I usually park my 87 Weber'd GL with the nose uphill on my sort of steep driveway. Last night I backed in and parked with the nose down. It poured rain all night (kind of rare here in Durango) and when I encountered it this morning there was a trail of gas down the driveway through the water. Inside, the driver's foot well was soaked with gas and water.

 

I popped the hood and checked out the vent line and return line. I couldn't tell if it was condensate or a dropp of gas on one of them but the area looked like it had gas on it that had evaporated.

 

This gas smell is a reoccurring problem, but I haven't seen signs of it in a few months until now. I could never figure out what it was. The rear vapor canister is fine. I only have the supply fuel line running to the Weber, no other lines.

 

Maybe I'll try to hook up the return and vent to the Weber and see if this problem goes away. Any ideas?

HMMMM....

 

Start with the fuel tank and check all lines, grommets, connections and hoses for leaks, cracking, or rubbing on moving parts. Start tracing it back to the front and be thourough:brow:

 

Here's a link that someone was having troubles similar to yours.

Kinda sounds like you have a water leak around a window if there is water on the floorboards? Follow your nose, it's the best thing to track down the leak

the fuel lines run down behind the dash to the rocker sills and then to under the back seat. they are inside the car, behind the plastic shroud under the carpet. perhaps there is some rust? parhaps there is fuel being pushed out or gravity siphoned up the vent line.

 

Is the fuel cap on?

 

Interesting and odd circumstance, i would say its coincidental with the rain being so severe, and a pre-existing fuel leak.

Miles - I'd say it's coincidental, too. Fuel cap is on, and new, but the vent line is uncapped, so the tank is breathing, anyways. I had the same thought that a siphon occurred to pull the gas out while the vent was near the same level as the tank.

 

My fuel gauge was around 1/8 when I parked it and it read just above E when I found it in the morning.

 

I still think that I should hook up the return line and the vent to the proper spots on the Weber and watch for more problems.

 

I'll also do a check for rust, etc... You say the lines run inside the cabin under plastic retainers? I assume this is on the drivers side.
