Bad MPG! Fuel leak found, I think, help?

Hey all. I have been getting about 15mpg on my last few tanks. Usually I get 17-18mpg. I havent changed my driving style, so I assumed it was the cold weather here. Its been below 30 alot.

So, I get out the truck today after another disapointing fill up and smell fuel. Pop the hood and climb up and behind the fuel filter housing it was wet. Theres a bit of fuel in the valley, and the plastic valve (yellow hadle) that bolts to the housing are all wet and smell of fuel.

Anyone had the bowl drain valve leak? Im assuming the valve is changeable seeing as 4 bolts hold it onto the housing. What do these valves cost?

Mine was leaking about a week ago. I found some o rings online but didnt have time to order them before I left for school. I took it off and tried to find some at the parts store but didnt find any, ended up just putting it back on and it hasnt leaked since. Just got lucky this time but Im sure its just the o rings leaking.

Confirmed, overnited some from DFUSER.com replaced them and voila no leak.

Glad to hear you fixed it. I just filled up and since I stopped my leak and got my boost pressure up a little bit my mileage was better this tank.
