I could turn lights on and let fuel pump do its thing for a few seconds, then start tractor and leave it in run position after starting. This tractor would rarely be used after dark if at all. Please give me your opinion as I value it very much. Also, is this the correct in line filter for this tractor? Thanks so much and have a great day.

Electric fuel pumps are normally mounted as close to the tank as possible because they push fuel, they don't pull it.

Also, they only operate when pressure in the line drops below a certain point (i.e. when the carb needs fuel).

When they do operate, they make a clicking sound.

I'm trying to get a grasp on how you are hearing the clicking through the hour meter, but my guess is that you are hearing the clicking direct from the pump because you have it mounted so adjacent to the operator, near the dash tower. The clicking is probably somewhat amplified by the metal of the frame and dash tower.

You might try unbolting the pump from the tower, let it hang loose, to see if it alleviates the noise. You'll need a temporary ground on the pump.
If that works you can try rigging some type of rubber mounting arrangement.

What he said, you can't hear it when a 1512 is running due to the engine noise. You can disconnect the hour meter + terminal and see if it is still noisy.

Thanks to all that read and responded. All of you are spot on. I went to the garage and unhooked hot wire to meter, fired it up and I could not hear the noise in meter but could hear it coming from pump. Amp gauge still flickers at idle but light goes out after increasing throttle. Now I have to get the mower deck on before I imagine I am hearing another problem. Wish I were as Savy as you members.
Thanks again and have a great day.

It would be best to power the pump via a fused relay. There's also some safety issues you should consider if the engine stalls. Here's some great basic knowledge.
