Just started noticing a fuel smell in the interior of 1990 civic a few days ago..
The smell is coming from the rear seat area behind the drivers side.
I had the rear interior taken apart, check filler neck, checked all fuel lines,
did a pressure test etc etc etc.. There's no leak ..
Spent a few hours on it.
So the mechanic buddy at my dealer told me that it could be a small small hole on the gas tank itself or a seal on the gas tank letting in fumes inside the car..

Should I just replace the tank (and fuel pump whle at it) ??

any ideas ?

 

I know a read a thread about this same problem a few days ago but i cant seem to find it.

Turned out when the guy dropped the tank he found a hole the size of a screw. Seems a previous owner screwed his sub box in and nailed the tank. You mite have the same problem, or maybe the tank just rotted a bit.

And yeah if you go through the trouble of dropping the tank you should replace the fuel pump while you have it apart, its probably the original one.

 

no bueno

I recently screwed down my sub box ! I think this is the problem !

 

my 90 seems to have the same problem for the last six months or so but i cant find no leaks niether...its just when i add gas though.... sucks

 

So we found out today there was a screw hole drilled through the top of the tank,
(courtesy of yours truly).. ops: ops:
I guess this happened when I replaced my rear trunk mat and removed the subwoofer box and reinstalled it and drilled/mounted it to the floor.
So I installed a new tank, and replaced the fuel filter while at it.

Of note: The old tank had so much dirt/buildup when we drained the tank.
We poured it into a bucket and the dirt settled to the bottom.

Lesson 1, never drill a subwoofer box to the floor of your trank/hatch. LoL

lol I remember that thread too, kinda funny how it actually ended up being the problem here too!

 

Post Deleted: Didn't read that OP had fixed it...damn those long screws.

Too bad you had to learn the hardway too! I'm just glad I can't take the blame for drilling the hole.
