Gas smell in cab

[rsgt]

My truck smelled like gas in there real bad when I got it. I replaced the sender ,it did not work. I replaced all the rubber hoses with fuel injection hoses which are suppose to be more vapor resistant and clamps. Now there is not a hint of gas smell at all.

I don't recall having ANY rubber parts in my truck; there are not vent lines because it's a 2500, but otherwise it's a steel tube coming out of the sender, which then goes down and passes through a grommet on the floor. It then (outside, below the cab) transitions to rubber for a fuel inches before connecting back up to steel.

So, no rubber hose in my cab at all. This pic is from before the restoration, but it stayed the same.

Yes my unit looks exactly like this.

That's exactly what I think when I top it off. I gotta change the sender gasket and filler neck gasket, I only smell gas when I fill all the way up. Otherwise, no smell at all.

Yeah... that's about where I'm at with mine. Hence I have searched for a solution. I removed the sending unit to check the float, etc as my gauge won't go past half full. No change. Then came the smell. So I believe I'll replace unit and gasket.

A big THANK YOU to everyone who contributed to this. It was really a lot of help!

If you dont get that gasket seated just right it will vent or leak. Probably just pulling it out again and reinstalling it will do the trick. I had that on a 67 many years ago. went and got fuel then drove around a corner. I smelt gas and looked down and saw fuel running across the floor. Needless to say it became a non smoking flight coming home.

You more than likely have a gas cap that only vents into the tank, it builds pressure from fuel vapors which in turn seep into your cab. You can test this by sucking and blowing on the cap. You need one that vents both ways and a new sender gasket.

When installing gasket and the locking ring use a non sparking tool (brass drift) to make sure it goes all the way home. A little Vaseline helps the rubber donut seal properly too!

I had a leak this past summer, was leaking at the fitting,tried to tighten still leaked,when I get back to the garage, going to remove the flare nut and go with some fuel injection fuel line and clamps,hopfully no more smell/ leak
