1995 Caravan, 3.0 Strong Fuel Smell?
Hi,
I have a 95 Caravan with the Mitsu 3.0. For the last week or so, I've noticed a very strong fuel smell. I only drive this car back and forth to work, about three miles one way. The odor is very strong by thr time I reach work. There is no power loss. I've noticed a serious drop in fuel economy. The odor is strongest under the hood. I can't see any issue (fuel leak) under thr hood. This problem started abruptly.
Any ideas??
Thanks, ahead of time!

A leak will leave wetness behind for a brief time. A stain may be left after it evaporates.
The fuel line is pressurized from the tank going forward.
A cracked or disconnected rubber evaporative emission hose will make a fuel odor with no wetness, but won't really affect fuel economy.
If you only smell the fuel odor after driving, it is likely a pressurized line/hose, fitting or seal.
If you pull the vacuum hose off of the rail-mounted fuel pressure regulator and fuel comes out, the regulator has failed.
It is important to find this before driving the vehicle any further as it is a fire hazard.

Check from the tank forward, everywhere. I just found the source of a faint fuel smell after driving - the rigid line by the RR wheelwell in my Daytona has dissolved undercoating. If it weren't undercoated, I might not have located it easily, as it doesn't yet drip on the ground. But I parked the car until I can fix it.

Found the leak. Had a rusted through clamp on the hose just after the fuel filter. New clamp, all fixed. Glad it was such a cheap easy fix, as I'm in the process of buying a new Challenger and will be selling off the 95 Caravan.
