car is 92 accord. I have constant gas smell inside cabin. In morning when i open the car i can smell the gas. It would be great if someone can help me with possible causes.

Done so far.

1. Filler Neck
Inspected Filler Neck. Had some RUST inside and outside. But approximately six inches in length only. I scratched with sand paper to make sure there was no leak. Filled the complete pipe to observe leaks or seepage but nothing.

2. Checked Pipes for leaks but none.
3. Two way valve has one connection going to something connected to center but the next point which should goto EVAP Canister is left Open. Canister was removed. Should I block the Pipe ? Should i leave it or block it ?


Any Other thing i should look at? if it was fuel line leak then the pressure due to fuel pump should make drops fall on ground but nothing. This is really making me nuts.

If you open windows more smell comes inside.
