98 tj 4.0. I put a new skid on 3 months ago. Haven't had any issues until a few days ago. I put 3/4 of a tank of fuel and I smelled a strong odor of gas. I haven't filled it since I changed out tanks. Usually just put 1/2 tank in. Now that its down to a quarter tank I don't smell it nearly as bad. No sign of gas any where. Any thoughts? I've changed my tank out twice and both times it's been tough to get the filter threaded on. But both times it seems to have been on good when installed. What other issues could cause this?
