Strong gasoline smell in the cockpit of 356C
Hi, I am trying to find the source of the strong fuel smell in the cockpit, particularly noticable after refillin the tank, but can be at other times too. Carb/pump ok, and with a C the fuel cock is under the tank, not in the cabin. Any ideas would be appreciated (Mrs S is going off the car!)
Thanks, Bill

There is a tiny section of fuel hose under the toe boards in the center of the footwell that rots and leaks.

Check the system from the fill up to the short hose in the tunnel CJ referred to. Any leaks your nose will pick up on.

It's the cork gasket under the sender if it happens after a refuel.

Re: Strong gasoline smell in the cockpit of 356C
Start by checking the seal on your gas cap. With a full tank gas can easily slosh up there during spirited driving.

Thank you all, particularly CJ Murray, the hose was rotten - really made a mess of the sounddeadening material on the floor. Can only get better from here!C J Murray wrote:There is a tiny section of fuel hose under the toe boards in the center of the footwell that rots and leaks.
Also the green wire is going to be re routed!

Glad to help.
Take a look at the other suggestions as well. Our cars are old and multiple problems are not unusual.

Old hose doesn't like new gas with ETOH. Replace with newer ETOH safe hose and do the same with all hose sections at the same time, including the short piece from petcock to metal tube by front firewall and section of hose behind fan housing which is at times overlooked.

Re: Strong gasoline smell in the cockpit of 356C
Looks like you found the problem Bill, but I have had fuel smells in my C coupes in the past, even with good fuel lines and cork tank gaskets in place. A freshly filled tank will release some fumes through the tank vent into the trunk and then get picked up by the fresh air system, especially if spirited driving happens on a full tank. After awhile the fumes go away as the gas level drops. When filling, I am leery about the auto-shutoff of the fuel nozzle. I fill slowly and at the first click off, stop filling. No 'topping off'. Otherwise overfilling may occur, potentially leading to more fuel smell in the cockpit.Bill Scholfield wrote:Hi, I am trying to find the source of the strong fuel smell in the cockpit, particularly noticable after refillin the tank, but can be at other times too.

Tank vent has a line to RF fender well on T6B and C. Doubt fuel smell would enter fresh air source. Fuel level sender's gasket will cause smell in interior though.

I stand corrected, Thanks Doug! Yes, it doesn't make sense to intentionally vent the fuel tank into the fresh air system.Doug McDonnell wrote:Tank vent has a line to RF fender well on T6B and C.

But if the vent line is missing it could happen. Made one for someone missing the vent line.
