I strongly suggest you fully understand that before adding one.
Thanks Scott, I can understand the safety case behind it, I also see that most 12 owners regularly pull the fuse to stop the noise

It is either make a neat lanyard for the pump fuse and an enlarged 'knob' or install a switch prominently marked next to the start switches.

Thanks all for feedback, most helpful.

An “Aux Fuel Pump Switch” is great for on ground work such as regular software updates etc. or when running fuel transfer pump from aux fuel tank (at altitude)....but i’d Keep the aux fuel pump running @ all other times.

Looking at a red light next to switch when pump OFF. Switch will be matching Otto switch just above ignition switches.

You can only protect so much from dumbness

To guard against dumbness/forgetfulness and make fuel pump fuse almost foolproof... anytime I remove the fuse, I tape it to the pilot control stick. No switch or light to look at. I think I would notice the fuse even with winter gloves on.

If you don't have Nav lights the Nav light circuit works great for the fuel pump. I did mine that way about 5 years ago and haven't regretted it. I took the old fuel pump power and put it to a new 14VDC socket that I installed on the ELT antenna bracket and took the unused Nav light power lead and ran it to the electric fuel pump. Then I relabeled the Nav light switch and fuse. It brought my standard operating procedures more in line with my Cherokee. Another thing I like is that if I do experience vapor lock I can turn on the pump. I run it routinely for takeoff, landing and during climb out on hot days in Phoenix, but most of the time it's off. The major reason I did it was that I was afraid the mechanical pump might fail and I would not know until the electric pump failed and the engine quit. I understand Scott's logic, and I just think the risks on my approach are less. You know what they say about opinions.

I believe that the statement is -

Opinions vary.....

Sadly, we have the new led lighting which has power supplied down elve's hair wiring

Like the thought process though.

My buddy has come up with a shrink wrapped lump containing 'things electronic' that power a warning light without too much smoke.
