had fuel filter replaced and it leaked had problems for over a year. found out t on 2004 Chevrolet Tahoe

they replaced fuel line hose with non-pressurized hose. leaked fuel and smelled like fuel all the time they said they fixed it and it was not. replaced sensors and exhaust and catalytic converter. Would the leaking fuel filter and improper hose lead to this prob. had cosed P0156 and P0157 codes?

unlikly that it is related. Also the fuel filter is attached by union fittings. It should not have to disturb any hoses to install a filter unless they had to cut the line due to a frozen fitting.
