be the gauge line valve.
Adjusted the needle valve until it was almost closed - still the same. Finally adjusted it until the needle valve barely lifted off the seat and that fixed it. It appears that the needle valve spindle had moved (turned) from the fuel pump/engine vibrations to the point that I found it. I guess close to half a turn of movement I finally got.
It sure had me concerned for a little while and I can see how someone would think there was something more serious happening - even to the point of taking it to a shop for a diagnosis - could be an expensive mistake if the wrong shop was picked.
Thought I would post this in the hope it might stop someone else from making wrong assumptions.
Truck runs great and no more apparent engine "ticking" :-)
