Hello I am looking at buying this it is only $16.79 on eBay do you think there is a way for me to hook it up on my 49cc TaoTao? If so help would be very much appreciated thanks!!.  Bashan, JR, Alleyoop, Bashan, JR, Alleyoop,

Depending on the size of that gold sensor the only place that might work would be on the drain plug on the cvt side of the motor case.

The size of the oil drain plug is M12 x 1.5

Is it a "pressure" gauge or a "temp" gauge, because your post says "pressure" and the item says "Temp"

[cyborg]

that would be a temp gauge

[themopedman]

Yea It is a TEMP gauge sorry.

[Alleyoop]

I changed it from pressure to temp

[jjoshua20213]

Pressure gauge would be cool though

I have that very same gauge installed on my scooter; a TAOTAO ATM-50 A1. It works great. I ordered a set of adapters from amazon to install the temp. probe in the drain plug mentioned above. Just make sure to use teflon tape when installing the adapter and the probe, or they will leak.

Here's a few pics of it installed:





Just a note, the temperature reading will vary depending on the battery voltage, meaning it might read one temperature while riding and having the battery charged at 14.5 volts, and read another temperature after the engine has been turned off for a little while.

Hey glavey.....I might suggest that the reason your gauge is fluctuating is the teflon tape.....it screws up the necessary ground. VDO sender instructions state in bold letters..Do not use teflon tape on threads. Mine doesn't leak a drop, and doesn't fluctuate either.....I use a nylon washer on the sender, and replace it with a new one every 3rd or so oil change.

I tested the resistance between a 4-way fitting and the outside of the probe with teflon tape put on the threads on the probe; there was no resistance. I even went overboard and instead of doing the usual 1 1/2 wraps of tape, I did 10 just to see of there was any noticeable resistance. Nope, none.

The voltage drop I am getting is from me Frankensteining my charging system and adding an oil cooler with a pump. The voltage from the battery has to go through 2 large load resistors, an oil/fuel pump, and a volt meter before getting to the oil temperature probe. By that time, the battery voltage can be down to 11 volts or as high as 13.8. Seeing as how these gauges are probably designed and calibrated with having around 12 volts as a supply, it is understandable that the reading would fluctuate.
