just follow the directions and you should be fine. My local diesel guy wanted $200 to fix it...i did it for 11$....6$ for orings and 5$ for shipping.

might as well change the fuel filter while you are there. with that you need to know if you have the OEM filter or the aftermarket. after market has the cap attached and OEM doesn't.

 

ok ill look in to in but its a pretty efty leak it makes a huge puddle on the ground but i will proble replace thos

 

Mine was also....was leaving a trail in the parking lot at work and a puddle about two feet in diameter. This is most likely your problem as it's a common issue. search around on here you'll see it discussed a lot.

 

ok thanks for the help man im planning on doing that this week
