...to be getting a fairly strong fuel smell in the frunk? I can smell it pretty good in the garage. Having the car inspected Friday but just wondering if this is typical. Thanks!

some times its simple... a bad gasket at the filler neck

or sometimes a hose under the tank (do you know when those were last replaced?... I like to change mine out every 5-6 years)

sometimes its a pin hole in the tank itself... they tend to rust through from the inside, often where the soft pads are that the tank mounts on.

If you had just filled it... and maybe overfilled it to the very top... they can smell a little due to being overfilled.

Ditto. Mine was a rust hole behind the carpet/pad that manifested itself when I filled up the tank...and it ended up pouring onto the garage floor.

Replace all rubber fuel lines so you know they are all new, and use ethanol hose!

Service records show fuel tank, sender & fluid...along with all hoses were replaced in 2009 - 4,000 miles ago. Sounds like those hoses should be replaced, at a minimum...

Be very careful if you have a gas hot water heater or other open flame in the garage. The fumes can ignite. Heard about a guy draining the gas tank of his newly restored Camaro in a closed garage and the whole place blew up.

Yes that would be a good idea,filler neck gasket as mentioned and don't forget the gas cap seal there are 2 types year dependant,if you have the plastic cap don't buy the cardboard seal like I bought from Pelican....pretty much useless after a while.
914rubber should all or most of the parts you need,good luck.

It's concerning when you get that strong gas smell in the garage. When I bought my car it of course had Webers on it- no gas leaks. Despite that, my wife complained about the gas smell. Now with the Motronic injection you smell nothing. Much better:).

Despite the cars being the same, she never complained about my 2nd Six, Webers again, and parked in the garage. My theory is we were just so used to smelling gasoline in the garage back then- in the mid 80's it never became an issue. I don't know if the gas is a much different blend now and thus much more gas smell or not.

Seconding this. My 914 reeked of gas every time I filled up, or it got warm out. Checked the gas cap and the rubber gasket was completely gone.

as a new owner...
its worth telling you in case you do not know...

the factory fuel lines down the tunnel (feed line and return line) are both a special type of clear vinyl.

pretty robust actually
but they can crack and leak also
you usually smell this because its inside the cockpit area

and VERY GOOD IDEA to also replace these 2 lines
they are OLD.... and PLASTIC... most people find them to be very brittle when they go to remove them.

This describes my current situation. Until finally getting this car back on the road last May, the last time I fueled a 914 was from a leaded gas pump (IMG:style_emoticons/default/blink.gif) I'm still getting the hang of fueling with these skinny unleaded nozzles that drop down in the tank so far. The last refill, I over did the topping off and am paying the price with a stinky frunk (IMG:style_emoticons/default/sad.gif)

I would do it so you know they are new and they are the correct type of hose for the ethanol fuel.
It has been done wrong before, and ethanol eats away at the rubber.

If not that, there is a charcoal venting system, which after 40 years has served its full life span. You can replace the charcoal, google that.
I doubt you can buy a new canister fir a 914.

I would start with easiest, work your way up

1) gas cap gasket
2) rubber fuel lines
3) canister
4) pull the tank out and find the leak

Meanwhile either park it outside or open a window in the garage.

In some cases, the tank has rusted through and has pin holes from the fabric pads where it rests in the chassis. It wont leak until the tank is more than half full.

I'd try the gas cap seal.
