1990 350 tbi, strong gas smell in the cab

[VAL]

My 1990 Chevy 1500 with a 350 TBI, has developed a strong gas smell inside the cab. I've also noticed it takes just a bit longer to start also. Anybody have any suggestions on a fix? or where to start looking?

I would start with the pressure regulator where the lines enter the TBI.

Ya gotta be a leak somewhere. I never smell gas on mine, except after I changed the fuel filter I could smell gas outside the truck for a long time. That went away. So might be a leak around your tbi maybe the fuel lines loose???
