Fuel smell in trunk. Still !!!! - Page 2

It looks like there is a rollover/spill valve already it's the red thingy on the bottom of your black hose. I always put them in a tank install and vent them somewhere outside the car/trunk. A fender well works good. I'm also using a compressed air muffler as a breather cap after the valve to let air in and fuel out without being open. They work well.

Mickmate,
The point is to 'vent the tank, the rollover valve is a bonus.

The two components (vent and rollover spill valve) are typically combined in one unit. The tank needs to be vented so it can let fuel out without causing a vacuum or collapse of the tank as fuel is pumped out. If the tank isn't vented the car won't run for long. The trick is to vent it without fumes. Rollover spill valve stops fuel running out in the unfortunate circumstances the tank and car are upside down.

mickmate,
Exactly, only the vent valve should be located in the tank it self. Maybe I just read your other post wrong. Remember CR uses a side fill and actually to fill the tank the fuel has to rise ABOVE the filler tube by at least 4 inches! NOT the best design, but then again.

Whatever, the tank, any tank, needs to be vented properly.

Side fill can work if they are vented properly though as you said not the best. The vents I put in are at the highest point of the tank on the opposite side to the fill.

Try that.

Wow! Pricey but I'll bet that does do the job. Same as the one I posted but very hi-tech. That is a splash/spill proof combination valve. Pretty cool.........trying to see if it will post here so everyone can see.....

My cars been on the road for 25 years and for all that time my trunk has smelled of fuel. I was worried about it at first but now it is like an old friend, when I open the trunk it's there. Not sure I would want to sneak into a drive-in, oh yea, whats a drive-in. By the way Rbray, your trunk looks great.

It's a $26 part with a $3 end on it??

Tonight I was taking a closer look at my fuel lines and I found some cracking.
Looks like it’s time to replace all of the rubber fuel lines in my car.

thanks again everyone for your help.
I'll keep y'all posted on my progress.

That would be the source of your vapor leak. Keep us poster after changing them.

Yesterday I replaced the old SAE 30R7 fuel hose in the trunk and replaced it with SAE 30R9.
I ran the fuel pump for a few minutes to check for leaks and then closed the lid for the night.
Guess what? This morning there was no trace of a gasoline odor !!!

Thanks again to everyone.

Mystery Gas/Fuel Odor Problem- SOLVED !! Hey everyone- I had to share regardless...
I am the proud owner of CSX-4970 427 S/C (also own 05 Ford GT). Since buying my wonderful machine last summer I began noticing a mystery odor of gas in the garage, even after a few hours of storage. I did all the research I could, checked all connections possible etc and no sign of a fuel leak anywhere. I brought the car to the local "high-end exotics dealer/mechanic" for some advice/repairs and was given a misguided diagnosis and grossly ripped off. Smell and obvious fire/explosion hazard still very much there- not even an improvement.
I then luckily heard through my car-guy network that there is a MAJOR problem with the ethanol infused pump gas being forced down our throats... Especially in metropolitan areas of the country.. It seems the ethanol alcohol being put into our gas literally eats through the rubber fuel lines of our cars, causing no actual "leaks", but allowing fuel vapors to permeate the rubber and accumulate in any confined area- like a garage... And obviously the stainless steel braiding around the rubber does not help the problem. Unfortunately, nor does the TEFLON insulated fuel lines.. They keep the problem at bay a few weeks longer but they too succumb to the ethanol eating through them...
I called the good folks at Aeroquip and they honestly and confirmed all of the above.. I asked the Aeroquip rep,
".. then what do I do to solve this potentially dangerous problem?".. He said, ".. Replace the SS braided fuel lines with Aluminum hard lines, preferably 1/2". ... I did so and PROBLEM SOLVED... what a relief... Hope this is useful.. Best to all.. Cobra Kurt...
