gas sender

[chainsaw]

I'm replaceing the tank sending unit in the 65, I think I have 1/4 to 1/2 tank of gas. Question is how much gas (if any) will flow out of the line from the engine to tank and sending unit when I disconnect it ? Thanks.

If you have only a quarter tank no gas should come out, not sure about the half way point thou, you should also use a long ground strap and keep it grounded while you are removing the sending unit out as not to generate any static electricity....same with install..

If you have the in cab gas tank I don't think any will come out.

When I removed the sending unit from my truck the only gas that I got in my cab was what dripped off the float.

I think it's because the connector for the fuel pick-up on the sending unit is on the top of the tank; fuel can't siphon out if the end of the pipe is above the level of the fuel in the tank.

Thanks guys, I didn't want to flood my cab.

Be sure to keep your windows open. Just b/c no liquid gas gets in your cab doesn't mean its safe. Fumes will still be escaping from the sender hole.

changing the sending unit in the cab is pretty easy. As said above "only gas that I got in my cab was what dripped off the float"
Last time I changed mine was on my lunch our at work. took about 10-15 mins. I kept my doors open.

Might be a good idea to disconnect your battery. just a thought. I dont believe I disconnected mine when i did it though.
