Blower in Garage bringing gas fumes in house
 
Hey all! New user here. I have recently purchased a new "toy", which is to say I now have a VW Beetle in my garage! Because of this and the open-air engine, Gas fumes from the motor are seeping into the garage. This would not be a problem except for the Blower for my HVAC unit is located in the garage as well. (enclosed in a closet, but apparantly not shielded from the fumes as they are leaking in the house now)

So, I'm looking for a good pro tip on how to keep the fumes from seeping into the house via the HVAC without straining my pocketbook (ex. moving the furnace) and keeping my wife happy.

Thanks all in advance for answering my post. I will lurk now to see if I can be of any help to anyone else.

If you are getting fumes then you are getting carbon monoxide. Silent killer. It's not a good idea to run a car for any length of time in a garage. Run a hose from exhaust to the outside and as said seal everything.

Not running the car in the garage. This is due to the open air engine, premium fuel, (can't run ethanol in an engine built in the 60s) and a rich fuel mixture. It's just the fumes of the fuel not the exhaust.

Thanks for the advice about sealing everything. I have called my HVAC buddy and he's gonna stop by the house tonite to check things out!

Seal all connectivity between the main home and the garage as well.

This is a definite health and safety issue and needs to be corrected asap.

Pay to have the furnace moved into the house, or construct a closet that can be entered from within the house for the furnace & water heater. Also, even though you have gypsum on the walls facing the rest of the house, the cracks would not be sealed to stop fumes from entering the house, along with CO. I would look at maybe spray foaming the cavities, then put back up the gypsum, and tape & mud with two coats of mud.
