Be careful! Check the fuel lines around the filter and near the tank. If they're old and cracked they may be seeping and it can get worse in a hurry.

near the fuel filter correct

I'd get those replaced ASAP.

could this account for cel codes as well

Sure, the fuel pressure and delivery could be off.

sounds right i went to auto zone to get a print of the cel codes
p1188-po170 and another but the explantion said either large vacuum leak - fuel pressure regulator- or injector

I just noticed the smell of gas last night from the engine bay. Looks like the T connection for the injector in the intake manifold is leaking a bit, i put fuel injector cleaner in there a few days ago so i think it may be causing some leaks. Might just get some braided line and redo all my fuel lines.

Yeah, you wanna make sure there are no fuel leaks for obvious reasons.
