Gasoline smell
I have a 95 xlt 4wd with both tanks functional and accurate gauges which I'm pretty happy with so far.
I parked her in my garage about a month ago right after I filled both tanks with ethanol free gas. When I went back in to grab something a few days ago, I noticed a strong gasoline smell that fills the whole garage (5 bay)
I crawled underneath to take a look and there is no sign of leaking gas anywhere that I can find.
Is there likely places that I should start really digging into to see what is going on?
I don't drive this truck often. It's occasional use only. It could stink like that everytime I fill up or just all the time, I'm really not sure. Since the last time I parked her, the only change I've made is that I insulated and sealed up that whole garage and installed a pellet stove. So the smell could just be a lot more noticeable now.
Any insights would be helpful.
Thanks!

How long have you owned the truck? Does it produce the same mpg on both tanks?
How full did you make the tanks? Did you stop when the pump shutoff the first time or did you fill them all the way up the neck?

My bet would be on a bad purge/vent valve on one of the tanks, that's allowing pressure to build in the tank. Or possibly, somebody put a vented fuel cap on one of the tanks, IIRC, the EFI trucks should be using non-vented fuel caps.

My rear tank developed pin holes in the top of the tank from rust. Smelled faintly of gas frequently for about a year, but could never isolate it until it started to dribble after getting sloshed around and left a trail.
Replaced both tanks, FDM"s, level senders, vents, and all the rubber hoses in one shot, so I hopefully will not have to mess with it again.

Is it hard to start after sitting, you could put a fuel pressure gauge on it, start it let idle a couple minutes, turn off, then watch gauge pressure, for 5 minutes, and record pressure, every minute, see how quick/slow pressure goes down, could have leaky injector/s.
