Hi,

Okay - I replaced all my evap lines - all fuel lines are new also, including the filler hose.

After I fill my tanks, I smell a strong gas odor when I get back in the car. After a few minutes the odor goes away.
I am not spilling any fuel at all when I fill up.

I thought it might be normal due to the proximity of the filler to the driver's back and also the vapors escaping from the gas pump nozzle to the atmosphere which may settle in the driver's sde area.

Does anyone else experience this after refueling? Is this normal?

I would think not.

I don't smell any gas after I fill up. The only fuel oder I smell is after I park it in the garage. The Fume Recover system on my car is not 100% so some of the fumes simply leak out.

Do you leave your car door open, or window open when you fuel up? The fuel filler neck to the driver side tank is a common source of leaks.

I could smell gas after shutdo

I could smell gas after shutdown on my previous carb 308...I tracked it down to right at the air intake on the passenger side. Was quite obnoxious in my garage.

I had all the vapor recovery stuff removed by my mechanic, based on his recommendation...probably was not a good idea in hindsight....but I no longer have the car.

All vapor recov. equipment is

All vapor recov. equipment is in place and all hoses are new and were inspected. Other than a hole in my tank (no leaks though - top of tank?), I can not think of anything left! If I had a hole, I would smell gas in the garage - I literally put my nose all over each tank and can not smell anything!

Thanks,

Anthony

Smell the air intake on the passenger side, right after shutting down the engine....

The air intake smells a little

The air intake smells a little - but I would expect this - you're essentially smelling right down the carb throats.

After taking the airbox off, one can smell a little fuel also.

My problem is I smell heavy raw, fuel after fueling up , no matter how much I put in.

I think the next step is to pressurize my system to 2 psi or so - pressure should be held indefinitely......this is really annoying!!

Thank you,

Anthony

I found a similar baffling sit

I found a similar baffling situation on a 308 I was working on last year. It turned out to be a very small crack in one of the vent lines coming out of the passenger side tanks. No doubt a vibration crack caused by years of use(1979 308).
Easier to patch than to find, as only wiggling the line showed the small leak.

Anthony:
Do you think one of the Evaporator hose nipples coming out of the tank could have been cracked during replacement of the Evap hoses? The nipples are very thin walled tubing.

You guys reminded me that I&#3

You guys reminded me that I've seen a few cracked vent tubes on the tops of the right hand tank over the years...and like Matt mentions they were all a bear to find. Which reminds me that there is a Fuel System Dye Penetrant availible that is poured into the gas tank and leaves a visible trail where ever there is a leak. It's harmless to the engine or any of it's components.
