Loseing fuel on the sportage has 2.0L engine in it no leaks from tank or lines but can smell the fuel when first started in the morning and the heat turned on....were can i look now?....(no visible leaks on engine ither)
I had exactly the same problem. The problem was with the fuel line clamps directly under the air plenum on the right side of the engine, right above the fuel injectors. The solution is to replace the factory spring clamps with proper hose clamps - a buck each. The real problem is that to get at the inside clamp, you have to remove the air plenum. It took me about 90 minutes to get it off and the same to reassemble. Not all that difficult, just very time consuming.

Automotive dealerships, and most likely auto parts stores, sell a ultraviolet dye that can be added to your fuel system. The dye is visible to the naked eye, but much more pronounced when ultraviolet light hits it. If you wanted to attempt finding the leak yourself, add the dye directly to your fuel tank, and purchase a ultraviolet flashlight at an auto parts store. Some auto parts stores may possibly carry this light in their "loaner tools" so you may be able to rent one at essentially no cost to you. Follow your fuel lines and evap system with the light until you find the source of your leak. Or if you are more comfortable having a repair shop find the leak, mention the dye to them. Its entirely possible they may not know such a dye exists.
Any leaks from where the fuel line comes in? Could be a leaking exhaust header causind the smell. Check your hoses and lines and make sure none of them are broken or rotted. is the engine loud when it's at idle and parked?
check the fuel line hose near the fuel regulator for wear as they tend to leak or corrode causing a gas smell inside the car. My 2000 Kia Sportage just had the same problem with the gas smell inside the car.
the first thing to do is look under the car at the plastic canister the vaper recovery system it is in the rear some times it is coverd by a sheild the vacuume hoses are bad if you smell gas and that will turn the light on it works off a pressure senser on the tank check all the hoses
