I'll second some of the comments here. The *problem* is that even a lot of experienced mechanics overlook some of the hoses when replacing "all" of them. Some of the little hoses on the top of my RH tank were hopeless, even tho "all" of the hoses had been replaced. And, yes, be sure to check that big fat one on the filler neck. | ||

...and the hoses on the top of the LH 308 fuel tank:  | ||

Anthony -- "overflow" is perhaps not the best translation, but there is a (normally non-wetted) fuel vapor recovery/pressure equalization system that has a bunch of rubber hoses connecting the top of the fuel tanks and fuel/vapor separator (located tucked-up in the RH C-pillar):  You've probably got a cracked rubber line somewhere in this system so fuel sloshed out with full tanks under side acceleration. The first time I jacked up my ex-308's LH side with full tanks fuel came pouring out the hoses on the top of the RH fuel tank. Bottom line is that you need to inspect (and probably refresh) all of the rubber hoses connected to the top of both fuel tanks. | ||

...hi, thanks so far...I did not get a chance to look at the car today in detail - does anyone know where (if any)the overflow pipe is located? | ||

The guy in the tom yang story is a close friend of mine (he shall remain nameless here too). He had to re-wire the entire car with the help of tom's mechanic. Luckly the fire didn't effect the paint job. But even today, the car is far from perfect. | ||

Check all fuel hoses carefully. On my previous 78 308 GTS, I had ALL of the fuel related hoses replaced and the hose between the fuel filler neck and left tank was VERY rotted, and about to start leaking....Not safe is right! Any gas leak is reason to take the car back immediately and have diagnosed. Go to www.tomyang.net and look for "ferrari stories" and "roasting a 308" to learn of another fuel filler neck hose leak that did not turn out so good.... | ||

Be very careful! My friend has a 78 308 gts and had a fire! The reason was the filler neck line. It was dried out and cracked resulting in fuel dripping on a hot engine. You know the rest... When I got my 85 qv, I had the mechanic replace the line just to be safe for my car was a garage queen. | ||

thanks so far - I'll recheck the filler neck - where does the overflow dispense of the excess fuel? sounds like a poor/dangerous location | ||

if the hose from the filler neck to the tank leaks will likely notice drips when fueling as well - happened on mine. | ||

I would inspect the hose from the filler neck to the tank for leaks. I don't think the "stripe" in the exhaust has anything to do with it. I highly doubt that you are getting raw fuel dripping out of your exhaust. Good luck. | ||

There is an overflow on the left side | ||

Hi, Today I drove my recently acquired '76 308 back from my mechanic who just checked out my mixtures (and who raves about how strong mechanically the car is). This sounds odd, so bear with me - some facts: 1. The car runs as strong as new with great compression. 2. All fuel hoses were just changed (5 months ago) on this car. Here is what my friend and I observed om the way home from the shop today (he was following behind me in his car): After filling the fuel tank (topped it off until pump clicked) I noticed a smell of gas in the cabin - I naturally thought it was me as I had just gotten some on my hands. During a sharp right-hand-turn on-ramp, my friend noticed some liquid spewing out of my left hand tailpipe region - he immediately notified me(we were in contact with each other via handheld radios) but I wrote it off as being from condensation as the car was not completely up to temp and he did not notice any steam or smoke. at this time, I smelled a stronger odor of gas, especially after making the turn. This event happened again during the next right hand turn, and again my friend just observed liquid with little smoke - he also smelled gas from inside his car. I immediately pulled over and shut down. The engine bay itself did not smell of fuel (only the cabin). I could not see anything leaking anywhere. I figured that no way would fuel be pouring from the exhaust as it would vaporize or catch fire first. But, the left tail pipe had a whitish stripe inside - as if something did indeed run out of it. Again, no leaks could be seen and the car was runnning better than excellent, all gauges "in the green". After a while (after some fuel was used), this event did not happen again - my friend was watching me like a hawk. I made other turns and no liquid could be seen. Although, I still smelled gas during turns. My questions are: Could I have overfilled the tanks and during a right hand turn, fuel was sloshing into the left tank and overflowing somehow? Is there a overflow tube somewhere and my friend could have mistaken it to be coming from my exhaust (but there was a tell tale sign, the stripe, in the exhaust that indicated something had ran out of it)? How could it be possible for fuel to run out of an exhaust in a stream like my friend observed? Of all the wierd problems I have heard, this one takes it...... Thank you in advance, Anthony |
