Replacing sending unit- how low does the tank need to be???

"Wish i had a downstairs garage.
But my house would stink of all the automotive stuff. Wife would be so upset."


No you don't.....I have one too below in my house (cape cod) and that is the problem with them....all the fumes of "working on the car" go right upstairs into the house.....not too mention that when you start them up all the fumes go right upstairs.....so I have to start them up and run them right outside to let them warm up....just a pain in the ***.....better off with a detached garage.....The only advantages to a garage under the house is less chance of theft and also going right into your car from your warm house is nice in the winter
