another fuel filter question

[01-TD]

Hey guys I'm new to diesel and the site, you guys are awsome!

Here's my question. Is there a special tool or trick to take off the cap?
I tried by hand it's to tight. Also the yellow lever behind the cap what is it for?

My truck is a 01 350 7.3L auto

I use my oil filter wrench to losten the cap on the fiel filter. I'm sure it isn't the right way but my BIG channel locks really tear it up. The little yellow knob is to drain the fuel bowl. ( all over your garage so EVERYTHING smells like diesel fuel-- a pan helps )

It depends on which cap you have. There is one that will except a 3/8 or 1/2 ratchet, I don't remember the size. Then the one that comes factory, I just use a wide cold chisel if its tight, and a soft hammer. That should knock it loose. Just remember to replace the O-rings in there and lube them with clean diesel fuel or assembly lube and they'll come off easier the next time.

Wow you guys are quick!

I'll try using a blunt object to break it loose.
Also could you explain the purpose of the fuel bowl and why and how often it should be drained?

Its basically called a fuel/water separator. Its used for just that, separating water from the diesel fuel. Diesel fuel has a tendencie to collect condensation. Everytime you change your fuel filter you should drain the bowl. Mine gets changed every 9-15k miles.

OK

Do you hold it till no fluid comes out?

you dont have to hold it. it is a lever that can be left open or closed.....so make sure to close it all the way before turning the key on........but yes, if you intend on draining the bowl, put a drain pan under the tube that comes down on the left front of the motor.....open the valve and let the fuel drian till it just dripps out....close the valve, replace the filter, and turn the key on. let the key stay on for 20 seconds or so, turn it off, and turn it back on. then start it when the wait to start light goes out.........Marc
