Raw gas smell when driving?

Hi All,

Took a 40 minute drive the other day , all highway at about 65 MPH and noticed the car had surges of strong raw gas smells that would come and go?

Would last about 30 seconds and then go away...10 minutes later would come again? Any ideas? Guessing carb may be on the blink?

thanks
Joe

Check your gas cap.... Also check and smell your oil at the dipstick for gas..

Re: Raw gas smell when driving?

Gas smell coming from front of cab or from back of cab? From front, check your fuel lines to and from fuel pump to carb. If from rear, then your burning way rich which could be a dirty air filter, bad plug (s) that are fowling jets that are too big or your floats need adjusting as your braking and the fuel is sloshing forward and dumping in causing a rich factor and going out as unburnt fuel.

Raw gas smell was from inside the car while driving- on highway. Would be a surge smell and then go away and then come back a few minutes later no braking while occurring...thinking of just swapping the carb out.

thanks

Re: Raw gas smell when driving?

Do you still hav the charcoal caster under the hood?Do you still have the large vacum hose that T's off the PCV valve hooked to the caister along with all the other hoses?If you have the canster but not all the hoses,the chances are you are getting fuel vapor escaping out of the recovery system.Either remove the canister and plug ALL the lines and find a way to vent your gas tank elsewhere,or hookup all the hoes.

Surging= incorrect ignition timing. period.
Incorrect timing, and ignition curves will cause all kinds of problems at speed.

yes I do have a rubber fuel line from the fuel pump to the carb, is that a problem? Rubber line is new.
