Any solutions to prevent garage from reeking of gas from carbs?

[RSBob]

Things mom never told you: Son When you park a car with Webbers in your garage, fuel will evaporate from the float bowls making your garage reek, create a potentially explosive situation and be bad for your health. It may also make your wife very unhappy. This is especially true for an attached garage with a pet door into the house where fumes enter the house.

I have a three car garage and parked the offender in the far stall and installed next to it a high velocity fan which draws some of the fumes outside. This fan runs 24x7 continuously which does no favor to my power bills.

Has anyone solved this issue other than ( trying to beat the deadbeat responses) selling the car, changing to another induction system, or parking it outside? Is there an effective way to cap the stacks or some other solution? I doubt tennis balls would do much good at sealing.

Hayulp!

The only thought I have is creating a tin shroud which will go over the carbs with a 3” hose attached at the top which goes to my exhaust fan which I will have to step over all the time.

Today’sfuels are partially to blame as they have a higher Reid vapor pressure, so evaporate more easily than the gasoline back in the day. Manifold heat isolator help somewhat but not that much. I installed switches so I can turn my fuel pump off a block or two before parking the car and then let it idle a bit to lower the fuel level in the float bowls. Unfortunately, short of hooking up a hose as you suggested, I think that’s about all you can do.

Like Jack said, shut off the fuel pump and run the carbs dry.

My '83 with PMO's isn't that bad - don't get me wrong, you can smell fuel, but I'm reasonably certain if I vented (exhaust fan) the garage, it wouldn't be very noticeable.

Are you sure it's just the carbs causing the fuel odor? My car stunk of fuel really bad for quite a while and I traced it to the fuel tank vent lines:

Fuel Smell / Odor - Replaced Gas Tank Vent Lines / Hose - 83SC

Considerably better since I replaced the lines.

Good luck, Gordo

It’s worth a shot. Where did you find them?

Keep in mind that one of the issues with modern gasoline is that the fuel actually permeates through most rubber fuel line because of the ethanol. Wipe the fuel lines and make sure they don't smell of gasoline.

The only solution for this is to use a fuel line that is ethanol safe like any PTFE hose, AC Delco Greenshield or Earl's Vapor Guard.

I recently installed brand new AN6 stainless steel braided fuel lines and had this issue. No leaks but there was a strong odor that came out of the tunnel (no fittings within) where I pulled the lines thru. I replaced those lines with teflon lined versions from BAT Inc./Mocal, who also helped me with some tough to find fittings and crimped on the fittings on one end. No odor so far (knock on wood).

Smell is definitely from carbs the rest of the smells fine. I need to know about those caps. Seeing several double cojoined ones for 4 cylinders.

A great idea. I live up a long hill with a steep driveway so timing would have to be spot on.

Because he can.

[RSBob]

If you really need to know, This question is regarding my 914 3.0 with Webers. The Other thread is regarding my 911 which doesn’t have the issue or Webers

air filtration system/and or air circ system

You’d have to also cap off the vent tubes from the carbs besides covering the throats to cut down on the smell. Making sure the fuel lines and evaporative emission system is connected and functioning properly.

[john walker's workshop]

Buy 3 pairs of caps and separate them. Cap the vents too, as mentioned. Redline Weber or Pierce Manifolds.

[fanaudical]

As far as caps go, you can purchase through McMaster Carr:

I think There was a set of six covers for Weber 40's for sale in the classified section. Maybe a couple of weeks back. Not sure if they sold, but worth a shot.

Run 110 leaded to remove that crap gas smell.
