I picked one up from NAPA for my boss's truck. I just installed the sender into one of the pressure test ports that was plugged with a 1/4 plug. You can drill a hole in the pan for the sender, but you just might cause a leak if it is not sealed good. I installed the kit on a Chevy with a turbo 350, but I'm sure there would be a pressure test port on a Toyota auto that you could tap into.
