Just bought a 89 camaro rs. The engine runs good, but i smell gas when i drive...the car seems like it is burning through gas at an abnormal rate...i dont race, or spin out, so what the hell could it be? any help would be great

 

Your car might be running rich, I know mine does, so I smell gas sometimes. But that's something you want to figure out quick.

 

I temporarily have my catalytic converter hollowed out till I can get a new one and the exhaust smells like gas, maybe yours is hollowed out.

 

There is a fitting with a tube coming out of it in the fuel rail under the plenum on the driver side. this fitting & tube feeds the cold start injector. the gasket below the fitting can leak, i would check it. Also the two rubber lines that feed the fuel rail, you'll see them on the driver's side just behind the a/c compressor, those can leak if not tight, or they can split and leak fuel. those are the causes of gas smell i my have found with my '88 sport coupe.

 

I thought my gas smell was from my evap system, I was going to block off my charcoal canister and go to a vented gas cap untill I could get everything to replace the canister and purge valve. When I went to pep-boys They let me take the cap out to see if it was the right tread(their system only shows the origional replacement), I took off the locked cap the PO had put on the car and found out it was a vented cap. Since the evap system was installed and I had changed all the vacuum hoses I bought a non vented cap. No more gas smell, and reclaimed about 3mpg. So check your canister, vacuum hoses and gas cap.

 

thanks guys, will look into it

 

Pull the vacuum hose on the fuel press. regulator, common for the diaphram to go bad.
Put a press. gauge on it to check for fuel pressure leak down.
