Assuming the tank already has a cut-out for the float sender, all you need is the sender, the gauge, a bit of wire, and a wiring schematic. Should be pretty straightforward.

I used one of these.
 

I used one of these. Resetable and a lot of information. Very easy installation.

I guess I was not clear on my original message, I am looking to install a dash mounted fuel level gauge for my GAS powered golf cart. The purpose of my post was to see if I could get a photo of another 2017 EFI yamaha cart that had an after marker fuel level sender installed in the gas tank. There was no info on youtube and other sources I searched on. I have found what I believe is a suitable fuel level sender unit and the associated fuel level gauge, I just was looking for confirmation of the location before purchasing the parts and cutting into the gas tank.

My understanding is that dash mounted fuel gauges are "standard" on carts originally sold to licensed dealers and carts sold/leased to courses and others are usually delivered with a mechanical gauge attached to the gas tank cap. If you bought second hand or from a rebuilder, and if there is no dash gauge, the odds are that your cart began life as a rental or in a course fleet.

My fuel level sender, mounting hardware, and gauge just came in, i will be testing the components soon and then installing.

Please be careful. This forum needs you to hang around a bit longer!
