I own a 1999 K2500 3/4 ton Chevy Suburban with 156,300 miles with a V8 7.4 liter vortec engine it's throttle body injection. For some reason my fuel seem to disapear real quick. And sometimes I can smell fuel vapors when my truck is turned on but see no fuel leaks, no gasoline leaking on the ground. When I am driving gas burns about 4 miles now and and I can smell fuel vapors. Does coolant have anything to do with my fuel disapearing.

Thank you

No coolant doesnt have anything to do with fuel. You might have to get under the truck to actually see where it is leaking, sometimes the fuel will spread around and dry before dropping to the ground, especially if the truck is hot. Have this looked at IMMEDIATELY, fuel leaks are nothing to mess with. If no leaks are found, it may be a very rich condition with the engine, but have it checked for leaks first
