Fuel smell in cab
Ok, so I just brought home my 71 that's been in storage for the winter.... I've put all of about 200 miles on it since I've owned it, and today, when I opened the door, I got a good wiff of gasoline, and it lingered for a while. It happened again tonight after work, too, but not as strong. The truck sat outside in direct sunlight, and it had about a half tank of gas..... There are no evident leaks, drips, etc., just fumes. What gives?
Oh, it does have the rubber hose on the filler neck..... Maybe the wrong gas cap? |

Re: Fuel smell in cab

Re: Fuel smell in cab
It's just a normal thing when you have a tank in the cab. I've had 5 of these and at one time or another they have all done that.

Re: Fuel smell in cab
It's not normal to have a gas smell in the cab, they wouldn't have sold them that way. You need to follow your filler hoses, fuel lines, and maybe take a look at your tank seams. If you smell it inside your cab, you have a leak somewhere. Most old trucks smell like old upholstery material rather than gasoline.

Re: Fuel smell in cab
Every old truck I have been in (which is a bunch) that has a tank in the cab has had an occasional gas smell. A hot cab from sitting in the sun, a full tank, a clogged vent tube line,a wore out seal or a number of other things can cause it to happen.

Re: Fuel smell in cab

Re: Fuel smell in cab
I don't even fill mine up anymore. I never go over 3/4 of a tank in my truck, I notice that anymore and I get the smell.

Now, who sells the gasket between the sending unit and the tank, without buying the entire sending unit? I checked two places' online cats and didn't see it listed seperately. |

Re: Fuel smell in cab
The relocated tank was the best thing I've done to my truck. It's just nice not to have to worry about it anymore. I was changing seals and fixing lines a plenty in my old tank in the cab, I couldn't hardly drive the truck from the gas smell.

Re: Fuel smell in cab
Thats why I bought my truck. Nothing soothes the soul like gasoline vapors.

Re: Fuel smell in cab
Usually, a new gas cap will fix most gas odors in these trucks. Any parts store that carries Stant brand parts will have one. They're under 10 bucks.

Re: Fuel smell in cab
Any number of places for that smell, but none of them normal or safe.
The seal around the sending unit, the vent line, the gas cap, the fuel line or its fitting, or like in my case, the tank had a pinhole in the welded repair on the bottom of the tank. If none of these are the culprit, see if the fumes are coming in from the carb then through the firewall. Personally, I'm moving my tank to the rear just to avoid all these problems, regain some much neded interior space, and improve the safety factor should the unthinkable ever happen.

Re: Fuel smell in cab
don't forget about a little more traction from the weight in the rear, 21 gallons of gas = 132lbs +or- depending on the grade of gas.

Re: Fuel smell in cab
I chased the gas smell in my cab for six months. Finally replaced the little rubber hose on the filler neck. That was it. Once it was out of the cab I could see it was dry rotted. The crack were really small and no sign of liquid gas seeping out. The crack was just enough to let fumes in the cab. Might try it. Cheap fix.

Re: Fuel smell in cab
Thanks for the info.... I went to the local parts depot today and grabbed new lines for the vent and evap line, and ordered a new sending unit with lock ring, gasket, and the windsock..... One place wanted a 20 dollar order for a 2 dollar sending unit gasket, and another wanted 13 bucks shipping, so I just said fughedaboutit and bought the whole unit..... I figure these gas lines and sending unit prolly lasted 35 years... They've served there purpose, I'm gutting the interior this weekend to do seat, dash, carpet, instruments, etc, so if the new lines last another 35 years, I'll be happy.

Re: Fuel smell in cab
My friends 71 reeks of gas like crazy. If you just take a ride in it, you will smell like gas for the rest of the day. Good thing he doesn't smoke?

Re: Fuel smell in cab
I haven't seen a posting about another line in the cab. (Unless this is the evap line mentioned in # 19) I have a 72 which there was a gas line that had something to do with the accumulator under the hood. A gas line ran from the accumulator back to the fuel tank, however, before it ran back to the fuel tank, it went up a "B" post (can't remember if it's driver's or passenger's) did a U-turn near the roof and came back down. That was the problem in mine, it was rotten.

Re: Fuel smell in cab
I agree that something is probably wrong but mine smells like gas too. I did not find a leak on mine but I assume it is the filler neck or the sending unit gasket. I use my bed tank unless I go on a long trip.

Re: Fuel smell in cab
Replaced gas cap, both lines to the vent in the passenger B pillar, evap line on filler neck, and sending unit o-ring.
Total cost---- $18.53 Not worrying about exploding vapors in the cab------ PRICELESS! ![]() |
