Garage smells with gasoline leak

[ienjoyvws]

Good morning,
Please help if you can. I have a 56 bug sedan, stock 36hp engine and for the past few days when i enter the closed garage where the bug is parked, it smells of a gas leak. I have re-tightened all of the gas lines at the engine and there are no apparent leaks at the fittings or throughout the tubing itself. Nothing seams to be dripping out of the carburetor. I opened the trunk and nothing smells around the gas tank whatsoever. When i open the car door and stick my head in, nothing smells.

What would you suggest?

Thanks very much

I think I may have found the leak. There is a rubber gas supply flex hose behind the rear tire location which appears to connect the rigid steel supply tubing from the gas tank to a short steel tube which goes into the engine compartment and connects to the fuel pump and one end of this rubber tube has wet gas around it.
Inasmuch as the two ends of this rubber tube do not have clamps, they seem to be friction fit, would you try a hose clamp as your first attempt?

They do not need clamps as long as the line is tight on the metal fittings but if it's wet, replace the line.
The ends are probably cracked from age and it's rotting from the inside out.
It will only get worse.

It doesn't hurt to add clamps too. On a new rubber line.

As always THANKS!

Ooops one more question; when i remove this rubber hose to replace it, will all of the gas in the tank want to run out of the open end?

[splitjunkie]

Yes it will. If your car still has a working reserve valve then you can put it in the off position.

Grab yourself some hose pinchers whenever you can.

Yes, if you don't have a reserve valve to turn off, there is a rubber hose up front under the tank that you can crimp.
It's a short line from the tank outlet to metal line on body

Of course that one might be worn out too.

Today's fuel mixtures, ethanol in particular, rot the crap rubber their made of these days (doesn't matter who you got it from, unless it is stated for use alcohol fuel mixtures).. they swell, they shrink, they crack or seep after a season or three...

I can't tell you how many times I've had to remove again & again 12" sections of the best stuff I could find (short of braided high pressure fuel injection line which aint cheap Vs. off the shelf fuel lines on a roll sold by the foot) that ethanol hasn't disintegrated at one time or another...

So if you don't have shut off valve then yes, find whats seeping & pinch it off as needed... but after the fact, pay a few bucks & buy the best rubber lines you can find...
