Short story: Getting pretty strong, random gas odor in the cab of my 2007 Rabbit with 18,000 on it.

No evidence of leak under vehicle and no odor outside the car or in the closed garage. Certainly not losing much but the odor is unmistakable.

Long story: Fuel pump was losing pressure so I replaced it and the filter. CEL came on after a few miles and was told the filter/regulator was pushing much too high pressure. Had filter replaced with another. CEL came on after a few miles and ended up at VW dealership and was told the filter/regulator pushing too high pressure and had filter/regulator replaced again with factory VW part. All has been well for 4000+ miles and now this.

Million to one shot here but - could it have something to do with car sitting in garage with AC and then brought out into near 100 degree temps??????

Thanks

If you smell gas fumes, there is a leak.

If your smelling gas, as in not burned fuel, look under the hood around the injectors,
fuel rail, and fuel line, look for a wet spot.

Check your EVAP and return line at the tank. You could have cracked or broken any
of the lines at the tank when replacing the parts.

Nope - Everything under the hood is dry as a bone.
No evidence of gas "moisture" anywhere around the filter.
No lingering odor inside or around the area where the fuel pump is.

Again, this is intermittent.

Well, you can't have gas fumes without GAS, so there is a leak
somewhere. Can be a leak anywhere along the fuel lines. I have
an HHR, I could smell gas, it was rusted fuel lines. IT got
progressively worse till I could eventually see the puddle of gas
on the ground. It went from fumes, to visibly leaking fuel within
a few months time...

I had a Pointiac Vibe, it was a pre-cat burned gas smell when I came
to a stop, on a down-grade with the blower motor on, any setting.
No matter what GM did, they could not fix it. Every single replacement
still resulted in the same smell. They replaced the exhaust manifold
twice. The smell was coming from the driver side rear corner of the head.
They did everything except replace the head, refused to replace the head
and the smell never went away. Since it went in MORE than three times
with the same results, we actually got Lemon Law cash out of the deal;
the loan was paid off, and they let us keep the Vibe + $3000 cash; COMPANY
car though so I saw not one dime, but kept making me drive it with the fumes...
SO, I beat the living **** out of it....

You can't have fumes without leaking gas unless it's the EVAP system...
Though, EVAP fumes are a little different, it's still gas fumes...

Oh, I forgot about injector seals. Maybe one of your injectors leak, either out
side on the head, or into the chamber(s).

It's a possibility, one or more leak into the cylinder, so when you fire it up, you're
getting fumes from that. Injectors do leak naturally, but with the over pressure
you had, could have damaged one or two injectors.
