I'm running a freshly rebuilt 250 I6 and my tailpipe is cut off about 4 inches after my bed starts. My cab smells like gas, and that's understandable because my grandfather recently busted the fuel line going from the filler hole to my gas tank. The "problem" is that my truck, when running, smells like a dadgum gas tank. I've gotten used to it but my friends at school however, have not. I always get complaints of the smell from them when i leave my truck on in the school parking lot in the morning so i can use my heater. Is there anything i can do about this, is there something wrong, or do all older engine fumes have that faint gas smell?

Also check where the gas float wiring attaches at the top of the tank..Mine used to be wet there with a resultant gas smell. Regasket calk whatever to fix it.

If it's a line thats broke... they're available..fix the line/connections.

Solution: replace the fuel line or a piece of fuel line where it's broken. That, of course, assuming that's the cause of the smell.

No no I guess i didnt explain it right. Its not raw fuel smell. You can tell its burnt and its exiting from the exhaust pipe. Not a gas leak, im wondering if that smell from my tailpipe is controlable . Like why do modern cars not smell at all and mine does. Is it the cat?

I believe its probably normal old truck smell. Mine does it to, when the wind is just right, its prety bad in the cab if your not used to it. Add some tail pipe to move the fumes as far back as you can. Check all the fittings on the tank, fuel pump, and carb, just to make sure there are no more leaks. Rebuilding the carb might help some a long with a really good tune up. Joe

do you have any holes in the cab floor that would let in exhaust fumes check the rear corners for rust out

i started my 55 in the garage about 15 years ago with the door to the kitchen open..before we moved in..it took a week for "that" smell to go away. I've written posts about "that" smell also. It's a unique smell..gets in your clothes too..Not sure why it's so different smelling..possibly beause the unburned gases etc are not being reburned thru the carb.

Might check your float height, if the float is too high, the motor runs rich.

Yea im thinking it's runnin rich, thanks for the advice guys

It sounds like blow back from the crankcase, a common issue with the old trucks. New engines come with the erg valve that solves the problem at least I guess that's what does it.
