Lots of fuel fumes in the garage….no leaks anywhere that Ive found. Brand new tank with hose vapor line from top of filler neck down thru trunk floor into the frame…. ( i think thats correct?)
 
I'm betting on a leak somewhere else. They can be hard to find sometimes. I found mine by accident after months of fuel odor. My leak was at the fuel pump connection but would only leak at higher RPMs. Could never get it to leak at idle.

My car is fuel injected, with fuel pump in the tank…. Ive been under the car tracing length of the fuel line with no signs of leaks:BangHead:

My garage is not insulated, and I live in California with temperate weather. That said, on hot days, the temperature swings from 90F in the garage to 60F at night. This is enough to cause my 1970 car to emit fumes, and I'm pretty sure there are no obvious leaks. Newer cars have a charcoal cannister to manage those fumes, but not older ones.

Do you have those temperature swings where your car is stored? How bad are the fumes? If they seem pretty bad, you may have a leak. I presume you've checked other obvious sources, like the gas can in the corner for the lawn mower?

All good points…. In CT, sometimes spring and fall big temp swings. Not recently yet. Lawn mowers gas cans out in shed.
No leaks that i can find…
But thanks
 
Check the top of the tank at the sending unit gasket. They can weep but not enough to drip as it rides across the seam of the tank. Make sure the (2) vents are not crossed. My aftermarket tank had the positions switched and I hooked up short to short and long to long unknowingly. It would spit fuel above 3/4 tank. The vents should be short to long and long to short. It doesn’t matter which end; car side or tank side.
 
another test is to take the car outside to ventilate for a few hours, with the windows, hood and trunk open. open the garage to vent. Once it's all vented, put the car away (maybe without running, if possible), and begin checking every hour or so. sniff around. if there is a leak, you can tell where the smell is strongest.

for example, if you found the fumes start under the car in the rear, or in the trunk, you're getting closer to finding the source.

The gas fumes have to go somewhere. also true in newer cars, but the charcoal cannister takes care of that.

Top of tank @ sending unit bone dry….
2 vents? As mentioned, i have in tank fuel pump, no return. I’m aware of the vent from near top of fuel filler, down thru trunk… only have that one. I don’t remember, but think there’s a tube on the sender area that has a hose capped with a bolt in it with clamp? Its been a while since I’ve been under there…
 
I live in CA and had the same problem with my Satellite when parked in the garage after a drive. Some of it is carb bowl fuel boiling, but some of it was rear wheel well fuel vent related. I installed this II Much Fuel Vapor filter mounted in the trunk and it works great. Much less smell. $200 and change.
