Fuel smell after a hard pull

[Frankycheechoo]

I noticed lately after a hard pull I get a gas smell in the car pretty strong . Anyone have this issues ? Cobra is basic bolt on and tune .

Have you done ANY fuel related work lately? Including just pulling the injectors or disconnecting a line for other maintenance or upgrades?

What he said.

If you haven’t done work, you’ve likely got a leak starting that is showing up after a pull due to higher pressure.

First place I’d look is around the rails and injectors.

I haven’t done any fuel work. Engine hasn’t been tinkered with .
I check fuel rails they seem dry and I don’t smell any fuel around there .
What should I be looking for?

Evap lines. I'd look at the one that comes off the valve in the passenger fender well first. They tend to rot.

Not sure but you should have a code of Evap is leaking.

The “after a pull” thing makes me thing it’s fuel related

Yes there should be a code but I didn't have one when my hose from that same valve split.

Not surprised. PCM on these cars is still “dumb”

Fuel smells can be a total bitch to track down because of how fast it evaporates.

Have you checked your fuel line that connects to the rail? I've heard of the o-rings going bad once.

Check the FRPS, the o-ring may have gone bad.

The only other thing I can think of is injector o-rings.

I’ve had a few people say could be tuning a little rich check with tuner .
Don’t know these things happen all of sudden if car is tuned and drives normal then out of the blue the tune is set off .

Check to see if you have a leaking injector o ring. Recently happened to me. Was a good excuse to buy new 60’s for my car. Turns out I needed them anyway, but that’s a different story in my build process.

On second thought, mine leaked upon startup and idle, had nothing to do with WOT or anything, but worth a look.
