fuel filter change question....

[gwilkrrs]

changed the fuel filters last night. trying to figure out what i am doing wrong since i cant avoid the diesel bath. i opened the drain on the rail filter, then removed and changed the top filter, the rail filter never stopped draining, it filled a 2 gallon bucket then went to a slow drip- i pulled the rail filter and got covered with a constent flow of fuel. truck had 3/4 tank. last time truck had 1/4 tank i did the top filter and didnt put lid back on and drained the rail filter- it never stopped draining completely and i took a bath. what am i missing or doing wrong?

You need to pull the top first or the fuel will siphon from the tank.

ok- thanks cause it definatelywas pulling from the tank.
are these the proper steps then?
1. remove top filter
2. drain rail filter
3. remove-replace rail filter
4. replace top filter

That's what I did. To drain the rail I just opened the fuel/water sep drain. After that stopped I did the rail filter. Only got a few drops when I opened it up. Oh, and I waited til the truck was almost on E to complete the job.

After the job is done: Prep the fuel lines by cycling the ignition about 6-8 times afterwards, without starting, for about 6 seconds each time. Started first try.

Just opening the top cap will prevent the siphon. So the first step is open the top cap.
